Opposite 3 from me tested -pseudo- MP3 Player can with this player! No! any conversion programs every MP3 files are used. Via USB through Explorer simply create folders and reinkopieren, as it must be.
(Went with Sony and Panasonic not !.)
Benefits:
Small, but big enough for very neat, quick operation. Very good earplugs.
Sony Software is fine to select and sort of music.
Disadvantages:
not found.
The device is to look very handy and beautiful. The sound is 100% super and can be changed with various adjustments in the sound settings. The battery life is real with about 14 hours (in the main unit without flashing but LEDs can be switched off) well.
