Turns out the Bose headsets I recieved as a gift from a friend who is no longer flying are the X model instead of what I thought all along were A20s.
Replaying the conversation it probably went like this:
Him: here's some Bose headsets
Me: Awesome, thanks! Are they the A20s?
Him: ...uh, yeah I guess (hands me headsets)
Funny thing is I've ordered replacement ear caps and padding assuming A20s and everything fit so far.
Long story boring...the A20 bluetooth is back on the market for 100.
