Kirkland 10 Bluetooth connection to my Mac

I’m trying to connect my Kirkland Signature 10 hearing aids to my iMac. I can make he conneciton, but it doesn’t last. It automatically disconnects. When I try to reconnect, the message is that the connection was rejected.

Are there an known issues with pairing these hearing aids to a Mac’s bluetooth? If it can be done, can you use the aids as your microphone as well?

It works great for me for everything except zoom/google meet. At first I did my calls using a voice call to join the meetings for that part. It worked ok. Then I bought an extra tv adapter and the toslink audio output for the USB port. Rock solid now. Uses the Mac mics for my voice and the system sounds go straight to the HAs.
