Enjoy a peaceful,
comfortable flight

The A20 headset gives you 30% greater noise reduction than conventional aviation headsets, so you’ll enjoy a peaceful flight from short stops to long hauls. And at just 12 ounces, with sheepskin cushions and minimal clamping force, it’s one of the lightest and most comfortable aviation headsets you’ll find. All designed to let you focus on what matters—flying.
   

Clear audio for music and communication

Bose Active EQ keeps the audio clear and distinct, whether you’re listening to music or an important communication.
Simple, intuitive operation

Plug-and-play convenience means the headset is ready to fly when you are—no need to press a lot of buttons first just to activate it.
   

Enhance your experience

The ergonomic control module includes an auxiliary audio input with Intercom/AUX priority switching, ideal for dedicated GPS and traffic warning systems. It also features a customizable audio prioritization control with “mute” and “mix” settings, and flexible power circuitry with auto-on that switches to and from battery power and aircraft power. Select models also include Bluetooth connectivity for taking calls or listening to music.
   

For all types of aircraft

Features

  • 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.
  • TSO certified by FAA/JAA to meet performance standards for headsets used on civil aircraft. Made in the US, it also meets RTCA/DO-160D and DO-214 environmental requirements.

Ive had this headset for 5 years now so I feel confident saying......why did I wait so long! These things do everything to make communications clear and easy to understand. The bonus is using them to watch movies using the Bluetooth while riding in the back on the way home. Buy them...you wont regret it!

I wish I had bought these years ago. Been using a competitor but needed new headsets for the rear seats, so thats where those will go. In direct comparison, the A20 has a longer mic that reaches to front of your mouth, has a heavier duty cable, two clips to clip it out of the way, no fuss bluetooth connection, way better ANR without annoying occasional pressure waves, the control just feels right in your hand, and way easier to store away in the zip case.

Bose makes a very comfortable headset with great ANR capability. Passive noise protection is very limited, so always keep fresh batteries with you.

Ive been using Bose in my personal aircraft for seven years. Nothing compares--costs more upfront, but worth it in the long run. Aircraft Spruce is super reliable in shipping, packing, and always competitive in pricing (although there is no competitive pricing allowed for Bose.)
