Misinfo, that u320 is a stereo headphone for computers. If you want surround with a console, your options are the two receivers Mad mentioned, Astro Mixamp, Turtle Beach DSS ($30), DSS2, or the control unit that comes with a TB ear force seven, Tritton AX720+ base station, PLYR 1 base station, or Creative Recon3D USB (which is also a credible soundcard for PCs).
Personally I own a DSS, Mixamp 5.8, and a Recon3D USB, I like the recon best with a tube amp plugged into the headphone jack.
They have some surround..they don't just sound like a stereo headphone..i agree ecjcc should get some sort of surround sound unit.. I use the rdac because it's got good positional audio with a decent size sound stage.. sennheiser hd 558 and a mix amp or a dss1 or 2 would do him!
