Bought May 19, 2014 here, he just fell down. After using could not be more normal, I do not mean only one headset. At that price it's very, very disappointing ... I just make contact by email on the Amazon website --as I've also because no way to write about this order and legal guarantee a year! So I had to take "another excuse" to get contact Amazon for the legal guarantee of this article. I expect an answer, and according to the known-answer I will modify my review accordingly. The next call from Amazon that tells me to support the legal guarantee. I was offered an exchange, I accept of course. On Thursday morning, helmet nine received in exchange for the defective helmet. So I returned the old helmet. I hope it will not experience the same disappointment! Anyway, kudos to Amazon so honored to have the legal guarantee. So I added 1 star for Amazon, but no more for the headphones while waiting to see the evolution of it.
