Granted I'm not an audiofile. I woudn't know an ohm from an impedance, nor a hertz from a watt.

BUT

I use these mostly for late-night gaming and they are really comfortable. I've had them for a long time and they feel great. Even under stress the sound doesn't brake and music feels natural.
I remember these weren't so expensive, about mid-range, so looking back I'm very happy with the purchase.

If you're thinking of buying them used, you should check the sliding hinges on the earphone cups. They seem to be the weakest structural point....

P.S. I"m not sure why I didn't give them a perfect ten. Maybe if the cushions were leather... :)
