Bose® QuietComfort® 2 Acoustic Noise Cancelling® Headphones

These exceptionally comfortable headphones offer full-spectrum noise reduction along with renowned Bose audio reproduction-the result of years of research and development. The headphones reduce office noise, the clatter of commuter trains, or the effects of airline engine sound during flight-all while delivering the crisp, true audio for which Bose is famous. Research studies have confirmed a link between noise, human fatigue, and symptoms of stress, proving that noise levels may severely affect the way you feel. The headphones are streamlined for more convenient travel, the earcups fold flat for better portability, and the on/off switch is on the earphone itself for easier activation. Improved noise reduction and audio performance results in lifelike sound and full bass without the artificial enhancement of "bass boost" found on most headphones. Soft ear cushions increase the comfort of wearing the headphones for extended periods, and each ergonomically designed earcup swivels into position to fit the ear. Includes carrying case, 5' extension cord, and adapters for airline audio jacks and home stereo. Requires one AAA battery for 35 hours of use. 7 3/4" H x 6 1/2" W. (7 oz.)
