Comfortable, wireless headset lets you chat, rock and surf on multiple devices like your PC, tablet and smartphone with rich digital stereo, a six-hour rechargeable battery and a full set of on-ear controls. Laser-tuned drivers and a built-in equalizer deliver rich digital stereo that immerses you in your music and calls. The noise-canceling microphone reduces background noise. With 2.4 GHz wireless technology, roam up to 12m (40') from your PC using the tiny nano receiver or pair with your smartphone or tablet using Bluetooth. Listen and chat longer with up to six hours of battery life on the rechargeable battery. Position the microphone right where you want it or rotate it up so that it discreetly hides in the headband when you're listening to music or watching a movie. Lightweight headset folds up like sunglasses when you're ready to hit the road. Wireless Headset H800 includes a nano receiver and USB recharging cable.
