Bose® Headset A20 6 Pin to Helicopter Adapter

What people may miss is that the panel powered Bose A20 (Lemo plug type) headsets have a spot in the volume control box for 2 AA batteries so you can use this adapter and it will get its power for the ANR. This adapter can only be used for a Bose A20 headset not older models.
