One of my TVs does not have Bluetooth functionality, so I purchased a Plugable Bluetooth 5 adapter for the attached computer. Including shipping and tax, it was $20.80 on Amazon.
This is a quality product. I plugged it in, it auto-installed its own software, and I then paired my earbuds with it. To use it, I turn on the earbuds. To use the normal computer audio, I turn off the earbuds.
Extremely simple, and excellent quality. And very small – you can hardly see it unless you get up close to the computer.
I highly recommend this product.
