I went to an Apple store to see if I could get them replaced since I knew there was a recall on one version. They refused since mine was the version that came out after the recalled version.
That soured me on AirPods. Luckily it was a work-issued pair, so they were free.
I have one pair where the left bud doesn’t connect until I put it back in and take it out of the case a few times.
One where one bud doesn’t charge properly.
And one with declining noise cancellation.
They are great when they work properly, but I do think quality is slightly lacking for a relatively expensive product.

Beyond that, the whole culture is to repair things because there isn't an official Apple store. They can also import parts from China and elsewhere.
Here is pricing to get parts from Singapore... most expensive repair is $100...
I spent a few days wondering if I had just lost hearing in that ear, but no.
After that terrible experience i couldn’t justify the expense of buying an other apple airpod.
The Pros, on the other hand, in spite of me generally being quite careful with them (in contrast to the basic AirPods) had their noise canceling crap out at about the 2 year mark, and currently are slightly louder in one ear than the other (but the microphone still works, so they remain in service).
So, overall, I think I’ve had a similar experience to you with the Pros, but have been quite impressed with the non-Pro model.
Anecdotally, I think I noticed a difference, but I also chalked it up to prematurely-degrading hardware...
Use some blue tack to gently clean out the microphone grate(s) periodically. As it becomes obstructed noise cancellation suffers.
The noise cancellation is the weak part. The microphone or related hardware breaks and then you get all kinds of plops and squeals unless you turn noise cancellation off. Somehow they tend to do that about 3 to 6 months after warranty...
I was surprised at the quality, and they've lasted a couple years already at almost daily use.
The nice part is, if I lose them, no big deal. I bought a 2nd pair as a backup.
AirPods are disappointing, but convenient. I guess that's why we buy them.
