I strongly advise against buying-ways, see the manufacturer's website Sades, an American brand. These products are copies and are not guaranteed. Which is a shame when we receive the product with the installation CD broken as is my case. What is also a shame when we see that the original price is the same as that of the copy. In short a scam but it works and as you know you are not happy until it stops working or wherever you find yourself with the buttons on the ears.
