As a companion to the thread where this was discussed http://www6.head-fi.org/forums/showt...+Westone+ER-4p Which would you choose? Any other buying advice? After a lot of research and asking I am still on the fence. I suppose one ploy is to try to audition the etys, or buy them and return them if I don't like them. I think the UM2s would be hard to audition in Washington DC (only one good store with headphones). Discussion of the sound would be more frutiful on th other thread, probably.
