U.S. ARMY Tomahawk Wireless BT Over-Ear Headphones

I purchased two of these and could not get either to connect with Windows 10 or Android.
I am a pretty technical person and found the documentation to be horribly written.
It is as if a computer translated the directions from some other language.
How are these headphones put in discover mode?
Why are none of my bluetooth receivers picking them up?
What version of bluetooth are they?
Why does the documentation not mention there is a wired connection for standard headphone usage?
