Unfortunately far below expectations

I wanted to use the radio on the train in the Rhine-Main metropolitan area, to better provitieren from DAB + sound stage. Unfortunately this is not possible. There are so many dropouts, despite relatively good reception that listening is not fun: The reception power is too weak, in spite of sufficient signal strength. In addition, this is the digital to analog converter apparently of poor quality, since, for example piano passages rattle and voices are sometimes easily consumed. I do not know of other DAB +. I used a Sennheiser headphones, not the supplied. MP3 is quite nice, which was also a reason of purchase. This works fairly well. However, all folders must lie with songs in the root directory and the player does not notice the last played piece so that always has to be started from scratch. Since it was appointed before Christmas, unfortunately, the return period was exceeded. Oh yes, the battery lasts no 7 Hours, the level indicator is inaccurate. Maybe I have a "mon copy" caught.
