High-performance wireless gaming is here! Using optimized technology, the Xbox 360 Wireless Controller lets you enjoy a 30-foot range and up to 40 hours of life on the two included AA batteries - and when they run low, you're given ample warning so you can connect a Play & Charge Kit for uninterrupted play. Plug the Xbox 360 Headset into the controller for full two-way voice communication: a wireless first.
