noise-cancelling headphones

Good clean loud if necessary sound but the headband is somewhat difficult to adjust plus the major flaw is the microphone. The mic doesn't seem to be amplified at all, low quality, whatever I had to adjust the Mic input to the max in XP to get it to pickup anything. Also I took apart the mic as well, the design is somewhat off, foam covering glued on one side, the other side had a removable foam filter covering the mic. The problem I notice was the foam was compressing the mic preventing it from picking up sound very well. I left the foam piece out. & after putting it back together the mic performance was fine. But be aware the mic signal seems to be pretty low. I tried running the mic through a Belkin KVM with nothing but static being picked up. With the mic hooked directly to the sound card along with the modifications it worked ok.

Uncomfortable, below average microphone, decent sound...
Bass and treble is decent, but nothing extraordinary.
These headphones are BIG and the headband can be a bit uncomfortable -- especially after long use.
The microphone [is bad]. I played a few PC games using these headphones and almost no one could hear what I said (yes, all my PC settings were correct).

I wouldn't recommend these headphones. Look elsewhere.

these are pretty normal. The mic works great. By looking at the headphones you'd think that they'd be killer for multimedia and have a lot of bass and stuff. They don't. Even though they're huge, their pretty comfortable and they've got decent volume. The cord is long which is important when they have to reach behind your computer so you don't have your forhead pressed to the monitor.
