If you haven't tried foam replacement tips, they make a world of difference for me. I couldn't use the airpods (non-pro) at all. I could barely use the silicon tipped pros. But when I put a foam tip on them it not only blocks out ambient sound better, they stay in place. Unfortunately the foam wears out rather quickly and I replace them around three times a year.

To be fair I'm pretty satisfied with the AirPod fit situation if I am sitting at my computer where the noise reduction is handy when the guy across the hall for me at the office is talking up a storm administering contracts and when my son is practicing guitar scales upstairs at home.

They don't fall out often and when they do I'm not worried about losing them.

Out in public is different. (1) It's a pet peeve of mine that people are wearing them and oblivious to warnings about environmental threats or sitting in a machine at the gym for 20 minutes doing nothing looking at their phone and hard to get in contact with. (2) I am doing a practice that increases sensory awareness when I "go out" and listening to music with noise canceling isn't compatible with that.

Sedna CrystalEarFit worked the best for me on older AirPods. Pure foam tips have a noticeably different sound profile.

On the newest ones, the tips have a foam core inside them.
