The headphones sound very good for my taste. Not so bassy like the models from Bose. Processing looks very high quality and the folding mechanism is fine. What I think is very good, that you can change the cable itself. The supplied cables make a very instabielen impression but so far everything ok. By contrast, the supplied transport box acts pretty cheap but they work. One point deduction for the high price differences to the colors. Why does a model in black and 40 more because there is no reason for non-rip-off. The headset is a strong buy recommendation
