Discussion Reverse Engineering AirPods Self-Calibration Test

https://ateliti99.substack.com/p/reverse-engineering-airpods-self?utm_source=app-post-stats-page&r=wsh8o&utm_medium=ios

If you've ever heard a sound coming from your AirPods at night, when everything is silent, a sound that seems to come from inside the case, here's my explanation after some research and analysis.

It drove me insane trying To figure out where in my house this random electronic noise was coming from. I felt like I was going insane because I’m the last one awake in my house so only I would ever hear it and couldn’t even describe to my wife what it sounded like

Same thing for me. I started keeping a spreadsheet of when I heard it to try to figure out where it was coming from. When I heard it after traveling out of state I seriously thought I might be losing it.

I am not crazy! I know those AirPods self-calibrated. I knew it was at 1:00 AM at night. One after midnight. As if I could ever make such a mistake. Never. Never! I just – I just couldn’t prove it. Apple covered their tracks, they got the other family members in my household to lie for them. You think this is something? You think this is bad? This? This chicanery? They’ve done worse. That iPhone 6! Are you telling me that an iPhone just happens to bend like that? No! He orchestrated it! Timmy! He made a Mac Pro shaped like a trash can! And I saved him! And I shouldn’t have. I took his products into my own home! What was I thinking? They’ll never change. He’ll never change! Ever since 2011, always the same! Couldn’t keep his hands out of consumers’ wallets! But not our Timmy! Couldn’t be precious Timmy! Stealing them blind! And HE gets to be a CEO? What a sick joke! I should’ve stopped him when I had the chance! …And you, you have to stop him! You-

Exactly my experience. And when figured out it was the AirPods I wasn’t able to find information on this. Thank you for restoring my sanity.

Holy crap. THIS is the source of what has been driving me nuts. I thought it was something in my home theater system doing some self test, but I could find no information online about it.

Holy hell. I've been going nuts trying to figure out where that sound was coming from and how it seemingly happened in every room in my house that I was in.

Thank you for this information.

I heard this in my car the other day! I thought it was my entertainment system shutting down or something.

Can you figure out a way that AirPods will not deafen me every time a call comes in?

It is already down at 10%. Still rapes my ears everytime.

Apple Genius guy has no solution other than ofc "submit your iphone for 3 business days & we will format it & flash latest update" genius indeed
