So I can not understand the many positive Rezesionen. Perhaps the player is to use if you just want to listen to music with it, or has entered into a subscription at Audible. Only these audio books can be separate from the listening to music. Normal mp3 audio books are always in the music folder and if one now uses the Shuffle function there, one just has always wanted a chapter of an audiobook. Total nonsense. Apparently Audible has a contract with Phillips ... I think it should be given of sellers that you can only hear audio books from Audible decent. I also checked with the support, if only I am not capable of audiobooks right to pack to the player - but no, it's not my "stupidity". The support has confirmed to me that it is not possible to separate audio books in mp3 format from the normal music. But only through the folder structure you can select an audio book, then works not bookmark feature! So I hear in between a song I have heard only then looking for the right audio book in the folder and then the place where I was ... not the point. For me, this player is not available and I got him sent back naturally. By no means a buy recommendation. I use more my Sansa Clip +.
