I can not see anything positive in this product: Firstly, I must turn ever have it pressed for about 2 seconds before 2 seconds of pressing for. Then the opposition, which is now very irritated me: press 2sec to turn - works equally properly - meaning, yes, but that the press 5 seconds to couple is not possible .. therefore I get no connection.
I have decided because of the many positive customer reviews, buying me these headphones, because I thought would be pretty handy this annoying cables do not have to depend all the time on a down. But for this result, I hide the cable he prefers under t-shirt.
