divers? was that supposed to say “divots?” Are there actually documented cases of someones skull deforming from wearing headphones enough? I have never heard of such a thing.

Divers wearing headphones? Regardless, I suspect that after a million years there won’t be much left of the headphones.

I expect them to dig up people with curved pinkies due to holding phones all day

Of archeologists don’t know it: “for religious reasons”.

I think headphones aren’t tight enough to leave divots, but cochlear implants might make them wonder.

I’m more concerned of what they’ll think of all the BDSM stuff they’ll find.

1. If the civilization that discovers it is more advanced than 20th century humanity, then no. They would know their purpose.
2. If it’s not as technologically advanced, the it’s possible I suppose

yes
