A20® Aviation Headset with dual GA plugs, Bluetooth®

  • High impedance (electret) microphone for use in most GA Aircraft
  • Designed to deliver significantly better noise reduction in even louder environments
  • Provides greater comfort and stability, with more room for your ears
  • Auxiliary audio input for GPS and other devices
  • Bluetooth® mobile cell phone connectivity

The Bose® A20 Aviation Headset is our 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 and Bluetooth® phone connectivity.

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 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 340g 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.

Bluetooth® mobile phone connectivity allows you to receive calls wirelessly while wearing the A20® headset. And its enhanced EMI protection helps minimise interference from the mobile phone. Plus, the headset's integrated sidetone provides a more natural feel to Bluetooth® phone conversations, even when you're disconnected from the intercom.

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 versions for various craft, including helicopters.

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.

Redesigned ear cushions deliver greater comfort using new materials. More compact ear cups now have a larger interior cavity, allowing more room for the ears; redistribution of headset weight also helps improve overall comfort and stability.

Enhanced centre torsion spring on magnesium headband provides a consistent, comfortable fit for any size head — with significantly less clamping force than most pilot headsets.

Adjustable powered microphone can be connected to either ear cup and set in a range of stable positions for optimal communications.

Auxiliary audio input on redesigned control module for connection to GPS and other devices. Pushbutton Intercom/AUX enables priority switching.

Bluetooth® phone connectivity lets you take calls wirelessly through the headset.

Enhanced EMI protection to minimise communications interference.

Integrated sidetone for more natural sounding intercom and mobile communications.

Smart shutoff for extended battery life. Installed headsets also feature a flexible power system to automatically switch from aircraft power to battery power as needed.

Ergonomic control module has been redesigned for greater ease of use. Includes contoured grip and streamlined interface with high-contrast icons on main controls.

Custom carrying case helps protect headset during storage and transport.
