pathetic! a nightmare!

the leaflet in French stands on less than 1/4 of feuille..et very incomplete. Moreover, there is no information and I mean any information (even on the net) on the establishment headphones and after 20 minutes of testing, I still do not know ... thread up, down . ??? whatever I do it's uncomfortable and the sound is horrible. 1st use and already a false contact in one of his oreillettes..le does not pass. The buttons of the case are so hard that we must support as a patient. The sound is correct head in the water but terrible out of water, it is no more than a breath inaudible..si that when you swim front crawl is interspersed with excessive variations in volume and the sound quality and this for the same song, it's unbearable! My swimming session was traumatic and shipped. And what about the File Upload difficulties disappear after placing second in charge! The price, practicability and quality of this product fall by the scam!
