I also didn’t understand why wired headphones don’t work besides profit protection. Suppose that having to hold the phone mics forward is clumsy but would like to have the option.
I can understand that position, but in practice I don't think you'd like the quality.
One of the big advantages of hearing aides is that they have multiple microphones that have known alignment with your head position. With all 4 mics separated in space, they do a good job of isolating audio coming from in front of you vs from around you.
Plus people can lose hearing in different bands: they might hear bass fine but people with high-pitched voices may not register. Just turning up the volume won’t address that.
The FDA regulations allowing for OTC hearing aids didn't go into effect until a little under two years ago, so regardless of the technical feasibility, the market viability of what you're asking for is a recent thing. (Though since using wired headphones with smartphones has been in decline for well over two years, the market viability is still questionable at best.)
"Musk took to the social media platform to announce that X would relocate to Austin, Texas, due to his fury over a California transgender protection law." What happened with going to Texas?
