USB Gaming Headset for Mac

I am looking for a Gaming Headset that is compatible with Mac. I have a MacBook Pro Retina.

- USB
- over the ears
- 7.1 sound
I have looked around and most good gaming headsets dont run on mac or they don't have software. I just want to be able to plug and play.

I like these ones but im not sure how they will work on the Mac. SteelSeries - Gaming Headsets - SteelSeries Siberia v2 Frost Blue

According to Steelseries' website, that headset is Mac compatible.
