Acclaimed noise reduction even in loud cockpits

Take a closer look at the most technologically advanced Bose headset yet
Innovative noise reduction

We created our active noise reducing headsets specifically with pilots in mind. They’re engineered to neutralize the distractions and stress of cockpit engine roar. For the A20 Aviation Headset, we’ve improved noise reduction and made a more comfortable fit. We’ve done this without compromising the clear audio you expect—and need—to focus on flying. Plus we included an auxiliary audio input and Bluetooth® phone connectivity.

Proprietary technologies in the A20 Aviation Headset reduce noise across the full spectrum of human hearing, even in loud environments. Advanced electronics use microphones inside and outside the earcup to sense and reduce ambient sound. Bose® ear cushion technology helps further reduce unwanted noise. Innovative cushion materials block sound before it enters the earcups, providing an even quieter headset experience.

Comfort for the long haul

Comfort for the long haul

The A20 Aviation Headset also provides significant comfort and stability. While the overall headset profile is compact, the earcup cavity allows plenty of ear room. The proprietary cushions provide quality acoustic seals, even over eyeglasses, and remain comfortable during long flights. A center torsion spring on the solid magnesium headband exerts minimal clamping force while staying extremely durable. Weighing only 12 ounces the A20 headset is lightweight and its sheepskin ear cushions eliminate hot spots. Keep them safe and protected in their included custom carry case.

AUX IN and Bluetooth® technology convenience

The ergonomic control module includes an auxiliary audio input with Intercom/AUX priority switching. Many pilots will want to use this for dedicated GPS and traffic warning systems. You can set audio priority to mute the AUX input completely when an intercom signal is detected, or to simply lower the AUX volume appropriately.

On select models, Bluetooth mobile phone connectivity allows you to receive calls wirelessly while wearing the A20 headset. And its enhanced EMI (Electromagnetic Interference) protection helps minimize interference from the mobile phone. Plus, the headset's integrated sidetone provides natural sounding communications when you're on a call and disconnected from the intercom.

AUX IN and Bluetooth® technology convenience

For all types of aircraft

The A20 Aviation Headset is available in dual plug, 6-pin plug and U174 plug models designed for use in all types of general aviation aircraft, including helicopters.

The 6-pin plug model has a flexible power system for increased versatility using custom adapters. When connected to the optional dual G/A plug adapter, it seamlessly converts your aircraft-powered headset to a battery-powered unit—ideal when taking your headset from one plane to another. Similarly, you can connect the 6-pin plug to the optional U174 adapter to use the A20 headset in helicopters, too.
