Having slept on it I now remember the issues I've had with my Bluetooth headphones

Sometimes the A2DP connection doesn't work, and then I disconnect and reconnect (not re-pair), works most of the time, but sometimes when I'm on Linux I have to restart the Bluetooth service

I dual-boot Windows and Linux so everytime I pair a new Bluetooth device I need to manually export the link key from Windows and import it into Linux, but I thankfully have not done that in many years

@quirk indeed, youre the sole person. bluetooth doesnt even work for bill gates.
