The earpads on my pair of k702s are thicker on one side towards the top headband. I have been trying to find a picture reference if this is the default from the factory, but google has failed me.(Or I have failed google!)
This has become more a question of curiosity since you can just take it off and put it at one of four positions yourself, but does anyone know the default one?
Thin side to the front, thick side to the rear. This is the most comfortable for me but others have put the thick side on the bottom. It depends on your head. I've tried them all and putting the thick side on the front gave me a sore upper jaw lol.
