The QC2 are about half the weight of the AirPods Max, and apparently the mesh in the AirPods Max band sags, and allows the metal bars to "dig in" to your scalp. Enough to cause irritation, but 400 or 500 grams resting on your head can't mess with an adult, developed skull.
Can anyone with a medical background confirm if this is a thing, or folks are just noticing old undulations in their skulls?
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.
One day I felt my head and decided that I was switching as soon as a competitor refreshed.
