Have you unpacked, tried and loved. The sound is really good (of course you can not expect to get a superior sound for about 20 euros), the bass is full and with a little Equilizer gimmick could be even a little bit more to tease out of them.
After 3 hours wearing time then the sobering realization: the handset press immensely to the ears. I do not have it anymore, my ears were bright red. Covered almost always, I have a relatively small head. Is probably just the headphones have not just average fit. And yes, the hinges of the earcups squeak really noisy. When wearing pure that bothers but not logically. Well would have liked to keep the above mentioned reasons, but as I was not possible. A real shame! Now I try me on headphones in the price range around 30 euros, and I hope I have more luck.
