The Tritton Warhead was made in true partnership with Microsoft, and is the first naturally wireless headset for the Xbox 360 -- no dongles and no wires needed. It features 50mm neodymium drivers, two hot-swappable battery packs, and functions on the 5.8GHz band. The headset offers 7.1 Dolby Headphone, and the base station is powered by a single USB cable from the console. In addition, the base station can charge batteries while the console is off, and has optical and auxiliary inputs.
