Has everything I from an MP3 player in this format expected: A real USB plug, a sophisticated user interface and enough battery life. Also a meaningful key lock there. And you can play for folders (and not only by ID3 tags) Very self, I find only the function of automatic volume limiter that you have to pick up every time and apparently can not generally disable - but the volume is often enough entirely with the limit of. The supplied headphones I can not say anything, I will never use. Have regular Sennheiser headphones.
