Headphone connectivity issues MacBook Pro

I'm having trouble using my Bose QC35, Bose SoundSport and even my AirPods with my MacBook Pro. They all connect but I cannot control tracks, turn sound up or down and the sound quality when I connect to a bluetooth speaker is truly dreadful.

This issue has only happened over the last few months and it is not just my MacBook Pro, as a work colleague is having the same issues as well.

As I say they all used to work a few months ago. But was does surprise me is the AirPods Double tap not working.

All the headphones I have mentioned above work with my iPhone XS and also my iPad Air2.

I have reset the bluetooth etc as per various other suggestions online.

Anybody else having this issue or come up with a work around??

Thanks.
