Did you listen to them at, say, Best Buy or with a rig your with which you are familiar? They were on sale for a killer price when I got them and while they were in transit, I went to BB to give a listen and regretted my purchase immediately (the only 'phones that sounded even half-way decent at the store were the UE600s). They arrived and I decided to give them a chance. It did take a while for them to break in and after they did, I found them quite natural sounding with remarkable clarity - no harshness or plasticky sound at all. As xlin6 staded, they really come to life with an amp. The only thing I do not like about them is that, even though they are "closed", they pick up ambient noise (like you find in an open office environment) and that noise sounds like holding seashells up to one's ears. This goes away once the music starts and/or in a quiet environment.
Of course, it all boils down to personal preference, which makes this hobby so much fun! :wink_face:
