It’s tough to tell, but the issue looks fairly prevalent. Anecdotally most others who posted on Reddit and MacRumors have gotten replacements to have the same issue. Very few on such posts say they have no problems, however not everyone can hear high pitched noises so there’s that. For the record, I returned mine because I have AirPods Pro already and they just work, on top of the noise cancelling. I believe Apple engineering likely knows about this and is probably starting work on a software update. Previous versions of AirPods have had similar problems, so I think it’s just a waiting game, so decide on whether you want to wait or not. I did think AirPods 3 had the best sound profile yet though!
