I was rarely disappointed when unpacking and first test of a device. Saw the package, which does not feel to bad rating, already opened out. The first impression when I held the headphones in his hands was "ok" - see quite stylish and made a good impression.
Sitting quite comfortably, but if you then turns the music (Electronic, Trance, House), comes the disappointment. Sound can not compete with other models in the price range in my opinion, I find the reviews also clearly good and can not confirm a "quality sound".
Not quite comfortably superior to the head but from the sound her hands down my previous model: Panasonic RP-HT360E-S Hifi stereo headphones silver. For there, although less convenient, smooth 5 star.
From this product here I would say: Stay away if you value really good sound in the low-price segment!
