I just got some Westone UM1s purchased on Bay for 96.00 shipped (not bad). They don't have major "thump" but they have decent low end and a very crisp, detailed sound, and lots of headroom for volume. I wasn't looking forward to using the foam tips but they are very comfortable in the ear and they reall stay put without much fuss. I may switch to silicon tips. I understand the Ec3,4 and 5 tips are compatible but if I had to stay with the foamies, I'd still be happy. The cord quality and length is perfect. Hopefully, they'll warm up a tad but overall I am very happy with them. In pictures they have a similar form factor to E2c (which I returned) but they are much more comfortable, seem less bulky and have a better sound...to me.
