You can try something like the Razer Megladons (which I have) but unfortunately I cannot guarantee that they'll work with your setup, as I'm having a little bit of trouble with mine. But the headphones do 5.1 and 7.1 surround sound, as well as normal 2.0 stereo.
P.S. It may just be my specific pair of headphones, as one of my friends also has the Razer Megladons and loves them as they work perfectly.
