The one thing I worry about though is that they really were promising a lot with the new MLSIM training architecture, and consensus (and my own anecdotal experience) is that these newer models have not been great. They've been working on MLSIM for a whiiiiiile now and there really hasn't been any improvement, though I fully endorse why they are going that way and I understand the difficulty of the problem.
Talking, chewing gum, and even just leaning my head back is enough to make the things fall out.
I really wanted to like these things as I have terrible hearing, and the assistive hearing on these is already pretty nice, but they don't do me any good if they won't stay in my ears.
I haven't had this issue with any other earbud I've ever owned.
Do yourself a favor and try a pair out first before you buy, if you can.
EDIT: I am very open to specific recommendations on 3rd-party eartips for these things.
The regular AirPods work well ENOUGH for me that when I walk I don't need anything to keep them in, but running would be an absolute no go. And I feel like they never actually "stay put" in the ear even when walking. I always have to push them in again.
Will try these new ones, but most likely will fall back to my usual AirPods.
