i basicly went through all of the beyer models to try a while ago. if you enjoy them, good for you but to me, beyers signature sound is something i cant handle. there were 2 cans i enjoyed for what they are, wich is the 32ohm 770pro and the 600ohm dt880 but all the others i dont like at all. including the 900pro x. dt990pro are prob among the worst, their treble basicly rapes ears.

Sennheiser HD6xx and HD560s i prefer in pretty much every way
