zero down the line 1

I agree with the comment Nounounette - even more critical. I made these headphones offer (and I have a wired AKG I'm very happy), and I do not have the invoice otherwise it would be left to the sender (and more and I dare not say to the person who offered me the extent of the disaster given the price). The sound is simply unconscionable, it saturates from lower volumes even in greatly reducing the bass. A helmet for children 5 can not do worse. So I think I came across a faulty model, except that I am apparently not the only one.
The sound of the report is already final, but on top of that, it is not beautiful, not comfortable, bulky, and Bluetooth connectivity is missed: the threshold device of this type that I have to use every réappairer (well ... for what little I used it ...) and again at the last test he well took five attempts before he deigns to connect. The buttons are not intuitive and are uncomfortable (hard and noisy) with use.
At least I do not have time to be disappointed with independence.
