Bose Headset A20
The Quietest, most comfortable headset available! Proprietary technologies in the A20 aviation headset reduce more noise than ever before, across the full spectrum of human hearing, in even louder environments. Advanced electronics now use microphones both inside and outside each earcup to sense and reduce more ambient sound. Improved Bose® ear cushion technology helps further reduce unwanted noise. New cushion materials block more sound before it enters the earcups, providing an even quieter headset experience.
