Last week I used my AirPods Pro to listen to some music while on a flight, and during takeoff, my right ear started hurting that I had to take out the AirPod completely. I’ve never had problems with cabin pressure changes, and have used various in-ear and over-ear headphones, with and without noise cancellation during flights. The next day after that flight, I used my AirPods Pro again for a couple of hours, in Transparency mode while walking around town, but my hearing on my right side is now slightly muffled and I’m getting ringing in my right ear. I don’t listen to my music loud, and according to my Apple Health headphone audio levels, it’s been an average of 50-60 dB, well within the safe range for hearing. It’s been going for several days and I’ve got an appointment to see a doctor about it.
Since that incident, I’ve done a bit of testing and experimentation, and discovered that if I have both AirPods in my ears, turn on Noise Cancellation but with no audio playing, and push them both as far as they go, I hear a very low frequency rumble that gradually increases in volume on the right side. I stopped after a few seconds as I do not want to aggravate the problem or damage my hearing any further. This also happens with Transparency mode, but to a lesser degree, but not when NC is turned off completely.
I had previously encountered a sensation of fatigue or ‘pressure’ after using my AirPods Pro, particularly after using them for Zoom/Hangouts meetings. At the time I had just assumed it was either earwax built-up, or the low bitrate audio quality of online meeting software. That sensation would go away after a few hours, but this time, it’s been several days and I’m getting concerned.
I suspect my AirPods Pro are faulty, and the Noise Cancellation microphones or internal circuitry is boosting the noise cancelling frequencies to possibly dangerous levels, while regular audio remains at a safe volume. When I did the same test with my partner’s AirPods Pro, I did not get the same ramp up of the low frequency rumble. I’ve asked him to compare the two and he too can hear the difference between my pair and his own, so it’s not just me.
I just hope this tinnitus is temporary and I haven’t damaged my hearing permanently.
