I know a few people on the spectrum using ANR headphones or earbuds in social or loud settings (party/bar/restaurant/subway) to lower the ambient noise, just as you would wear a pear of sunglasses in the sun or on a brightly-lit stage. To them, it is a welcome fix to the alternative they had before: be exhausted by the stimulation, or stay home. The tendency of "the young" to do it too is a bonus: now they don't stand out so much.

People (well, teenagers) wil.wear headphones to the dinner table if you let them.

That makes much more sense than wearing them at the party.

I guess you’re not old enough. This sounds like a feature for hearing aids.

When you’re old you can just turn them off entirely. Who’s you got talking to you at a party you want to hear anyway?

Not unless it’s a silent disco or you’re the DJ.

Folks who are hearing impaired do. And that's increasingly more of us as we age.
