The AirPods Pro 2 FINALLY fix this problem. Here's the post I submitted to Reddit about it; apologies for formatting.

Now, notice [this](https://ibb.co/wsS3jq8) from the newest AirPods Pro.
By moving the vents to the top of the bud, Apple finally solved the biggest problem that plagued the original AirPods Pro. Ear wax would make its way past the grille and into the vents. When this happened, you would:
- Feel like the sound was imbalanced (it always affected my right bud before my left one, but both would ultimately suffer)
- Lose bass, and
- Experience less noise cancellation
Apple tried to mitigate this by recessing the vents slightly after they started the Service Program back in Oct 2020. [Here's](https://old.reddit.com/r/AirpodsPro/comments/izxcka/just_got_my_replacement_right_airpod_and_noticed/) a post showing the difference between the two designs. After following [this MacRumors thread](https://forums.macrumors.com/threads/airpod-pro-ear-tip-fit-test-not-working-not-the-only-one.2208392/page-38) for a few years, it was obvious that this was a design fault. I'm glad that Apple agreed!
I had my AirPods replaced **six times** over two years because of this. I ultimately landed up working with their "Executive Relations" team after "emailing Tim Cook" about it (which I never do).
I'm so glad I won't have to get them replaced anymore...at least for this!
