Great headphones, great sound, unfortunately they have a design defect - the plastic element that is supposed to hold the headphones in a locked position is badly designed, because it breaks with even occasional use of the headphones in a home studio. Unfortunately, I had to send the headphones back for service, but I'm afraid that the replacement will do nothing, because this element, as I read other reviews, cracks for many people. They should replace it with a more durable material....
