These pads are all the rage *****. Not suitable for continuous use. The foam in the tube is pressed flat and super fast the headphones on your ears begin to exert pressure. Average I wear them 10-12 hours a week. After about 4 weeks you can feel already the slowly no longer accept the cushion its shape. It annoys me the most I have paid 2x the outrageous price until I 0815 pads for half bought even in the third month now keep their shape. In my eyes, that's what Beyer here throws on the market at the price performance ratio only one star worth. Sorry.
