Bose was first to introduce active noise reducing headsets to aviation more than 20 years ago, forever changing the way pilots fly. Now, the Bose A20® Aviation Headset introduces an entirely new standard by being the most technologically advanced Bose® headset ever. Engineered for significantly increased noise reduction, the Bose Battery Powered ANR A20 Aviation Headset w/Bluetooth performs in even louder environments -- without compromising the clear audio you expect from Bose. In fact, the Bose A20® Aviation Headset boast an average of 30% greater noise reduction than conventional noise reducing aviation headsets. The 12 ounce A20® Aviation Headset provides an improved degree of comfort you'll appreciate. The improved level of comfort is achieved through choice of materials, distribution of weight throughout the headset and a 1/3 less clamping force than most conventional noise reducing aviation headsets. Plus, a Bluetooth® communications interface, auxiliary audio/music input and priority switching. It's made in the U.S.A., and meets or exceeds all TSO requirements. No other headset can deliver this advanced combination of benefits. < h2>
