Bose A20 Headset with coiled cable and LEMO plug for insertion into the panel connector of an installed wire harness. The Bose 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 ear cup 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 ear cups, providing an even quieter headset experience. The A20 aviation headset also provides a new level of comfort and stability. The overall headset profile is more compact, but the ear cup cavity has been enlarged to allow more room for the ears. These proprietary cushions improve the ear cups' acoustic seals, even over eye glasses, and remain comfortable during long flights. The solid magnesium headband is extremely durable, yet lightweight, and its sheepskin cushion eliminates hot spots. All these improvements have been achieved without increasing the headset's weight or clamping force. The A20 headset weighs just 12 ounces and exerts significantly less clamping force than most active headsets.
The redesigned control module now includes an auxiliary audio input with Intercom/AUX priority switching. Many pilots will want to use this input for dedicated GPS and traffic warning systems. You can set audio priority to mute the AUX input completely when intercom signal is detected, or to simply lower the AUX volume appropriately.
Smart power control
The power system in the A20 aviation headset includes a smart shutoff feature that helps provide at least 45 hours of use from just two AA alkaline batteries. With the installed version of the headset, the technology intelligently switches from aircraft power to battery power as needed.
For all types of aircraft
The A20 aviation headset is available in an installed, aircraft-powered version and in portable, battery-powered version
More Noise Reduction
Significantly improved noise reduction across a wider range of frequencies. Proprietary Bose innovations now use microphones both inside and outside each ear cup to sense and reduce more ambient aircraft noise.
Improved level of comfort achieved through choice of materials, distribution of weight throughout the headset, 1/3 less clamping force than most conventional noise reducing aviation headsets, and additional room for the ears.
TriPort acoustic headset structure, available only from Bose, produces tonally balanced audio from relatively small and lightweight headphones. Active equalization electronically tunes the headphones' frequency response, enabling outstanding audio performance.
Significantly greater noise reduction - you'll be amazed at how quiet the A20 headset is!
Improved level of comfort - 1/3rd less clamping force than most other aviation headsets.
Clear audio - famous Bose quality is evident in both the speakers and microphone.
Auxiliary audio input - so passengers can listen to music.
Priority switching - you decide which audio source you want to hear.
The ergonomic control module features independent volume controls. Runs for over 45 hours on just 2 AA batteries. Weighs just 12 oz., includes carrying case, five year warranty.
