Probably a dozen threads about this here. In any case, I have a Turtle Beach Z22 and very happy with it. It is not wireless and does require both a mini jack (for speakers) and USB (for built in amp and mic). Also has the little box in the middle for use with all the various dials controlling the amp, playback, mic, and VoIP. Some issues about Win8 by some people according to posts. But I never tried that last one. Dunno. Pretty sure the main difference with the PX is that the PX is more compatible with consoles. But if you want a console headset go away.

Yea the Z300 is the wireless version and is very expensive.
