Loading music onto the JM21 from a Mac
The FiiO JM21 transfers over MTP. Android device — shows up over MTP when plugged into a Mac.
Diskoteca handles this for you: pick the albums and playlists, and it fills the device — converting formats on the fly when the player needs it. See how device sync works or read which format to put on your DAP.
Where to buy
Specs change with firmware, and we occasionally get one wrong. If something here doesn't match your JM21, email us — we read everything.
