Hearing enhancement for everyone is easy with current tech. But people won't do it because it looks like you're disabled. But once enough people do it, it'll no longer look that way and be cool like sunglasses. But they are not. So we don't. Strange world.
Disagree, my family has a history of bad hearing, and both my grandfather and my father wear them in both ears (I'm waiting for the day I need them). A few years ago I thought my father stopped wearing them but it turns out they make them so small these days, they are only visible if you're looking for it. My grandfather got the newer model which comes with a small remote he keeps in his pocket. He turns off all sound when his wife is talking too much :)
