BUT: the device is really suitable only for Apple devices. I succumbed to the misconception that one with another player simply can not use the control in the cable (which I do not need) but otherwise has a normal headset. The apparently not so. I use when running a Nokia C2-01 (Tip: brilliant MP3 player, via shortcut keys directly into the player) and the sound was very strange: Although to hear in both ears what, but distorted and as if elements are missing. Only if I have kept the "Play" button in the control element in the cable PMX685i pressed, the sound was normal (ie very good, see above). I then wrapped a band around the button so that it is held down continuously. From there, as I said, great headphones.
