Buzzing on Air Pod Pro 3s on 2 different MBPs
My Air Pod Pro3 have an occasional buzzing sound while streaming TV or movies, especially Paramount Plus. It is a buzz for a fraction of a second, but then the audio is delayed by that interval behind the video, and after a few, that becomes unwatchable. This first happened soon after I got them in late 2025, while watching on my M1 MacBook Pro. Apple Support set up a Genius Bar visit, where the "genius" told me it passed hardware testing and rather dismissively told me it must be due to my OS, and I needed to restore, so I restored, no change, then was told that using a Time Machine backup still meant remnants of old OS hanging around. This sounded like rubbish, so I didn't do a full clean install.
But a few weeks later, I bought a new MBP, M4 Pro, current OS and a clean install, no Time Machine. The Air Pods had been reset a number of times, were rest again, and the same problem occurred first time using them. Back to a different Genius Bar, same hardware test, no faults shown.
Now left with what I consider defective Air Pods and Apple not really willing to do anything. If it repeats, I am going to throw them in the bin and buy a non-Apple brand, probably Bowers and Wilkins, but before then, any ideas?
