For brilliant sound for this small size everything has already been said, usually very clear 5 stars would be announced. But there is a "snag" for operation with memory card: it is issued only one channel of the two stereo channels; ie, a mono-layered Dastellung both stereo channels does not occur. The result is that some pieces of music are still reproduced badly distorted. One can all deal, in which you previously converts stereo MP3s in mono MP3s. Such software can get free on the net. However, this means an additional expense. Have the manufacturer contacted to discuss the issue. Feedback was very vague. Also is this nothing in the instruction manual and an indication in selling ads, I also did not notice => 2 points deduction. Would that part but still buy again. Bin with small luggage on the road and the sound is really awesome ....
