To improve their comfort, buy an aftermarket headband such as Turbulent Labs. I really dislike the thin stock one.
Regardless, bend the flat metal strip inside the headband to fit the shape of your head and to get the pressure on your ears right.
To make the stock S-cushions smoother and softer, soak them overnight in lukewarm water with a little mild liquid baby soap; rinse thoroughly with cold water--press the water out gently; set them out on a towel to dry.
how much does this process on the pads improve the comfort?
