Bose AE2 headband cushion discomfort

[oliverseal]

Recently purchased some Bose AE2 wireless headphones and after a couple of days of use I'm getting headaches from the headband pressing down on the peak of my skull. It starts off okay but after about an hour it feels like a lead pipe.

Maybe it's just the shape of my head?
Anyone else feeling this? Any tips on how to make this easier. Preferably not one that involves a hideous zip-over cushion.

I'm enjoying the sound output, and their aesthetic, but nearing the point of regretting my purchase due to pain. 😕
