I have the headphones for several weeks now, bought as a replacement for Sennheiser CX 300 II. The sound is described in many reviews first class. And I think about the extensive accessories I need nothing more to say. However, I have found a point which is not optimal. Unlike the Mountain hoarse when I hear sports (running and cycling) wind noise. Running it bothers more, because I also listen to music there. When cycling less, because I only use the headphones there to just not constantly have to train your ears. But I think this is a "luxury problem" which is why I still give it 5 stars and would recommend the headphones without restriction.
