There is a review of Corsair's Void Pro RGB USB headset posted today over at techPowerUP! that I think all of you should check out.
The main difference between them has to do with connectivity. While the Void Pro Surround comes with a USB sound card, but can also be used in analogue mode, the Void Pro RGB USB only has a USB connector. As such, it can be plugged into the PC and nothing else - console gamers should stick with the Void Pro Surround.
