For the price you really can not complain. I as a layman find the sound really well. On the first day of my kink is pulling out the 3.5mm jack from the MacBook but directly slipped. Is the function of course irrelevant and I was also able to push back so that it does not really stand visually, but now the bend protection is just loose. For me, no reason for a replacement, but it's still annoying, just for as a brand name. Otherwise, the flat cable is a great thing, no more knotting. Comfortable to wear as they are, only with glasses, it can push something after some time on the ears.
