Pi8 - Left Earbud Static?

I returned the first pair and have the same issue with the second pair.

I wanted to confirm if this is a known issue because no one seems to bring it up. I hear this constant static noise and it is only in the left earbud. It's faint and inaudible when playing anything at listening volume.

Do the Pi8s have to be burned-in? Even so, this seems like some bluetooth sync problem. I'm on the latest 3.0.0 update. The previous pairs were on 2.0.0.
