Bothered me the cable connection between headphones and mp3 player while exercising. With a Bluetooth connection that works well is no longer hooked to backpack buckles or fitness equipment. I can move much more freely. The player is wonderfully light and flat. With the menu control I come prima cope. The headphones fit better in my ears pierced as many models previously used, have good grip and umbrellas sufficiently well off (tested on long-haul flights). Two small drawbacks: The Knopfzelllenakku the headset has a slightly too low operating time for my taste (but any wired headphones can indeed be used as an alternative). And the controls are touch-sensitive, a real "off" button is missing.
