The hearing aid feature, to me, is a little overblown. It feels to me like the biggest positive impact it will have is, with some luck, forcing down the price of typical hearing aids and opening up the conversation on more competition. It might also be good in a pinch, and good for lower income customers(?), but I think at the end of the day there's a reason why hearing aids are generally pretty slim, skin colored, and innocuous. There's no reason why I have to take my Airpods out when I order Chipotle, I can hear everyone perfectly fine with them in, but I do because there will always be social stigma talking with someone who has earplugs in.
There was an "event" on Threads a while back where a wedding photographer asked "the world's" opinion about asking attendees to take their Apple Watches off. Some people say "oh hell yeah, those are gaudy, I don't want any of my wedding party even wearing one at any point in the event", meanwhile one person responded "The Apple Watch is literally a medical device for me, I need to wear it as often as possible, I can't take it off". Idk; feels like a related concept. Sometimes the social stigma doesn't matter, these devices drive some people insane with anxiety about their health, Apple's marketing plays up the anxiety because it sells hardware every year... at some point, someone will say "I can't take the Airpods out, they're my hearing aids, as diagnosed by iOS 18.1", and maybe this is just me being an old man yelling at clouds, but... that's cringe, go see a doctor.
The other angle I don't hear talked about enough: The Air Pods Pros don't have the battery life to really fill the same role as hearing aids.
