BOSE A20 / Specifications
Significantly improved noise reduction across a wider range of frequencies. Proprietary Bose innovations now use microphones both inside and outside each earcup to sense and reduce more ambient aircraft noise. 
Redesigned ear cushions deliver greater comfort using new materials. More compact earcups now have a larger interior cavity, allowing more room for the ears; redistribution of headset weight also helps improve overall comfort and stability.
Bluetooth phone connectivity lets you take calls wirelessly through the headset.
Auxiliary audio input on redesigned control module for connection to GPS and other devices.
Smart shutoff helps provide at least 45 hours of use from just two AA alkaline batteries.
Enhanced center torsion spring on magnesium headband provides a consistent, comfortable fit for any size head—with significantly less clamping force than most pilot headsets.
Active equalization electronically tunes the headphones' frequency response, enabling outstanding audio performance.
Five-year transferable limited warranty covers parts, labor and second-day return shipping expenses for non-abuse malfunctions.
