Lightweight, easy to use, cheap and a remarkable listening. The supplied headphones are quite acceptable. A remarkable autonomy. The internal battery once charged seems duration of the week if it is not in use. A default, however, it seems slow when adding files. There is a phase after adding one or more files in which a progress bar is displayed and this can put a little time. To overcome this defect, I passed under RockBox, a kind of alternative to the original bones. Since this concerns disappeared, I won a few more features (equalizer, graphic themes, various plugin).
