Interesting review. So W4 bass is significantly weightier and stronger than UE900. Yet many still think W4 is bass lite. Yet UE900 bass is significantly weightier and stronger than 4.Ai? That would seem pretty anemic to me and yes I consider Etymotic anemic. The lack of bass would certainly be a deal breaker for me on 4Ai. No interest...
