I did not order the Bose A20 Headset because you do not accept American Express Credit cards. I purchased and received the headset from another supplier .

Wow, Bose’s latest is considerably better than the 8 year old ones originally purchased for my wife, which I would use when solo. So quiet I strain to hear the familiar and reassuring engine noise. Bluetooth connected painlessly to my iPhone. Earcups seem to be bigger, fitting better over my ears. Painful kilobuck purchase, but once over that, flight is now so much better.

Great product! I not only use this in my plane but also in my office for important phone calls and inside my heavy equipment. It cancels the noise and I listen to music while the equipment is roaring away.

As always, a very quick delivery of my order from Aircraft Spruce brought me the finest aviation headsets made. Very quiet, good audio quality and you almost forget your wearing them because of the comfort they provide. The gold standard for over the head communications in aviation.

Ive used the Bose A20 headset (with Bluetooth) since (I think) 2009. I have been extremely satisfied with these headsets. Very comfortable on long x-countries. Excellent audio. Do need to reset default to battery off after disconnecting from aircraft jacks. Otherwise, the headset remains on and batteries will get weak. But thats an easy reset. I have three sets of Bose A20s for my airplane and they are the best as far as Im concerned.

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.

Q: Is the ANR effective during operation of two cycle advanced ultralight aircraft?

Yes, the noise reduction will be effective in most aviation environments. The noisier the engine, the less effective it will be but there will always a reduction in the noise.
