Replying to this thread to say I am having the same issue. In disbelief finding this thread.
I have never had tinnitus (at least that I’ve noticed) until I started using AirPods Pro.
I got the Pros approx 2 months ago, using them on and off. I am very conscientious of my volume levels, using the accessibility feature on my phone to monitor dB levels. I wear high end earplugs when I go to concerts.
Roughly two weeks ago, I started using my Pros as earplugs at night for loud footfalls in the apartment above me. I found them most effective with white noise playing at a low volume (50-60dB) and ANC on.
Several days ago I noticed the ringing. Predominately as a pitch so high that it almost registered as a sensation and not so much a sound. Sounds like roughly 13.5 kHz. Left ear has a much more predominant, lower ring, probably around 5kHz.
I spent the past weekend miserable, trying to block out the sound and distract myself. I did not use headphones because I was worried about making it worse, and tried to avoid loud sounds. It seemed to improve over the course of 72 hours or so.
A couple days ago I worked out with my AirPods Pro and sure enough, later that night the ringing was back louder than ever. Almost oppressively, deafeningly loud while trying to sleep, it kept me up almost all night, only getting a couple hours of sleep. Absolutely terrible - incredibly distressing. That is when I made the connection.
I googled and that is what brought me here. I am shocked to see so many people with the same issue.
It sounds crazy but I do think it’s related to the AirPod Pros. I have a pair of Sennheiser HD1 over ear headphones that I have never had an issue with, as well as other headphones I’ve used in the past.
Never a problem until the Pros.
I am now 48 hours out from
last using the AirPod Pros and things are quiet today. The ringing is still there, but seems to be fading. It’s a good day today!
Can’t explain it, and it sounds bizarre, but the Pros are to blame IMO.
