Beats studio buds connection issue

I started using my new ear buds in December 2021. Everything

was working perfect for few weeks.

But since the end of January my ear buds fail to connect occasionally.

They are paired and I can see battery status popped up on my iPhone 8 when I

open the case. When I put ear buds into my ears they are not connected to

iPhone. The only solution in this case is to unpair/delete the device in my

iPhone and pair it again.It is very frustrating because it was working OK before. I noticed

that there was a firmware update in January. Could this update caused this

problem?
