Audiophiles rejoice: Samsung Galaxy S III contains a Wolfson DAC

Despite my initial disappointment with the external hardware of Samsung's new Galaxy S III, you can't deny that the device contains all the right sort of specs that would make it a successful flagship smartphone for 2012. Today, whilst lurking on my favourite audiophile headphone forum, Head-Fi, I stumbled upon a thread that confirms that the Galaxy S3 will contain a Wolfson DAC. That is a pretty awesome news if true, and will make the SGS3 a serious challenge to the Xperia S, at least when it comes to audio output.

Announced earlier this year, the Wolfson Micro WM1811 codec is allegedly similar to the one found on the highly regarded Samsung Galaxy S and Nexus S. This is awesome news because those two devices were actually rather good sounding. According to Wolfson's white paper, the WM1811 is a low power codec featuring a 24-bit 2-channel hi-fi DAC with 2 x 2W stereo speaker driver. It is capable of delivering 100db signal-to-noise ratio on DAC playback.

When Samsung removed the Wolfson DAC from the Galaxy S's successor, the Galaxy S II, there was a minor uproar within the headphone community. Wolfson after all powers most of Apple's none-touch iPod DAPs. With up to 64GB of storage plus another 64GB via an external microSDXC card, the SGS3 is set to be a favourite with audiophiles. FLAC anyone?

Nokia BH-905i first impressions

Today I received a Nokia BH-905i headphone review unit. Thanks to WOMWorld/Nokia for the loan. This is part of my #NokiaLondonLoop kit, which I will be tweeting about next week from the famous Sarm Studios in Notting Hill.

Back to the BH-905i (who names these things?) first. The headphone is a wireless Bluetooth supra-aural headphone that doubles as a headset, and also features Active Noise Cancellation for noise isolation. Now any sensible headphone enthusiasts will know that ANC pretty much introduce sound artefacts, and it is no different here. Over the next couple of days I will pit the BH-905i against Britain's ageing and noisy railway trains and see how well ANC really works, and whether it is worth enabling it at the expense of sound quality.

The built quality of the BH-905i is excellent. The supra-aural pads are comfortable, though they, unsurprisingly, provide very little passive isolation compared to closed back headphones with circumaural design. The headband is also padded. Inside each BH-905i contains a none user-removable 600mAh battery. Nokia quotes a battery life of 24 hours for music playback via Bluetooth without ANC, and 16 hours with ANC enabled. Fortunately you can use it as a wired headphone.

The right earpad houses the majority of the controls, including a volume rocker, play/pause button, previous and next track and a multifunctional key that controls the call answer/end, voice calling/redial and power on/off features. The left earpad contains a solitary switch to turn on ANC. Aesthetically, they don't look that great but who cares - all that matters is the sound quality.

Sound wise, it is warm sounding, with limited sound staging. Mids are forward. Lows are tight and clean, but lack any sort of impact. Clarity is excellent. With an impedance of 32 ohms, the BH-905i is easily powered by most modern DAP and mobile phones.

Look out for a full proper review in the next week or two.

Sennheiser RIP

Prof. Dr. Fritz Sennheiser, the founder of Sennheiser, has passed away.

Put simply, without him, I would never have had the pleasure to own and listen to a IE 8, the greatest IEM Sennheiser has ever made - or indeed the countless of other Sennheiser headphones I've worn so many times in over ten years since I discovered the joy of headphones and portable music.

Thanks Sennheiser!

x-JAYS announced - quad armature IEM

Swedish headphone designer/manufacturer Jays has today announced a range of new IEM models to be released this year, of which the most interesting to me is the high end quad armature x-JAYS (due out second quarter of 2010). Not a lot has been said about it yet, but based on the press release I am going to guess that the x-JAYS will feature a four-way crossover, where each armature speaker operates on each own frequency. Still what do I know? In any case I'll try to procure one for review... so watch this space!

Due out sooner are the a-JAYS and t-JAYS (pictured). Even less are known about these, though it is probably safe to assume that the t-JAYS at least would feature a micro balanced armature-based architecture, if the preview image of it is anything to go by.

Excited? I know I am.

Audio Technica ATH-ES7 impressions

Got the Audio Technica ATH-ES7 a couple of days ago. Be aware that I only have had a couple of hours of listening time with it, so this is merely a first first impressions. You do not get much with the ATH-ES7 - just a cleaning cloth and handbag pouch to store the headphones in. As this is a headphone designed for portable use - no 3.5mm to 1/4" adaptor is provided, but you can easily get that for a quid or two from any hi-fi store.

The build quality of the closed back ES7 is brilliant (though I would prefer a studier cable). The cups are made of stainless steel and offers a mirror finish that attracts fingerprints (this is where the cleaning cloth comes in handy). The overall design is a step ahead of Sennheiser within the same price range. It is pretty clear that with the ES7 (and most Audio Technica products), you are paying for the design. Fortunately they also sound good, unlike the typical junks you find in high street stores like HMV.

The ES7 is pretty easy to drive and I did not encounter any issues pairing it with my Walkman and Nokia E55. As for the sound - it is flat and 'neutral' with good extension. The bass quantity is decent, though the impact is of no match for my Sennheiser IE 8 (it does scale well with an equaliser). Treble wise, it is somewhat rough and 'grainy'. My partner who plays piano with this, confirms this as well. We will see if things improve after the initial 'burn-in' period.

Look out for a full review in the next two weeks.

Westone UM3X IEM review

The UM3X is Westone's flagship universal fit IEM designed for musicians and replaces the much liked UM2, as well as a cheaper alternative to the custom high-end ES3X. It isn't aimed to replace the much hyped Westone 3, which was designed for consumers and audiophiles. This is the first universal fit ear canal headphones that contains contains three balanced armatures with a passive three-way crossover - the same technology used on their flagship custom ES3X (which incidentally costs more than double the price of a UM3X).

Specifications and stuff:

Frequency response: 20 Hz – 18 kHz
Sensitivity: 124 dB SPL/mW
Nominal impedance: 56 ohms
Transducer: Three balanced armature transducers with passive three-way crossover

I have been listening to it for the past week, on and off in between sessions with my Sennheiser IE 8 and Denon AH-C710. These three comes at a completely different price point with the C710 costing the least, IE 8 around £180 and UM3X about £300 in the UK. I'll share my thoughts about the C710 in another review, but right now let's get to business regarding the UM3X. The UM3X sounds good, but the sound signature is an acquired taste. The sound quality here isn't disputed - it is great if you can afford the entry price - but as usual, try to borrow one or seek a test unit to hear it before buying.

As before, my tip of choice are the Klipsch gels that can be found on their Custom and Image series. They fit the UM3X perfectly, has the same bore diameter and are very very comfortable (at least for me). Beware that the sound signature will be dependent on your choice of tips. They come with Comply tips, which isn't something I would normally prefer to use. Another tip that can fit the UM3X is the Shure foamies (black olives).

Both Comply and Shure black olives offer superior sound isolation, and in theory should offer improved bass response. I do not like using them because I find them 'muffled' and hate the icky ear wax that tends to hang on to the surface. They also cost more in the long term, though people with no issues spending £300 on a ear-canal monitor will have no issues with spending £13 every couple of months on new Comply tips.

The built quality is excellent. I can't judge its long term durability, but they do seem tough enough. I have my doubts on the cables though. The braided cable has its uses - it remains supple and kinky-free throughout - though I did manage to get it tangled once. Even better the cable is microphonic-free (the echos you hear when walking and cable rubbing is due to microphonic cables - an example would be the popular CX 300 and EX71.

Unfortunately despite the cost, the cables are not modular - meaning you will have to send it back to Westone should the cable gets damaged. Also the length between the earpiece and the Y-splitter seems a little too short (in comparison the C710 is too long, and the IE 8 about perfect). I didn't find a braided cable brushing my neck to be extremely comfortable.

The UM3X is smaller than I thought. Considering that they have managed to cram in three balanced armature transducers inside each ear piece, the UM3X is an example of the technical achievement of the engineers at Westone. They fits well in my ears and I never had a problem with seal. Isolation is better than the IE 8 (with standard single-flange silicon tips), though this could be both positive and negative. The lack of isolation with the IE 8 is one of the reason of its airiness and vast soundstaging.

They seem to be as comfortable as the Klipsch Customs (easily the most comfortable IEMs I have ever had the pleasure of sticking inside my ear canals). Also, the UM3X sits flushed inside my ears, so I guess most will not have any issues sleeping with them. I wouldn't recommend sleeping with it though, considering the cost and the lack of replaceable cable.

Because of the higher than usual impedance (most consumer IEMs has 16 or 32 ohms), the UM3X suppressed most hiss that comes from lower-cost DAPs. I find that the UM3x is a bit more forward than the IE 8, particularly in the mids and vocals. They sound great with vocal-based performances and genre, though at the expense of bass and treble. It also sounds warmer than I initially expected it would be and I experienced no fatigue despite long sessions with it (two hours or longer). There are no issues with sound quality and music output was clean and clear throughout.

They are definitely bass-light and has very little impact, not surprising considering the use of balanced armature transducers, but should be sufficient for most people. If bass quantity is something you seek, get something with a moving-coil dynamic driver like the IE 8 or Denon C710. Regardless the bass is deep and controlled and does not interfere with the music. Treble quality is brilliant, and I detected no sibilance. They have some sparkle, but lack the dynamic of the IE 8. Soundstaging is pretty decent, but is tighter than the IE 8. In any words, the UM3X offers a more head-staging experience, particularly the vocals. I feel at times if the singer was right next to me, where as with the IE 8 I tend to feel like an audience a couple of seats from the front stage.

Westone's flagship universal is definitely one of the more boring IEMs I have heard, with its flat presentation. I love the dynamism and in-your-face all-around performance of the IE 8, which seems to be designed for people keen on listening to music. The UM3X is a high-end stage monitor designed for musicians, where as the IE 8 and other alternatives (like Westone's own W3) are geared towards us consumers and listeners.

Do not get me wrong, these are brilliant IEMs, but as I said earlier, they also cost significantly more than the IE 8 (in the UK - in the US and some other countries the pricing gap is smaller). The issue of sound preference is definitely a subjective one. I know of people who would love the UM3X where as some will dislike it outright.

If you are a budding musician who is keen on getting a quality in-ear stage monitor without the budget for moulded custom IEMs, then perhaps the UM3X will be great for you. I don't know since I don't know squat about making music. For consumers who tend to listen through a portable digital audio player, try out the Westone 3, Sennheiser IE 8 and Shure SE530 first. Those may be better suited for you.

Westone UM3X first impressions

This is it, the Westone UM3X. In my hands (or should I say... my ears!). Thanks to @mark2410 for loaning me his. I've only managed to listen to it a couple of hours, but I am deeply impressed by it. I will eventually compare it with my IE 8 (of which has close to a thousand hours on it). Both offers completely different sound signature. It is just a matter of pinpointing your preference. The UM3X is likely to appeal more towards owners of other balanced armature IEMs like the Shure SE530, but I only have the IE 8 here to compare with.

My tip of choice are the Klipsch gels that can be found on their Custom and Image series. They fit the UM3X perfectly, has the same bore diameter and are very very comfortable (at least for me). Beware that the sound signature will be dependent on your choice of tips. Impressions and the following review (next week?) will be my own, so please do not flame me for stating my opinions. I also would not comment about multi-flange ear tips, as I do not find them as comfortable. This is due to my shallow ear canals (one reason why the IE 8 with default single flange silicon tips are perfect for me).

The UM3X fits well in my ears and I never had a problem with seal. Isolation is better than the IE 8 (with standard single-flange silicon tips), though this could be both positive and negative. The lack of isolation with the IE 8 is one of the reason of its airiness and vast soundstaging. They seem to be as comfortable as the Klipsch Customs (easily the most comfortable IEMs I have ever had the pleasure of sticking inside my ear canals). Also, the UM3X sits flush inside the ears, so you will not have any issues sleeping with them. I wouldn't recommend sleeping with it though.

As I only have had a couple of hours with them, I won't comment much about the sound quality. But they do sound good, and even more importantly, do they sound £120 (price difference in the UK) better than the IE 8? I can't say for sure yet. They are a bit more forward than the IE 8, particularly in the mids. The bass is just a bit behind the IE 8, and has some impact, though not quite there. Just a note here that I am no bass head and I never found the bass on the IE 8 (mininum dial) to be overwhelming. Because the UM3X are fitted with balanced armatures, bass impact will definitely depends on seal and tip type.

Westone's flagship is definitely the more neutral (and thus 'boring') phone of the two, but right now I am leaning more towards the IE 8 in terms of sound preference because I just find it to be more musical. Having said that I can't yet reach a conclusion (especially with so few hours with it). All I can is for sure is that the UM3X are very good IEMs (there are no such thing as poor performing high-end IEMs - they all depends on your preference), but they also cost significantly more than the IE 8 (in the UK - in the US and some other countries the pricing gap is smaller).

Look out for my review sometime in the next week or two once I have a bit more time with it, and then another one for Denon's flagship AH-C710.

CrossRoads MylarOne Quattro in-ear headphone review

You may have never heard of CrossRoads, but their MylarOne line-up of ear canal headphones has been well received at headphone forums as capable of offering good audio quality at a reasonable price level. As far as I know, their products are not sold in Europe, at least not in traditional outlets. However you can get them from Jaben.net (thanks to Uncle Wilson who has kindly supplied this review unit).

With the new MylarOne Quattro, Crossroads is aiming to bring a pair of reasonably priced customisable headphone to the masses. The Quattro features interchangeable “tuning plate” screw-on bass ports, that allows the listener to customise the desired sound to their liking. At US$88 inc. shipping, the Quattro is one of the cheapest in-ear headphones that allows the listener to option to do so, and significantly undercuts its competitors by a wide margin (price wise).

Specifications and stuff:

Frequency response: 20 Hz – 22 kHz
Sensitivity: 95 dB at 1 kHz
Nominal impedance: 16 ohms
Transducer: 7mm moving coil dynamic
Cable length: 1.25 meters

The Quattro arrives in a small and simple card box packaging that isn't a pain to open. Bundled inside includes four pairs of single flange silicon ear sleeves, a pair of dual flange silicon ear sleeves, an airplane stereo adapter, a shirt clip and a small pouch. You also get three pairs of the screw on bass ports labelled with '1', '2' and '3'.

The build quality of the Quattro is actually pretty good. The Quattro itself seems to be made of anodized aluminium and is very tiny. It is actually the tiniest IEM I ever held. The housing features a clinder design and holds a small 7mm moving coil dynamic transducer. The silicon sleeves are soft and supple, and reminds me a lot of the Klipsch ear gels (easily the most comfortable ear sleeves I have worn). Like the Radiopaq, there is no mesh or filters on the nozzles to prevent dirt and ear wax from entering. I am guessing that it features a similar design to the Radiopaq which features a built-in protection at the driver level. Overall, I have no complains about the build quality of the Quattro earpiece itself.

Unfortunately the cable appears to suffer from slight microphonics. CrossRoads cleverly supplied a shirt clip (already clipped to the cable), which can help with reducing the amount of microphonics. Wearing the Quattro over the ear will also help a lot. A Y-slider is included which you can also use to help reduce the microphonics. On the upside the cable is soft and do not kink as easily as the Radiopaqs or tangle much. It terminates at a 3.5mm headphone jack that is angled slightly (comparable to the Klipsch Image X10).

Because of the size and lightweight-ness, the Quattro is very comfortable on my ears. They feature a deep insertion design that allows for greater isolation in comparison to other headphones like the Sennheiser IE 8. Unfortunately my ear canals are quite shallow so the Quattro sticks out quite a bit more than say, IEMs that features a flushed design. This makes sleeping with it almost impossible. Still people with deep ear canals may find the Quattro to be ideal for sleeping, but mileage my vary.

Now, on to the important bit: the sound quality! Based on other owners experience I subjected the Quattro to 100 hours of intense burn-in. The three pairs of bass ports does affect the frequency response by quite a bit. Port 1 offers the heaviest bass response, with port 2 in between and port 3 offering the lightest.

Unfortunately before doing my final testing, one of my part 3 port suffered a mishap when the adhesive that held a cover that closes the port's vent loosened and fell out, trapped inside the Quattro itself. I was able to remove it, damaging the cover in the process. This does mean I am unable to accurately judge the performance of port 3 at this stage of burn-in. However based on previous tests (before the cover fell out), I found that that port 3 offered a very bass light sound, with greater treble detail at the expense of soundstaging.

Personally I found that the bass response with port 1 to be too much. The treble quality doesn't seem to be affected much, but they are slightly more recessed than port 2. Soundstaging wise, they are the widest and has an airy sound. Instrumental separation could be better, but they don't sound congested. They have a nice warm sound, but so does port 2 and 3. Port 1 also happens to isolate the less due to the vent, though not by much.

Port 2 is my favourite port to use with the Quattro. They offer a bit less bass than port 1, whilst not changing the overall warm sound signature much. The soundstage narrows a bit, but is still wide to enjoy classical music. The clarity is actually pretty amazing with port 2, with good amount of transparency. Mids are detailed and lush, with good but slightly recessed vocals. The treble isn't too bad either and I detected no apparent sibilance. Bass impact is punchy, but without the overwhelming quantity of the first port, and certainly no where near the speed, tightness and impact of the IE 8.

The Quattro is any interesting product. The price range puts it up against plenty of established brands and products, including Klipsch (with their new Image S4), Sennheiser CX 95, Denon AH-C551 and the Radiopaqs. The warm and fun sound will almost certainly please many people, but the sound quality isn't nearly as good as the CX 95, Radiopaq Jazz or the discounted Klipsch Custom 2. However if you want a customisable in-ear headphone without the large price tag, the Quattro comes highly recommended.

The CrossRoad MylarOne Quattro is available for US$88 with free worldwide shipping from Jaben.net

JVC and rip-off Britain

JVC's HA-FX1000 has been gaining some attention lately as being a Sennheiser IE 8 killer, what with its use of wooden diaphragms and stuff. But suspicion has emerged that it is merely a renamed version of the old cheaper FX500 model. Unfortunately there hasn't been any proof and all evidence so far were circumstantial, until now.

Today a fellow Head-Fi'er Soozieq decided to call JVC UK and spoke with someone called Richard who confirmed that the FX1000 is indeed a rebranded FX500 and has been renamed specifically for the UK release. Now here's where it gets all nasty. The FX500 only costs £70 at Amazon.co.jp whereas it is sold here (under the FX1000 moniker) for... wait for it... £250! That is 3.5 times the price in Japan! Nothing wrong with that as at the end of the day it is the prerogative of the company to price their product whatever they want, but the deliberate attempt to mask the version by doubling the product numbering to make it appear as a new version or an upgrade really takes the piss. Odd my arse.

I have mixed feelings about this. On the one hand, it is mighty tempting to import the FX500 from Japan as they appear to be good value for money. But on the other I am pretty darn pissed off with JVC and/or Apple for deliberately attempting to mislead and price gouge its potential customers. I know us in the UK are no strangers to being ripped off, but this is a whole new level. If JVC thinks that they can get away with this then they can duly fuck off. My money will instead go towards other (less evil) companies.

Radiopaq Custom Tuned Earphones review

Radiopaq has made big claims over their new range of headphones, which they dub as Custom Tuned Earphones. Costing £59.99 each, the four IEMs are customised to different types of music: Classical, Jazz, Pop and Rock, but will also sound great regardless of whatever genre you throw at each individual headphone. So is the Custom Tuned Earphones a shrewd concept cooked up by marketing of a way getting customers to hand over their money four times, or is Radiopaq really onto something?

Specifications and stuff:

Frequency response: 18 Hz – 20 kHz
Sensitivity: 120 dB
Nominal impedance: 16 ohms
Transducer: 10mm moving coil dynamic
Attenuation: up to 26 dB
Cable length: 1.2 meters
Warranty: 2 years

One thing Radiopaq is right on the money is that different people has different sound preference. What they did is tune the four individual models, through customising the transducer drivers, chamber shapes and bass ports in order to produce the frequency response that their engineers believe would distinguish each versions from each other. This allows for differentiation that offers people with a degree of sound choices, all without the confusing audiophile terminologies.

Unfortunately it also presents the would-be customer with some tough choices. For many £60 is a lot of money to spend on headphones, so getting it right would be important. And what if, like me, a person listens to a wide range of musical genres? No problem says Radiopaq, you will still be able to enjoy other genres with them, even going on to likening their headphones to different sort of cars.

Sadly, until you are able to listen to all four models, there is no way to know which models really suit you. With the Rock version, you get big warm and powerful sound, with plenty of bass and good mid-range. The Pop IEMs offers forward vocals with good clarity and a bit less bass than the Rock version. On the other hand the Jazz model gives you a more balanced sound, with adequate amount of bass impact and sweet vocals. Finally if you prefer Bach to Burt, the Classical version delivers more on the mids and highs with a greater soundstaging, but by sacrificing any sort of bass impact.

It all boils down to personal preference. I personally found the Rock version to be too bassy and the Classical version too flat and dull, but some may just prefer the sound. My classical piano-trained partner offered her opinion on the Classical version as sounding flat and neutral, capable of capturing every nuance of a good classical recording. The Jazz version is sweet sounding, which I find perfect for listening to tons of indie pop and twee, where as I use the Pop version for good amount of trance and electronica, as they provide just about the right amount of bass and very fun. Instrumental separation could have been better with all versions, but they are not too bad.

They also lack the vast soundstaging (burn-in will improve this), clarity and fuller in your face sound of my Sennheiser IE 8, but then again the IE 8 costs three times as much as an individual Radiopaq. If I have to pick one of the four, I would go for the Jazz as it allows me to relax in between sessions with my IE 8. It is less bold, softer, slightly colder and ideal for chill-out sessions (like before sleep). Unfortunately the design meant that it sticks out of my ear a bit and thus is physically uncomfortable to sleep-in. The Pop version is better in this regard as they are as tiny as the CX 95, and has an overall better fit.

It is actually nice to find that the enclosure is indeed made of metal. Even the nozzles are metal. They feel very tough and yet light. The same however can't be said about the cable. The cord seems tough, but they kink a lot, and are also microphonics. The microphonics isn't as bad as the Sennheiser CX 300, but they are still noticeable. They can be worn over the ear, which can somewhat alleviate the microphonics issue. As for fit, the Pop version first my ear the best due to its small size. Coming up on the rear is the Jazz version due to its rather large housing. The silicon taps are also proned to pick up dirt easily, though John of Radiopaq did inform me that they are looking into alternatives including foam tips. Isolation is on par with my Sennheiser CX 95 and s-Jays, but no where near the Klipsch Customs.

At £59.99, the Radiopaqs do offer plenty of value, but getting them all would mean spending just under £240. For that you can get a Sleek Audio SA6 (US$199), or the Sennheiser IE 8, which while only allows you to customise the bass, has overall better clarity. Another would be the CrossRoads MylarOne Quattro, which at US$88 may be a serious contender to the Radiopaq, whilst also offering interchangeable bass ports.

All in all, the Radiopaqs surpassed my expectations. They don't come with plenty of frills - in fact just the headphone and three pairs of single-flanged silicon tips are included within the retail plastic case. But what you do get is a pair of headphone with good sound quality/price ratio and a two year warranty to match. I find them better than the equally priced Denon AH-C551, and just about equal to the Sennheiser CX 95. The Jazz version in particular is a keeper and I have no qualms about saying that this version is one of the better sub-£100 in-ear headphone I have heard.

The Radiopaq Classical, Jazz, Pop and Rock are all available on Amazon UK. Radiopaq has plans to launch the IEMs in the US in the future, but you can always get them from their own online store now.

+ Great sound quality/price ratio
+ Good build quality
+ Two years warranty as standard
+ Very light
- Kinky and microphonic cord
- Packaging

Audio Technica ATH-SJ5 headphone review

Audio Technica's ATH-SJ5 is a budget supraural DJ-style portable headphones. The design is very typical Audio Technica and, though not as eye catching as the ATH-ES7, is still a very stylish headphone to look at. I wouldn't think that anyone would be embarrassed to be seen wearing it.

Like other portable headphones such as the Sennheiser PX 200, Grado SR60 and the more expensive ES7, the SJ5 is foldable. This makes transporting the headphone a far more convenient process than most full size headphones. It is a shame that no carry case is included. Also with an impedance rating of 32ohms, the SJ5 is an ideal headphone for music lovers not wishing to carry an additional external amp and has no love for intra-aural canalphones.


The build quality is good enough (at its price range). While primarily made of plastic with dashes of metal, the SJ5 is solidly well built and does seem to be capable of standing up to the abuse of everyday listening. The headband is simple and isn't too thick to give the wearer any hair issues. The folding hinges is also solidly build, and I have not encountered any problems with the folding mechanism yet. The cord is the ideal lenght for portability, but is also rather thin.

I found the SJ5 to be very comfortable to wear for long periods of time. The supraural earcups are made of faux leather, I believe, and sits well on my ears. They also do not exert much clamping pressure on the ears. The headband is also easily adjustable. Each of the headphone housing is flexible and can be swivelled, ideal for monitoring.


Having gotten used to IEMs in recent years, it took me some time to appreciate the sound of a mid-sized headphone. There is an adequate amount of bass. The bass response isn't bloated, in fact it is clear and tight, if a bit slow. More importantly it does not overwhelm the mids, which are very warm sounding and detailed. The highs on the other hand suffers from some roll-off, though not as much as I expected. Overall I have to say that the SJ5's output is detailed with all around good clarity. They do not leak as much sound as I thought, which is a blessing on the Tube, but they also do not isolate well (duh). However I personally would have preferred a slightly warmer sound signature.

Like every other Audio Technica headphones, they are quite a bit more expensive overseas (around £45 in the UK) and you do not get much (basically just the headphone and nothing else). The SJ5 is lightweight and offers an acceptable sound quality, whilst also being slightly cheaper than other similarly spec'ed headphones. I consider these a bargain if you can find them for in Japan (as low as US$35), but I suggest checking out their competitors first before plucking down nearly double in import tax.

JAYS s-JAYS in-ear headphone review

You may never have heard of JAYS. They are a Swedish headphone manufacturer who have lofty ambitions to conquer the headphone market through churning out models with good technology and design for the fashion conscious. Check out the q-JAYS, which is one of the tiniest and most desirable looking dual balanced armature in-ear monitors in the world. But with most consumers not willing to spend more than £100 on headphones (or indeed at all) recession or not, the s-JAYS at half the price is a much more tempting proposition.

At £60 retail (£43 on Amazon UK), JAYS have the mid-range market well covered with the new s-JAYS. These, according to JAYS, is their first in-ear headphone to use the SIREN armature technology - whatever that means. Featuring a new tubeless round design, they are said to be capable of delivering plentiful of bass and open soundstage, something balanced armature technology isn't exactly known for. A normal armature transducer is typically shaped as a longish rectangular box, where as the SIREN armature here is shaped more like a dynamic transducer. This explains the apparent large body size of the headphones.



Specs:

Frequency response: 20 Hz – 20 kHz
Sensitivity: 113 dB SPL/mW (1mW)
Nominal impedance: 69 ohms) @ 1 kHz
Transducer: SIREN armature
Headphone weight: 10 grams

Included in the sales package are plentiful of accessories, something JAYS should be commended here. Six pairs of ear tips of varying sizes are included (five pairs of silicon sleeves, one pair of foam sleeves). You also get a small zipped faux leather carrying case, extension cable, four pairs of earwax filter, stereo splitter and an airplane headphone adapter. The filters are required to prevent dirts, ear waxes and spiders from entering the s-JAYS nozzles. To be honest I do believe that they should bundle an ear wax cleaning tool instead or provide a permanent protective mesh as these filters are expensive to replace! Having said that I do not suffer from excess earwax issues and reckon a single pair to be able to last me more than a couple of months.



For an in-ear headphone with a single armature in each earpiece, the s-JAYS are pretty huge, no doubt due to the dynamic driver-like design of the SIREN armature drivers. The caterpillar or bee-like design is an acquired taste, but I generally like them even if they are a bit too large. They look nicer in person than in promo pictures. Despite the size I didn't had any issues getting a fit. They slot into my shallow ear canals rather nicely. The fit is overall better than Denon's C551. They do not sit in as deeply as the Klipsch Custom 2 or my Sennheiser CX 95 though.

Both the symmetrical main cord and extension cord terminates at a straight gold plated 3.5mm plug. Having experienced Sennheiser's extraordinary new cord, I find the cord here to be nothing special. JAYS doesn't think so and they do make pains to highlight the quality of the cord (including a sticker on it). They do seem tough and capable of withstanding abuse, plus they do not get tangled easily. However they are rather stiff. On the upside microphonics is minimal. The Y-splitter also look rather fragile in comparison, but it is no better than the one on the Denon C551. Like the Denon and Klipsch headphones, there is a Y-adjuster which is useful for tightening and preventing microphonics.



The s-JAYS driver housings are made entirely of plastic and are very light to hold. The lightness does make it feel cheaper in comparison to the aluminium housed Denon C551 and CX 95. Still they are comfortable to wear for hours at a time. The biggest design flaw of the headphones is the decision to print the 'L' and 'R' labels in the same colour as the body! The letters may be raised, but they are still troublesome to locate. When will manufacturers learn we want colour coded headphones?!? I found that the default single flange silicon tips to fit perfectly in my ears. They do not leak sound - not surprising considering the lack of air vents. The isolation is also on par with my CX 95. The silicon tips themselves are soft and a bit thicker than the default one provided by Sennheiser, Sony et. al.

Enough chattering. Question remains, how good does this SIREN armature powered s-JAYS sound? Well I had a chance to listen to it during the whole long weekend away at the Lake District and here are my thoughts. JAYS has made it clear that the SIREN armature transducer here produces more bass than equivalent single balanced armature drivers. They do sound plenty, at least more than the last single balanced armature IEM I had which was the Klipsch Custom 1. They do not extend as low as the Sennheiser IE 8, but the mid-bass hump is definitely there. The bass impact is certainly one of the better ones I have heard outside that of the IE 8 or CX 95.



Unfortunately the mids do get overwhelmed by the bass. It isn't like the IE 8 where even with strongest bass setting, the mids remained forward, clear and precise. Here the mids are recessed, shoved to the back so to speak. The highs on the other hand are only slightly recessed and fortunately they do not suffer from sibilance, or at least my ears did not detect any. Sadly I have to agree with many others that complex music do not work well with the s-JAYS. The sound quality easily gets muddy and veiled. My month old relationship with the IE 8 does not help either, but please please remember that the IE 8 is triple or quadruple of the cost of the s-JAYS. Compared to the CX 95, the s-JAYS are a bit more detailed, but lack the warmth and fun of the similarly priced Sennheiser.

The soundstage is sufficient. They still provide a more headstage kind of sound, in that the music revolves inside your head, rather than around. However as far as imaging goes, the s-JAYS performs well here in comparison to other armature based in-ear headphones. If you require something with a larger soundstage, then get an IE 7, IE 8 or full size cans. Ultimately the general rule is armature technology has so far been unable to provide a more encompassing soundstage compared to dynamic technology, so keep that in mind the next time you go headphone shopping.



All in all I quite enjoyed the s-JAYS. It won't replaced my IE 8, but it makes for a reasonable backup headphone. For those who can't see the point of spending more than £100 on headphones, these are also good enough to be used as your everyday pair. At £60, I do think the s-JAYS are a bit overpriced, but they can be had for £43 from Amazon UK or even cheaper elsewhere (I've heard that Costco had them for £35 once - you may want to check there). At that price I would recommend them - but do check out their competitors as well.

+ crisp sound
+ good amount of bass for armature
+ bundled accessories aplenty
+ good sound quality for price
- nice looking packaging hampered by the requirement to package products in blister plastic packs
- recessed mids
- filters, I hate them

JAYS s-JAYS unboxed

Firstly, thanks to Peter at JAYS for giving me the opportunity to try out the new s-JAYS in-ear headphone.

As I have had it for less than a day, I won't be commenting about the sound quality just yet. I'll be going heading off to Cumbria later today and this will be the headphone of my choice for the long weekend trip. The trip will give me an excellent time to test out the isolation, comfort and sound quality of the s-JAYS in between sessions of trekking, lunching and whatever it is people in the country do. You can also follow my ramblings on Twitter, the platform of which I shall delegate my mobile blogging on.

Anyway here are some pictures.

The box is rather eye catching:



You will need a pair of scissors to cut through the plastic defenders here:



Plenty of frills are included here: stereo splitter, airplane stereo adapter, extension cord, replaceable ear wax filter, small case, assortment of silicon and foam tips:



Noticed how large the s-JAYS are in comparison to the IE 8 and CX 95. There is a reason for that...:



Trance and electronica music in general do seem to pair well with the s-JAYS:

Denon AH-C551 in-ear monitor headphone review

Denon is one of the most prestigious hi-fi brand. Their range of full-size headphones has often received plenty of accolades from audiophiles. The Denon AH-C551 is one of their first forays into the world of in-ear monitor portable headphones. At around £50 per pair, the C551 is designed to compete with the headphones like the Sennheiser's CX 95 (now discontinued and replaced by the CX 550) and Klipsch Custom 2.

Frequency response: 15–25,000 Hz
Sensitivity: 104 dB SPL/mW (1mW)
Nominal impedance: 16 ohms
Attenuation: up to 26 dB (95%)
Transducer: Dynamic driver

The C551 is similar to their high-end IEM, the AH-C751. While not as big, the C551 retains a similar bullet shape profile. Despite its look I was surprised by how light the headphones are. Like the CX 95, the Denon comes with an extension cable that terminates at a gold plated 3.5mm L-plug. The cords are well made and isn't as sensitive to microphonics as the one found on the CX 95, and is also less prone to getting itself tangled. Despite the good impression I found the Y-split and stress relief to be disappointingly fragile looking.



The C551's housing is made of machined aluminium, a nice change and premium compared to the sea of plastics favoured by Shure, Ultimate Ears and Sony. They are wonderfully engineered and looks prettier than the CX 95. In each of the earpiece lies a 11mm neodymium dynamic transducer. The large driver size meant that the canal body is a bit larger than the CX 95. This results in less isolation as I was unable to push the drive unit into my small ear canals. Despite that I had no problem getting a good fit and seal with the supplied silicone tips (which are interchangeable with Sony and Sennheiser headphones).

At the back of each earpiece are these holes that Denon calls Acoustic Optimizer, more commonly known by simple people as bass ports or air vents. These ports are said to provide the sound characteristic of the headphone by "adjusting the sound pressure balance in the front of and behind the diaphragm", whatever that means. Ergonomically they can be worn with the cords hanging down or over the ear style (for less microphonics). The Denons are not the most comfortable in-ear headphones I have worn, but they are also not the worse. Unfortunately they also leak plenty of sound, no thanks to the large Acoustic Optimizer vents.



Enough chatter, what about sound quality? Well they have a nice warm sound signature. Compared to my CX 95, I have to admit I much prefer the CX 95 (to be fair the CX 95 does have hundred of hours of burn-in/listening time to it compared to about 60 hours on the C551). The bass on the C551 for example hasn't got the same impact, though I did find the bass performance to be tighter. Regardless the bass performance is more than adequate for bass heads and fans of electronic genre.

The soundstage isn't as airy or wide as the CX 95, though that isn't saying much as all IEMs suffer from the same problem when it comes to imaging (except perhaps the IE 8). The sound quality overall is good but is a little harsh on the treble and the mids are a bit grainy. Details and definitions are also comparatively weaker to the CX 95. Overall the sound signature is dark with good mids but recessed highs.

Despite the C551 being only second IEM, Denon appears to have delivered a quality product. The problem here is that while the C551 is a perfectly fine quality product, there are better products out there (at least in my opinion) within the same price range. Sennheiser's CX 95 does seem to better them at almost every level, at least when it comes to sound quality and bass impact and mid-range. The Klipsch Custom 2 on the other hand offers delightfully lush mids with good highs and adequate bass response for a reasonable price.

The C551 is available for around £50 from Amazon UK.

Koss PortaPro portable headphone mini-review

Koss Portapro is one of the best loved portable headphone. Released in 1984, the Portapro has retained its initial classic goofy design since, even surviving the company's 1984 bankruptcy. It is still one of the best value headphones on the market and its strong following only proves it further. Even better the Portapro comes with a no quibble lifetime warranty.

Plenty of pretenders to the throne has come and go. The popular Sennheiser PX 100 is always compared to this supraural headphone as its primary competitor, but the design while pretty, isn't meant for everyone. The Portapro on the other hand is one of the most comfortable headphones I have ever placed over my head. The adjustable headband allows for any head size. You can also adjust the firmniss.



Frequency response: 15–25,000Hz
Sensitivity: 101 dB SPL/mW
Nominal impedance: 60 ohms
Transducer: Dynamic

Like many popular portable headphones, the Portapro can be easily folded. This makes them easily transportable when not in use. They do look pretty fragile, but the plastic does seem tough and capable of withstanding plenty of abuse. Then there's that no-question lifetime warranty...



The sound from this is amazing. Initially I found the mids to be recessed, but after burning them in a little while I found them to be sparkling. Treble extension is fantastic. I would describe the sound as bright with slight emphasis on mids and highs. All in all I find the sound quality to be equal to that of more expensive headphones like the Grado SR60.

Due to the nature of supraural headphones, you won't be getting much, if at all, isolation with this. Plenty of sound escapes, making the headphone not ideal for use in sensitive places like the quiet section of a train carriage.



Despite its sound quality, not everyone will like the sound signature. I know I didn't (I prefer more emphasis on bass). But if you like a good and cheap headphone with good all around natural performance across all frequencies, you will not be disappointed by this.

The PortaPro's retro look may not please everyone, but if you do decide to get one, they available for as little as £17.99 including shipping from Amazon.co.uk or US$35 from Amazon.com.

JVC HA-F130 GUMY earbud review

JVC's HA-F130, or more popularly known as GUMY, is an ideal replacement earbud for those seeking to replace their broken bundled earphones such as those that came with their iPods. The cost (less than £5) makes them even better value especially when compared to replacement iBuds.

Frequency response: 16–20,000Hz
Sensitivity: 108 dB SPL/mW
Nominal impedance: 16 ohms
Transducer: 13.5mm dynamic driver

The build quality is surprisingly good. The body is covered in what appears to be hard rubber or silicone. The cord is of a decent length and terminates on a straight 3.5mm plug. Unfortunately they tangle too easily. More importantly, unlike most other earbuds I've tried, they are also comfortable to wear for more than an hour.

The sound quality isn't too bad. In fact they sound pretty damn good for the price. Clarity wise, they beat the Sennheiser MX 300 I reviewed a while ago. The mids are rich but the highs, while detailed, is weak. The soundstage is airy, thanks to the pin size vent, which also means better bass impact. No where near comparable to the Sennheiser IE 8, but then again the IE 8 costs 40 times more!

For the cost of a lunch, I think it is stupid not to consider getting a GUMY as a backup headphone or something to use for exercise during when sound quality isn't a critical part of a headphone. They can be found at Amazon.co.uk, Amazon.com or any good supermarket.

Impedance (1kHZ): 18-ohm
Price: $79.99

It is available for pre-order from Amazon.com for US$79.99

Sennheiser IE 8 in-ear headphone review

The IE 8 is Sennheiser's flagship high-end in-ear headphones. With a suggested retail price of £263/US$450 (the street and online price is significantly cheaper) the IE 8 forms part of the upper end of universal fit in-ear headphones and is designed to compete with established products like the Shure SE530, Ultimate Ears Triple.Fi 10 Pro, Westone 3 and Klipsch Custom 3. Thie Sennheiser model is unique as it is one of the very few high end IEMs that uses dynamic transducers instead of balanced armatures. Also, among the IE series, the IE 8 is the only model to be fitted with a modular cable allowing the user to replace the cable with different lengths and stuff as well as a tune-able bass system.

Specifications and stuff:

Frequency response: 10 Hz – 20 kHz
Sensitivity: 125 dB SPL/mW (1mW)
Nominal impedance: 16 ohms
Attenuation: up to 26 dB (95%)
Transducer: Dynamic
Headphone weight: 5 grams



For your money Sennheiser ships the IE 8 in a nice tin metal case. Whether or not these are useful is debatable, but maybe Sennheiser thought a nice tin metal case would appeal to users who likes to feel 'premium' and pampered. Inside the box contains a a massive amount of accessories, some useful, some not so much. Various tips (single flange silicons, double flange silicons, Shure black olives-like foamies and bizarre ridge silicon thingies) are included, a tool with ear wax cleaner and screw driver (for the bass knob), shirt cable clip and memory wire holder (similar in function to the one on the Klipsch Customs but removable).

Also included is an over engineered protective case that is lined with 'dry salt pads'. These pads are said to 'control the humidity' of the case whilst also absorbing any sweats. May be useful for people who excercise with $300 headphones. The case itself, while nice and pretty, is overtly complicated for everyday use. I wonder how much time and R&D is wasted on this? They even designed a compartment so that the user can keep a silicon gel bag! Dear Sennheiser, a zipped semi-hardcase, like the one Klipsch bundles, is more than sufficient.



Now on to the IE 8 itself. My first impression is I thought it was a fake because of how light the overall package was. The IE 8 is like the Kate Moss of the IEM world especially when compared to the CX 95 and Klipsch Custom 3 which felt awfully heavy afterwards. Built quality seems to be good and the industrial design is a nice change from the streamlined design favoured by other manufacturers. The IE 8 uses a modular cable meaning that if you ever lose your cable or fancy a different length cable you can always order one from Sennheiser and just plug in the new one. It also means you do not have to purchase a whole new IEM just because the cable breaks. Not that you should feel worried as the bundled cable is thick, flexible and seems well constructed.

The IE 8 are pretty comfortable on my ears. I've read that due to the IE 8's design many has been experiencing problems getting a good fit/seal. The problem stems from the short nozzle/large driver body design which prevents users from pushing the tip all the way in. Klipsch cleverly avoided the same problem despite sharing a similar design by extending the nozzle where as with the CX 95, the problem is none-existent due to the slim driver body. On a personal note I am happy to report I've not experienced such a problem despite only using the medium single flange tips. IE 8 has always held securely onto my ears and does not dislodge despite doing silly faces and whatnots. However they do don't isolate as well as the Klipsch Customs with the silicon tips, though they are far less microphonics (in fact almost none-existent).



Like Sleek Audio's SA6, the IE 8 allows the user to customise the sound somewhat. But rather than using modular treble tips and bass ports which are easily misplaced, Sennheiser's boffins decided to engineer in a small knob that allows the user to control the bass response to something that is more to their liking. A small sound adjuster screwdriver-like tool is included for this. Personally I find the bass response to be more than adequate with the minimal setting but bass heads will no doubt love this feature and will take advantage of the knob the moment they can. I do turn it up a notch or two when listening to electronica music and find the bass beats are phenomenal. It feels like there are tiny subwoofers in your head.

The IE 8 has to be one of the most average sounding high-end IEM I've listened to out of the box. Like many IE 8 owners I found the initial bass response to be bloated and harsh. This is because unlike the Klipsch Custom series I reviewed in December, the IE 8 uses a single dynamic moving-coil driver which tends to require burn-in period before they shine. Leaving aside the fact that I personally think that Sennheiser should be the one doing the burn-in dirty work at the factory, I left the IE 8 to burn while listening to it at intervals. The upside of using dynamics is the wide frequency response and better bass response.



After just a couple of hours burn-in, the bass tames a little and the clarity improves. With further burn-ins, the IE 8 turned from an average sounding headphone to something that was well capable of delivering great midrange definition. The once recessed highs were blooming and the initial dark sound is all but gone, though they were still a little bit muddy. At this point I notice how vocals is one of the strength of the IE 8. They were clear and smooth. There were no issues with sibilance during my period with the IE 8, except perhaps with badly recorded music.

50 hours of listening later (I've stopped burning-in by then) IE 8's soundstage is simply astonishing - with depths unheard of in any IEMs I've ever owned/listened to. It makes for a pleasant change from the sound signature of more "inside-head" IEMs, like the Klipsch Custom 3, as this increases instrumental seperation. The clarity is amazing and while the resolution isn't nearly as detailed as the Custom 3, it is still pretty good. Even the highs improved, though still not nearly as forward as the Custom 3 or as extended as a Etymotic headphone. Mind you, both are very different IEMs. While the Klipsch has a very clinical sound, the IE 8 seems to be have a softer grainier texture with a wider dynamic range at its disposal.



If you do not require the bass knob or modular cable, then you should also consider the IE 7, the IE 8's slightly more svelte and cheaper Darth Vader-like cousin. Apparently they sound just as good as the IE 8 with the bass knob set to low. Even if the cable isn't replaceable, they ought to last long. Still the IE 8 is, at least for the moment, the pinnacle of dynamic transducer based in-ear headphones. They sound wonderfully like open headphones with amazing sound quality to match.

Perhaps the worse thing about the IE 8 is how they expose some badly ripped and low bitrate tracks, thus forcing me to re-rip some of my music collection - something that I should have done a long time ago if I weren't being such a lazy arse. With very strong and tight bass impact and extension, amazingly wide soundstage, strong lush mids and treble extension; combined in a thoughtfully light package, the IE 8 is without a doubt one of the best portable headphones you can buy today. Happy listening.

The good stuff
Open headphone-like soundstage
Good thumping bass
Lush mids
Very light
Modular cable
Good selection of tips
Standard two years warranty

The bad stuff
Fit may be an issue, this is one IEM you should try before you buy
Noise attenuation is less compared to other brands
Expensive
Lousy case
