The music player is very good.
Neat little player. The manual is available in English on the manualslib website which provides information on things like the filters. Charge up, power on, set to English, peel off the protective film from the screen, insert a MicroSD card with music on and away you go. It really, really helps if you use a utility such as FATsort after copying the files to the card to get the folders and files within sorted alphabetically. Soundwise, it's pretty good. It can drive sensitive IEMs of 12~32 Ohms, and my high impedance overheads well, but really shines when the line out is used into a valve headphone amplifier for high impedance stuff. Used as a DAC for headphones, it's again, pretty good. It's small, well specified, sounds good and is simple to use. Battery life is sufficient for a days commuting.
