Using a Fighter Pilot Helmet as Headphones.

I use adapters to turn my 1960’s fighter pilot helmet into headphones. I use it with a handheld radio (not transmitting only listening), an early 2000’s MP3 player, and show how I use it to play on MSFS in VR.
Adapters used:
MG-14 to GA: marvgolden.com...
GA to TRRS radio adapter: www.mypilotsto...
TRRS to TRS: a.co/d/cquwZHC
I’m sure there is a better Easier way to do this but, this is what I had on hand to play with.
