I bought my first Bose Headset a little over a year ago and liked it so well that I bought this one for my oldest sons birthday.

There is nothing better. Just do yourself the favor, you wont regret it. When you buy quality, you only cry once... and these my friends - are proven quality. I held off for a really long time on purchasing these, mainly due to their price tag... but theyre worth every penny, and if you take care of them, they will last a lifetime.

I purchased a set of 3 for our BBJ with expectations of improved intercom and outside radio communications. I have used ANR and PNR headsets for a decade (different types), with and without blue tooth. This BOSE product with- bluetooth has been loved and complimented with superlative comments by all of our crew and contractors coming onto the airplane. These are a genuinelly superior product that brings noise reduction and superior sound. reproduction quality to the cockpit. International ops are enhanced (accents more understandable), and for those long silent periods, podcasts and music sound great... We all love these headsets.

The Bose A-20 is the best there is!

September 6, 2018


Q: Is the current stock of the Bose A20 headsets the newest version with Bluetooth music streaming and multiple Bluetooth connectivity?

Yes, all stock is the newest version with the upgrades to the Bluetooth connectivity.

Q: What is included in the box with the A20 headsets? Does it have the carrying case, any other accessories?

Here is what is included in the box: A20® Aviation Headset, In-line clothing clip, Control module, 2 AA batteries, Aux-in cable adapter, Carrying case

Q: Does this Bose A20 ANR headset with Dual GA Plugs have a dynamic microphone? With a Becker AR4201 transceiver, it appears a different wire harness is required depending on standard verses dynamic mic. Can you clarify.

No. This headset has an electret microphone which is used in general aviation applications. Dynamic microphones are used in military applications.

Q: On the non-bluetooth Bose A20 model, you can use the Aux Audio cable to listen to your music stored on you phone I believe. But can you also use this cable to make/receive a phone call?

PER BOSE - The headset does not support microphone operation when connected to a device via the AUX audio cable. Hold the device closer to your mouth to use the devices mic.

Q: Will the Bose A20 with Dual GA Plugs fit the fit AIRBUS 330?

We cannot say for certain whether this will fit the A330 aircraft. Some Airbus aircraft are outfitted with dual GA input jacks, in which case this headset will work. Some however, are outfitted with the XLR-5 Airbus style single plug, in which case, you will need to order part # 11-14326.

Q: My wife and I are flying both with the Bluetooth Bose A20 and she plays music on her device connected through Bluetooth on her headset, can I pair to that device as well so that we can be listening to the same music? Thank you

If the device you are streaming the music from can support Bluetooth to multiple devices, then yes, you will be able to stream to both headsets at once. For example, the Apple iPhone supports up to 5 simultaneous Bluetooth devices at once

Q: The literature on the Bose A20 states that there is the option of a straight or coiled cord, yet when I attempt to place an order Im not given the option to choose? Is that option available?

No, for the Bose Dual GA plugs style A20 with Bluetooth, there is no coiled cord option. This is available in straight cord only. The without Bluetooth version has the coiled cord option, please see part # 11-13772 for this model.

Q: Is this a stereo headset? Is the Helicopter version also a stereo headset?

Yes, the A20 series are all stereo headsets.

Q: Is Aircraft Spruce a Bose Authorized dealer?

Yes, Aircraft Spruce is a Bose authorized distributor.
