The ones Ment mentioned are rather nice, but I found the ear-pads a bit uncomfortable and it didn't fit my head all that well. Seeing as I use my headphones for everything, I ended up having to get another pair.
PLANTRONICS .Audio 350 3.5mm Connector Circumaural Over The Head Stereo HeadsetThey're nice and big, fit comfortably over the ear and are pretty sturdy. About my only complaint is that I've had a couple pair go bad due to breaks in the wires. Which was ultimately my fault.

The cords are so long that I always seem to roll over them with my chair at some point. I fixed this by keeping the excess twist tied and hung from below my desk.
I think there's a USB pair as well, but the the only version I can find on Newegg is the
PLANTRONICS GAMECOMPRO1 USB Connector Supra-aural Gaming Stereo Headsetwhich is a bit expensive. Nice, but expensive. I'm fairly certain I saw the other version in USB format when I went to pick up my most recent pair (though it was a few bucks more).
