I waited a few days before making a comment to the test so as not to make the same mistake with the Sennheiser brand precedent among others. Two days after a comment he left lollipop, his big weakness the son connection / headphones if you hang ever so slightly an office corner with the sound volume wheel module (this happened even paying attention) completed more sound from one side or the other, so trash management. With this one of Hercules brand is seen very well that he does not have this weakness is one of the criteria of my choice with the fact that I was pregnant of this brand were largely satisfactory. A little rigid and makes me ears hurt because of glasses, but in his defense I long door when I play. Good sound, I am not a specialist and mainly supply the speakers with a single thread of good section instead of two purposes for some brands. To conclude: I am very happy and something tells me it will last, I was mare disposable headsets.
Rectification.
Finally he broke in to a place I did not expect so disappointed and return to square one with another model that jévaluerais later without rush.
