Can I listen to music or other audio wirelessly via Bluetooth?
Yes, the Bluetooth music experience is the best way to listen to music wirelessly and provides Bose quality sound. You can also stream warnings and alerts from your favorite apps. In addition, the A20 headset also has other Bluetooth profiles, including hands-free calling and multi-point, which allows you to connect to more than one wireless device simultaneously.
Do I need to do anything to optimize the performance of my headset?
No. The headset constantly adjusts to the noise environment and automatically optimizes the performance it delivers.
Why is TSO important?
A Technical Standard Order (TSO) is a minimum performance standard for specified materials, parts and appliances used on civil aircraft. When a company is authorized to manufacture a material, part or appliances to a TSO standard, this is referred to as TSO authorization. When a company receives a TSO authorization, it is assured that the product meets these minimums in both design and production. Bose Corporation meets all and exceeds many TSO requirements.
Can I comfortably wear eyeglasses and hats with the A20 headset without impacting the headset’s performance?
Yes. The earcups’ supple leather-covered foam cushions are designed to provide an effective acoustic seal even over glasses. You should be able to wear your glasses comfortably without significantly diminishing the headset’s noise reduction benefits. There is no need to calibrate or recalibrate the headset to maintain optimal performance. The headset adjusts automatically.
Does the A20 headset have auto-on or auto-off capability?
Yes, the aircraft powered version of the A20 headset has both auto-on and auto-off capability, so when the avionics have been turned on, the headset will turn on automatically once aircraft power is detected. Battery-powered versions of the headset have auto-off, but require that you press the power button to turn on the headset.
Can I convert my 6-pin plug headset?
Adapters are available from Bose to convert a 6-pin connector to either a dual G/A plug or a U174 for additional connection flexibility.
Can I switch the boom microphone from the left side to the right side?
Yes. The boom mic can easily be swapped from the left to right side (or vice versa) by unscrewing two screws and repositioning the mic onto the desired earcup.
Are original Aviation Headset X® accessories compatible with the Bose A20 headset?
Not really. While these cushions and parts may be forced onto the A20 Aviation Headset, they have not been designed or implemented for this product.
