This affects me as well. I'm a heavy user of the original 1st gen Airpods. I am a die-hard Airpod lover. They've changed my life. I listen to 20 books on audible each year. I'm significantly more productive being able to speak with people while accomplishing other tasks with ease. I've purchased every single generation of Airpod at this point. Here's my story:
I had been using the original Airpods for years with seemingly no ill effects of hearing or tennitus. Extremely happy user. Would tell everyone to get them. When I saw the Airpod Pros come out, it was a no-brainer purchase for me.
So after wearing the Airpod Pros for 2 weeks, I noticed a constant high ring in my ears. I stopped using them and the high ringing sound greatly diminished. I used my original Airpod and the ringing did not return to the high levels.
As soon as the Airpod 3s came out, I got them. After 1 week the high ringing returned. I stopped using them and the ringing diminished (still there but only noticeable once in a while).
I then purchased Airpod 2s! Thinking maybe it's the shape of the Airpod 3s. (since I knew it wasn't the noise-canceling since the Airpod 3s don't have noise-canceling). After using the Airpod 2s for a week, the high ringing returned!
At this moment, I'm discontinuing the use of the Airpod 2s and returning those. We'll see if the ringing subsides again. I've already purchased original Airpod 1s on eBay lol. We'll see what happens.
Definitely really sad that I may not be able to use Airpods anymore. For me, there's a very strong correlation between using anything 2nd generation and up with tinnitus. Assuming that the original AirPods are the only ones that do not cause tinnitus for me, I'll be out of options in a couple of years. Apple, please figure this out!
