that’s just the shape of some people’s heads. nothing going on here

I don’t wear headsets but I have a similar shape (not sure if it’s as pronounced since I haven’t shaved it like that). The article goes onto explain that it takes near 300lbs of pressure to dent the skull and if anything it’s just soft tissue/fat being weird, which can go away through massage and giving it a break lol.

I guess if you’re wearing something as tight as a belt it might make the fat form around differently. I’m skeptical though, I just don’t know what kind of devices these guys are specifically wearing and the weight/time duration so I guess anything is possible.
