I am very disappointed by this product. By paying 60 headphones, I was expecting a certain quality of manufacture.
It is not. Only a month after the purchase, the right earphone (and therefore the one with the microphone) HS is more sound, more micro, more controls !!!
Obviously the date 30 days has been exceeded and more possible to support Amazon ...
Really weak product, I said that I was putting it in its box every day when I did not use ... impossible to be more cautious (except for not using).
