I knew that listening to music with the device is pointless because everything is only in alphabetical order. Just normal audiobooks. Due to the battery life, which is quite good, I still bought the device: For my Audible books. But what annoys, is, on the one hand that you can not use the function section. One can only jump to the next or previous audio book, but not in the audio book, this one must coils. But good. Even more annoying, that the response time is sometimes very long. Pressing "Play / Pause" or "Stop" it may well take time for 20 seconds, until the thing responds. Sometimes you go on within 3-4 seconds. Then again, it takes significantly longer. So I have often pressed for a second time, because I thought I might have not pressed firmly enough. Because the thing only responds when you firmly and long suppressed enough, the thought may come one before. But then it takes listening right back up because they both commands are executed. I find that extremely annoying. But unfortunately there for Audible books at the moment just barely viable alternatives ...
