You shouldn't need a medical background to know that having something press on a spot for a couple of hours will leave a depression in your skin.

You have probably fallen asleep on something patterned or folded and have it leave an impression on your skin before: This is no different.

Other places it happens: Watches that are slightly too tight or have ridden up an arm. Glasses arms pressing against your temple or behind the ear. Tight socks after a day wearing them.

It's not a medical problem. It's just general physics.

I read “soft tissue on top of” the skull to mean more than a superficial skin depression.

We have layers of connective tissue between the skin and skull [1]. Their damage usually calls for medical attention.

What he's saying though is that the original poster is vastly overstating the effect the headphone had on his head. There was no dent in his skull, just skin deformation that happens with literally every headphone.
