I must say, my crappiest pair of cans are a the Sony MDR-7506. Not only are the eap pads falling apart, but they just sound butt nasty. I bought these things a few years ago thinking if they are good enough for studio use, their good enough for me. Yeah, right! No bass, thin and distant midrange, and harsh treble. Maybe these are the cans Madonna's producers are using now! lol
On the other hand, my Sennheiser HD600's are the cream of the crop!
