Logitech Wireless Headset H800. Chat, rock and surf—with no wires to tie you down. Easily connect to and switch between devices like your PC, tablet and smartphone with on-ear controls. Laser-tuned drivers and a built-in equalizer give you rich digital stereo, and a noise-cancelling microphone reduces background noise. Roam up to 12 m (40 ft.) from your PC using the tiny nano receiver—or pair with your smartphone or tablet using Bluetooth. The six-hour rechargeable battery lets you listen and chat longer, while a padded headband and ear cups keep you comfortable—and your headset folds like sunglasses for portability.
