Mad Catz has announced that it has shipped the Primer wireless headset. Sold under the Tritton brand, the stereo headset is notable in that it is the first officially licensed wireless headset for the Xbox 360. Nearly identical in appearance to Tritton's Detonator headset -- minus the cables, plus a "base station" -- the Primer utilizes 5.8GHz wireless tech, which purportedly cuts down on interference from appliances, phones and the like.

It's also worth noting that it will work only with the Xbox 360, so keep that in mind before plunking down the $100 asking price.
