Did the boomboxes-next-to-heads and the walkmans of the '80s and discmans of the '90s not count? I think a lot of game boy users also used headhpones.
I actually didn't use them that much at all, but I still have trouble hearing with background noise. Noise-cancelling headphones have actually been an amazing thing in my life because (a) it helps overstimulation and anxiety and (b) it actually helps me hear someone talking to me because it filters out the other stuff. I suspect my problems are a combination of mostly-neurological (ADHD and probably (though not officially) ASD) and maybe impacted by loud concerts and general aging-related stuff. I can still hear really high-pitched sounds and the like whereas many of my peers around my age and younger can't as well, but it's all mud to me when there's a lot of sound.
