I use it for 3 months. I use it for a very prolonged listening for several hours on all kinds of music. I appreciate his highly original aesthetic and listening comfort. The bass is powerful and not gentle on sharp ear. In addition it supports high volumes without excessive saturation, in fact it's very rock a headphone!
I am very satisfied, he could teach a headphone much more expensive than him.
I give in, but only because I have the opportunity to buy a cheap Sennheiser HD600!
For € 120, hard to find more consistent, I certainly would do the same choice.
