? Go figure?Seeing as I brought it in from the USA to South Africa, I just dont have the inclination or time to even attempt to return the product. This cord destroyed my headphone input on my I Mac computer. When my mouse first came i was happy and because i wanted a new mouse I buy this and at first for its very good then fast foward a month and my wire is torn just buy me moving my mouse and the wire is so close to the mouse whenever you pick it up the wire gets stuck underneath it DONT BUY THIS ITS A WASTE GO FIND SOMETHING BECAUSE ITS THE PACKAGING ISNT GOOD ENOUGH FOR THE WIRE you can see the picture that i posted it tore in a month and now it disconnect and also the SOFTWARE is very hard to get Anyway - they do work, though. I ordered the gray size 8. My original charger lasted less than a year with minimal use. bought this to use in a camper, in large part because I can use 12v DC to charge and power it. This case is very rugged and keeps them protected from falls, dust, screws in my pocket, etc. Identiques à la photo. In comparison, I have about 5 different pair of dual driver in ears.
