I have now tested the headphones for several days across all musical genres. The sound is pleasant and it gives the music like this as it should be. That means to me that he is neutral on its own initiative and not all zudröhnt with basses. If I want to Bass, I want to also be able to adjust itself. My music gets partially quite different characteristics. When Norah Jones, for example, all instruments are clearly differentiated and result in a harmonious overall picture in mind.
One more comment to processing:
Some people think that the headphones feels cheap, because it is so easy. I can not confirm absolutely. It is actually easy but everything is screwed, so I think that one can also fix it well if something is off.
