The quality and design of the headphones are very good. The cable does not verzwirlt. Taken out of the bag, it can immediately go. However, the cable is heavy and a bit annoying in sports. The sound quality of the headphones is especially high in the area very well. Unfortunately you have to make some area once Riche in Central and bass. My Sennheiser, who are even a little cheaper, offer as a much better sound and are especially a lot louder. Bad I find the included clip to attach the cable to the clothes. The cables are constantly flying out of the holder. Have the headphones therefore given away to someone who is not so audio affine and headphones class found. All in all, the headset ok. But in my opinion they do not justify the price.
