New to the party but have owned dozens of different items at various price points. Recently traded my collection for a pair of Shure 535s & a pair if UE900s... I just don't get the fuss about the UE 900s - they're really not top tier next to 535s with the right tips. Are there many UE900 fakes about cos mine're really lame for the money?
I don't think you can really say that either outclasses the other in general. One is more technically superior while the other is great if you like a thick, gooey sound and love forward mids. Many would consider the UE900 leaps and bounds ahead of the dated SE535 with its very colorfully tilted sound signature. Some people just like one sound better than another... the UE900 are top tier, but maybe not to your taste.
