This headset is excellent for gaming, the sound is so great and I remember when I was a kid playing CS Source, I could hear the footsteps of the enemy team in the other end of the map, which exposed their position, so I was always ahead. When you first put them on, you almost can't hear anything except the sounds from the games you are playing or the music you are listening to, the isolation is just great. It has a mic which you can pull in and out, so it is not in the way, when you aren't using it. It comes with an extender, so the cable length won't be a problem.
Here is a little review of it! http://www.tweaktown.com/reviews/4891/steelseries_siberia_v2_usb_gaming_headset_review/index.html

"The siberia v2 doesn't only feels great to wear and hold, but is one of the best sounding options for the price"
