I use a "real 5.1" Rokkat Kave. Wired. Audio qualiti is not bad at all. Volume knob, microphone, and real headphones so ppl around you won't be disturbed. Mic can be placed our of the way when not in use. I'd recommend it. Or couse, you can use it as a "simple" stereo, if you wish.

Now, I don't find 5.1 particularly good or beneficial in any headset i've tried, but stil, it is available if you ever need it.
