• Provides greater comfort and stability, with more room for your ears
• Auxiliary audio input for GPS and other devices
• Meets or exceeds all FAA and JAA TSO requirements

The Bose® A20 aviation headset is the most advanced pilot headset yet. Its breakthrough innovations reduce more noise and provide even greater comfort than previous models, without compromising the clear audio you expect from Bose. Plus, the A20 Aviation Headset now includes auxiliary audio input.

Next-generation pilot headset
More than 20 years ago, Bose introduced active noise reducing headsets to aviation—and launched an entire industry. Year after year, pilots have made our headsets their #1 preference. Now, the A20 aviation headset introduces an entirely new standard.

Enjoy a quieter flight
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.

And even greater comfort
The A20 aviation headset also provides a new level of comfort and stability. The overall headset profile is more compact, but the earcup cavity has been enlarged to allow more room for the ears. These proprietary cushions improve the earcups' 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.

AUX IN and Bluetooth technology convenience
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.

The A20 aviation headset features greatly improved noise reduction across a wider range of frequencies
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 and improved stability
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.
