Amazon gave accustomed quickly, so I could already make the first soundcheck after two days. What can I say? I'm excited. For me as a techno and rock listeners the Sennheiser are ideal. The voice of the artist is clear, the bass powerful and the centers also good. That you have to push in the plugs deep, I feel as nonsense. I have the middle essays with noise insulation and it has nothing deep stuff in order to have reasonable sound. Thus, I disagree with the previous speakers here. The scope of supply is very large, two essays sets, a bag, a cable clip and a cable reel. In the latter case a manual would be nice (I'm looking for and try yet). The operation of the remote control is also super easy. It was important for me yet, so I can give Siri commands. Also works beautifully.
In principle stands for the headphones now the endurance test, and then I can say something about life. Right now I'm just happy about the purchase and completely satisfied.
Very strong buy recommendation !!!
