    Just attached a 4ohm speaker and a 5v supply and it works like a charm. Decent volume. play/pause, forward, back and volume controls. Also resumes playback from last track timestamp.
    Works well with my sandisk extreame 32gb &64gb sd cards. minimum 5-10
    mp3 files have to be in the card for the player to be detected.
