The sound in the bass range is simply madness. Whether Techno, HipHop / Rap or other music with Beat, I have never experienced such in this type headphone precise and crisp bass: -o! The first song (Atzen - Disco Pogo) with the things I've been amazed how this is possible without end to something rausholen in design. In addition, vocals and other heights in this kind of music are super tuned!
But be careful!
As soon as you want to hear, for example, at night in bed quieter songs (more singing, no bass or audio books, etc.), the sound is too bassy. There has anyone ever described, the depths come too and swallowed something the sound of the voice. It all sounds a bit "dull" to. If I had the bass can not runtersetzen on the EQ, I would have put away the iPod. (Old Nativ you can also set "more ups".)
The processing of the headphones is good. They fit perfectly to the ear canal (3 diff. Papers are). However, do not touch the cord, especially the upper two thinner, transferred directly into the ear. When "normal" listening to music you do not mind!
Conclusion:
For heavy bass music headphones are really suitable. For other music should NEN EQ have, otherwise these headphones are not really the right.
