Klipsch's Image X10 is easily the sexiest and smallest high-end IEM I've ever laid my eyes on. Unfortunately they are pretty expensive. Klipsch UK, in conjunction with What Hi-Fi? Sound & Vision, is offering the Image X10 for a slightly better price of £129.99 down from £179.99, the same price as the mid-range X5. The offer ends on 6 January.
Unfortunately for me and my wallet, I am all spent out. :( You can read my opinion of Klipsch's Custom-3 here.
