The TRITTON Warhead 7.1 Dolby Wireless Surround Headset is a truly wireless Xbox 360 surround sound headset - no need to connect a chat cable to the gamepad. 5.8GHz wireless ensures interference-free operation from other 2.4GHz wireless devices and provides crystal-clear audio at a range of 30 feet. Immersive, high-fidelity 7.1 Dolby Headphone surround sound is fed through a pair of precision-tuned 50mm speakers with Neodymium magnets. Including two rechargeable battery packs for 24/7 gaming, one battery always charging on the base station means you can simply swap batteries when you need more juice. Adjust your game volume and chat volume separately on-the-fly, or choose one of three EQ settings to optimize your audio experience. Easily enable or disable the ability to hear your own voice through the headset with Selectable Voice Monitoring (SVM).
