I'll thinking about going to these from the AirPod Pros. The APPs simply don't stay sealed in my ears even with the slightest movements. I've got these after-market silicone "wings" that help a lot, but I have to remove them (and not lose them) to use the charger case. Grrrr.
I have both, and for me APPs are excellent. These BFPs are just a bit more functional. Maybe they sound x% better but not by much. The physical buttons and rock solid fit is worth it for me (I do a lot of cycling and HIIT workouts).
Honestly though, it’s kinda nice not having the obvious Apple stems hanging out your ears sometimes. Some days I think that’s cool, some days I’m not so keen.
