Soundcore q20 Mac not playing sound after power off and on

I have an M1 Mac. I can pair the q20 without issues. But, after I power off the headphones and power them back on the Mac will not play sound through them and I have to repair them for the headphones to work again. I have reset bluetooth on the Mac and that didn’t help unfortunately.

Any fix for this?

thanks

You have them paired to something else which it is connecting to?

You cannot change bluetooth versions between connections, so if there’s something else paired with, which connects to, which is a different bluetooth version, you have to turn headphones off then on before switching back to the Mac.

Are the headphones listed at another device ( eg phone).
Remember they can not be paired with two devices.
