Sound: by and large, the sound is passable. Both the height and the bass does have to make a little compromise.
Processing: The connector itself acts meticulously crafted, no gap, no chromatic aberration or the like. The cable acts, to put it mildly low. It is from the feeling by far the thinnest cable that I had so far in my headphones. Whether this is for the lifetime of disadvantage to be seen. Furthermore, the cable used to connect "earpieces" of different lengths (left cable about 1 cm longer) are. Whether I caught a Monday product here, or which is generally the case, I can not say. Furthermore, the Kunstoffaufsätze are for my taste come into the ear to hard (inelastic).
Addendum:
A new ear Support - - Based on my review, I was the CSL sent headphones. In this, the cable lengths of both sides are the same now, even is quality of the cable now works better.
At this point I would like to express kudos to these customer service and the uncomplicated complaint.
