I've never used bluetooth headphones so I'm no help there.
Does any of the 4 entries I see ever show connected when plugged in?
If so, right click the entry and select "set as default". Then the sound should come through the headset and not the in built speaker.
HI, Liz,
I can't "set as default" as the setting is 'greyed' out. It became obvious that it was "SOUND" (Device Manager) files that may be corrupted.

(Did a various of things which at this moment can't remember the 'command' to un-click Media, etc, restart, then 'click' Media ... laptop sound speakers (lousy) back on).
'Change Sound Settings" --- see original attachment. Same problem - greyed out. I'm going to get my refund for these
speakers . I could purchase a pair of wireless headphones (BRV-Mini speakers in Device installed with a headphone icon instead of a speaker icon) to see if problem persists in "SOUND" but due to this plandemic, no return policy for headphones! (Note, Icon in "SOUND" is Headphones not speakers! - If I try with a pair of wireless headphones and it's works, I can hear via headphones, then Wireless Speakers s.w. installations was faulty but I won't be doing that ) Thanks for replying.

Suggested by a commenter :
The adapter that I'm using, USB dongle connected to the computer is:
Cirago Bluetooth Adapter Model: BTA-3210, (About $15 at NEWEGG)
It comes with The Bluetooth Stack software V2.1
Maybe I need to exchange the USB "Microsoft Wireless Transceiver" ? I'll ask the Computer Services Department Tekkie tomorrow about this !
