Updated: 1 year after the purchase, return sav following problem on right earpiece, clearly as if a weld was released and as soon as one moves is death, over his or sizzling seen ... Price it is a shame !! Fortunately Amazon was nickel, refund or exchange. For cons, the international interest in France is mysterious because no dealer reprennant them => amazon clearly mitigated this problem in another way. So pay attention to the dealer from whom you place order!
