Because I bought these headphones for my BlackBerry. It is stated on the product that is suitable for ALL types of phone and the package itself that is intended to run on a BlackBerry. But it works, yes, listen and pause. But to move to the next or previous music track, not at all! So if you want to pay this price for doing what any ordinary listener, perfect, if not, keep looking. I am very disappointed and I regret having bought!
