Ok, thanks for the update. FWIW, I came across the exact same issue, only that it was with my AirPods and Mac mini. In my case the mini resides inside a cabinet that is part of my desk. I found that just by moving my head slightly, the sound would become choppy or drop out altogether. Moving my head slightly again brought the sound back. I ended up moving the Mac to a "better" location on the desk and completely eliminated the drop-outs.
Not saying that this would resolve the issue for you, but may be worth a try. However, it also reminds me of an article I read before related to this topic with PCs. I will try to find it again, and post it to see if it can help.
