Bose A20 Headset Repair
Bose has ended out-of-warranty A20 service in the U.S. (see Bose's service page). We still repair them. If your A20 has intermittent audio, a microphone problem, a damaged cable, or an ANR issue, send it in and we'll tell you what it needs. Estimates are free, and nothing is repaired until you approve it.
What We Repair
- Damaged, frayed, or intermittent cables and plugs (dual-plug GA and 6-pin LEMO)
- Microphone and boom problems
- Audio faults and ANR problems
- Worn ear seals and microphone windscreens
- Cleaning and servicing
Not every fault can be repaired, and some depend on parts availability. If we can't fix it, we'll tell you before you spend anything on repairs.
Before Sending Your Headset In (Quick Checks)
These quick checks can sometimes save you time and shipping if the issue turns out to be aircraft- or setting-related.
- Verify your headset is in the proper mode (Mono or Stereo). Wrong mode = no right audio.
- Try your headset in a different position (copilot or passenger seat) to see if the issue follows the headset.
- If possible, try the headset in a different aircraft.

As a pilot and technician, I understand how critical clear and reliable audio is in the cockpit. Every repair is approached with that responsibility in mind. Read what other pilots say.
