You can buy an A20 with a 5-pin XLR plug. Airbus uses it and apparently so does Embraer. Search for it on Amazon or Bose websites to see. It’s meant for the aircraft to power the ANR instead of needing batteries.
You can also buy an A20 with a GA two-prong plug, a 6-pin plug, or a U174 helicopter plug. There are adapters for some plugs into others. Most are to convert non-GA headsets to a GA plug since that jack is the most common in aircraft by far, at least outside the airlines or military.
