Cannot connect Soundcore Life Q20 to MacBook Air

I cannot connect my Soundcore life Q20 headset to my MacBook Air. It worked a few weeks ago, but then stopped connecting. I can still use it with my iphone. It is very frustrating as this is a replacement. The first one did not charge… Anker Support were good in sending replacement, though received after very long…now I have this connectivity problem. Can someone help me please: I am not a techy…but a prof now doing a lot of lecturing online

Have you tried resetting?
