Airpods pro 3 chirp/high pitch noise

Ok so after reading all these comments and booking a consultation with Apple (later cancelled - read on to see why) I am confident I have found the solution. And the answer? Diligently try ALL ear tips making sure the AirPods are “screwed” into your ear. I started with the as supplied ear tips and got the chirping. Which is actually random electronic ringing caused by the anc feedback loop overworking. I then tried small tips. No improvement which is when I booked a call to Apple. But then I thought why not try the large ones. Hey Presto problem solved for me at least with the correct size ear tips again in my case the large ones. After two days no chirping so I cancelled my Apple meeting. Now a week later and still no chirping and all is good. I’m getting 8 hours of battery life in hearing mode with a couple of hours of streaming in the mix. Of note I regularly “re-screw” the AirPods as they seem to want to work their way out of my ears. But overall a good experience. No ear discomfort after a whole day of use and absolutely no chirping. Even took a 1 hour domestic flight on a 737 in cattle class and the anc was a huge benefit. So keeping testing those ear tips until you find the right size and not necessarily the same size for both ears. Oh and that “tip” about rotating the ear tips. Rubbish. The ear tips are symmetrical. Sadly our ears aren’t. By patient and persevere. It’s worth it.
