haha! after that last arguement from the last thread you made another one. he'll be mad now.
i used the dt660 before, which should have very much similar design. first off the general consent about these headphones is that they are bright. to me, quite bright. the dt660 was very easy to drive, not even needing an amp to sound good out of my archos hd player, which has week output. their earcups are big, 4inches in diameter, and weights quite a bit as well. they are very comfortable to wear, just could be lighter. people concern about breaking the headband, but i just loosen the two screws on it and didnt get any problems.
i would not qualify them as portable, but they work sound good with portables, and i wear full size headphones in public anyway.
