Features

  • Significantly improved noise reduction across a wider range of frequencies. Proprietary Bose innovations now use microphones both inside and outside each earcup to sense and reduce more ambient aircraft noise.
  • Redesigned ear cushions deliver greater comfort using new materials. More compact earcups now have a larger interior cavity, allowing more room for the ears; redistribution of headset weight also helps improve overall comfort and stability.

  • TriPort® acoustic headset structure, available only from Bose, produces tonally balanced audio from relatively small and lightweight headphones.

  • Adjustable powered microphone can be connected to either earcup 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

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.)

Please note, Pilotshop.com's personnel are not certified aircraft mechanics and can only provide general support and ideas, which should not be relied upon or implemented in lieu of consulting an A&P or other qualified technician.

Any product eligibility information provided here is based on general application guides and we recommend always referring to your specific aircraft parts manual, the parts manufacturer or consulting with a qualified mechanic.

Q: Does the Bose A20 lemo version allow ANR to run on batteries if used in a Dual GA airplane? Can you confirm that the version you sell in fact does have AA batteries, and can be used with a dual GA setup just through a dual GA - lemo adapter (passive)?

Yes, the battery box for the Lemo version of the Bose A20 will accept the included AA batteries. This will allow the batteries to power the ANR if the headset is being used in a Dual GA equipped aircraft with passive adapter part # 11-08741. No additional battery box is required.

Q: Can the Bluetooth feature on the Bose A20 headset stream both music and phone calls or is it for phone calls only?

Yes, the Bluetooth feature will stream both music and phone calls to your headset from your device (ie, iPhone, iPad, Android, etc).

Q: What does the six pin lemo plug mean?

Six pin Lemo is the connection plug style. This type of plug is a single connector, and uses aircraft power to activate the ANR. This differs from the more common dual GA plug style, in which there are two male plugs that go into the aircraft jacks and requires AA batteries to run the ANR.

Q: With an A20 headset, LEMO style connector, will all functions, bluetooth etc.work without batteries in the control module? In other words, are the batteries totally unnecessary? If so, should I just keep it empty or will it default to the batteries if they are present? Any reason to use batteries as long as I am using a LEMO receptacle?

The batteries will only be used in the instance that the LEMO connector stops supplying power. The headset will always use ships power if available, and resort to the batteries as a backup. They can also be used if an adapter, Part # 11-08741, is used to use the LEMO Style headset in a airplane equipped with dual GA female jacks.

Q: Regarding Part# 11-13776: How long is the coiled cord and how springy is it? Would be nice not to have to lay the cord around out of the way...

Unstretched the coiled portion is approx 14-75 inches. It can be stretched over 6 feet.

Q: I have the Bose A20 Headset and my aircraft has the GA plug but also has the ANR power plug. Im wondering if there is some adapter that would allow the headset to be run without batterys. LEMO plug to some adapter perhaps?

You would have to change the cable to our part number 11-08734, for it to run off ships power.
