The noise cancellation is also great. I’ll use them if it gets noisier than my closed headphones can block.
> and finally, to my taste, they are somehow gross to look at - like hearing aids from the 1950s.
I do not care in the slightest how they look. They’re small and work well.

As someone who actually uses them, I disagree on every level.
You can get the Seinhensser Momentum 4, wireless optional, but closed over-ear and still work without battery, for less than 200. Way better sound quality than the in-ears.
The downsides you list don't apply to me personally. I don't have to "worry" about charging them; I just charge them. I have never lost them, I keep them in the same spot. I also personally think they look better than wired, but that's a fashion thing.
I think it's fine to have a different preference, but I find it odd people can't even understand the appeal of them. I don't like wired, but I can understand why people have different preferences.
