I used it for 6 months ...
The sound quality is not bad but I found it hanging off.
For solidity against cot m'tais thing never happened I nerv headphone and through the valleys so pice (a Vitera people to do so) I seen how c'tait done inside, it's tiny son of insoudables so do not Bouzille btement as I did.

ngatif big point is the force of application on the ears ... is a supra-aural so it presses the flag and I never saw a headphone that supports both the ears, it is not two hours without any red ears.

The quality price ratio for me is distorted by his short life .. but I must admit it is good for a "normal" use.
I think I will not purchase this headphone if the c'tait a re ... I think plutt put cot for me to pay more beautiful that I will super gaffe
