My favorites have been Westone UM2's (with the Shure "black foamie" tips, but now the Westone 3 has just been released (in the past couple of weeks).
I've got a pair of Westone 3's at home and they are just a bit more neutral top to bottom, more extended in the treble while still refined, and more detailed in the bass while still very deep in bass.
Overall it seems a very noticeable incremental improvement top to bottom, while retaining the very natural and musical family sound.
I've tried almost everything out there and I think that for the audiophile who is sensitive to natural and refined sound, the Westone 3 or UM2 are best.
Also Westone seems to make the most comfortable in-ear earphones, which is a MAJOR issue for many people with these types of phones.
