I'm very happy with my current Westone 3's, but just found out that M***Drop just added the Ultimate Ears UE900's, which I have always been curious about.
I know that sound wise, UE900's are more neutral with less of a V-shaped EQ than the W3's. How are the isolation and comfort? The W3's takes me about 30 seconds to put on, and while it gives very good sound isolation (using Comply P-series tips) it starts to hurt my ears after 4-5 hours or so. I hear that the UE900's are more comfortable, as they allow for a deeper insertion (the W3's tubby shape and short tips gives me some trouble regarding this), but how is the isolation using its own equivalent Comply tips?
