The first negative impression came out of the box. The cable and the headphones worked qualitative advance significantly inferior to the previous (quite apart from the lousy optics ... in my opinion).
The sound of the new series is still very useful, but when my cable noise models often could be heard, which is probably due to the poor processing.
After a few months of the left earphone was however suddenly the spirit.
Conclusion:
+ Useful Sound
+ Low
- Miserable processing
- Low durability (in my case at least)
- Design
