i just got a pair of these a few days ago.
here is a mini review:
- they're bigger than i expected. coming from my logitech headset, they completely cover my ears and then some
- very comfortable. despite being bigger, they didnt feel heavy. and i actually prefer them much more than my old logitechs
- sound is ok. nothing spectacular.
- cord is ok i guess. the shielding thins out as you get closer to the plugs, so i take extra care not to yank too hard
- volume control/mute.. kind of lacking. feel cheap and i much prefer the logitech setup that used a large, flat dial.
overall i think they are pretty good. i havent tested the mic yet. from the few hours i've worn them, i had no ear fatigue since they are so huge and dont 'sit' on my ears.
