Q: I have the Bose A20 with a Military single plug. Need an adapter to plug into an Airbus.
A: This is not the right solution.
You can do it in two different ways:
1. (preferred) Replace the cable assembly on your Bose A20 with the Airbus Cable Assembly. This allows you to use the headset with adapters and also the added bonus of Bluetooth.
2. Convert from military to civilian with the low to high impedance adapter. Then convert from dual plugs to Airbus with this adapter.
Q: Can I use my military headset with it?
A: No. This will not convert a military headset. Are you trying to convert military to an XLR-5 for Airbus? What military headset do you have?
