The most important thing is the sound. The just convinced me. As bassist by really rich, clear and yet powerful, but not boomy bass The rest of the spectrum pleasant and transparent. The heights are underrepresented without the use of an equalizer something I do not think is a disadvantage, since any device that transmits music through Bluetooth, also has a built-in software EQ. After treble boost the pool hiss so beautiful and natural that even a critical jazz fan is satisfied, for the classical music and the violin and flute comes beaming over. The target group of this headset will most definitely be at the more rock, jazz and pop fans. As a studio reference headphones of this device is not to be used because of the height of weakness and Basslastigkeit - but these are already located in a very different, three-digit price range. The bass are just great, rousing, groovy for the rock fan.
This annoying: Pairing with Bluetooth works without any problems with the Macbook. The Koppen still needs more than just very superficial IT skills. The included instructions are formulated in easily understandable but German, so that when a little effort and time, coupling almost every man should succeed. Raises problems rather on the software of the computer, which is not too clear and helpful even with MacOS, I fear that Windows is not better, Linux probably more complicated.
To calm: It is a jack cable here, so can also be a best-agers without IT skills simply plug it to headphones - and listening pleasure succeeds immediately and without charging.
For the Bluetooth operation, the headset via microUSB is loaded to another device with a normal USB port. Charging takes so about two hours, and you can hear more than an hour wirelessly - longer I have not tried, because I then need a break silence. The range is about 10 m by two walls throughout, outdoor certain something more.
Conclusion: A round of good, comfortable to wear, and well functioning in all respects, for everyday use headphones. The only small criticism is a slight amount of weakness that can be compensated perfectly with every equalizer - but which is counterbalanced by a truly phenomenal bass response. The price is fair, because for a headset of this quality must also pay a similar price without all the Bluetooth device.
