I play a lot of games online. I wear my headphones 20 hours a day. Recently I noticed a indent on my skull, i'm not sure if it was there before but I suspect it was because I wore my headphones for long hours. Does anyone have this problem? Can gaming actual effect the shape of you skull?

Model of your headphone?

You sure the indent is on your skull? Maybe it's just on your skin/tissue on your head. Stop using your headset for a while and see if it return to normal.

If it did not go back to normal, maybe it's just the shape of your head. I doubt headphone could squeeze solid bones like that.. Unless you have like.. Baby bones.. But if you're concern.. Maybe go to a doctor and ask him if the indentation is recent or.

You might wanna take the advise from malakus.

prolong headphone usage will destroy your hearing system.

10 hours a day consider extreme headphone usage.
20 hours? i assume you are very young which your organ are still fresh. (which still functioning while having damage)

I dont think thats possible, and 20 hours is too much, doesnt it get uncomfortable after awhile? How about ur ears? And all that earwax build up

I use headphones for 10h+, the most I noticed is headphone hair

example:

and my ear squashed (hurts a bit)

i know it's too much, but you can't say no to gaming right?

yes you can.

agree.
go out social/physical activity or get a job. then u will say yes to gaming juz for an hour or two

More worried about your 20hours a day schedule.

Learn to chill a bit.

Even audio editors, producers, musicians, audio reviewers, and sound designers don't wear headphones for 20 hours a day.

Continue on like this and the indent on your skull is your least of worries in the near future.
