Expensive but justifiably

Sound and comfort are definitely a very individual and subjective matter. I hear mostly rock music and feel the sound as a super fit. Delivers deep, heavy riffs and crystal clear vocals in the upper height range somewhat more reserved. Overall a very voluminous, "fatter" sound, the music comes from a iphone6 ​​Plus AAC Apple Lossless format (original CD) or in exceptions with 256 kbit / s from the iTunes Store. For quality with lower I can therefore say nichhts.
The BT coupling takes after switching a maximum of one second and felt very stable. I have many hours every now and then (very rare) times a beat (second fraction) perceived, but also may be due to iphone.
The pads are very soft and also a long time very comfortable to wear. The operation (high / low, start / pause, track up / down) on the button on the right speaker works perfectly and safely. In a quiet area a radiation for the environment in the mid-volume range is clearly audible, the ICE, for example. This is the noise but again absolutely under.
All in all a good buy no regrets
