Hello, I bought these headphones because I thought if almost everyone has beats, they are already well sein.Aber I was more than disappointed! They look great and the processing is also good.But unfortunately that's it. The sound on my iPhone 6 is worse than my in ear headphones for 17 Euro.Für me sounds too washy it easy. For pop music too little power, no real pressure at Bass.Bei classical music, the highs do not come to advantage .Rockmusik was very washed out. Connected to the Denon 2312 AV receiver but they are just a little better here you realize that there is absolutely no power behind it and the louder you make the more blurred is the sound. For outsiders the headphones Alptraum.Viel are too loud, just annoying. I now have the devil AIRY for 149 euros ordered here at Amazon and which are worlds better. Even on the Bluetooth AIRY has more power than the connected cable to the AV receiver Beats.Mit to get amazed and also look at the movies one has his fun.
