I have transferred songs to a memory card but I cannot play some of the songs.




Some of our products have a built-in music player with a card reader. You can transfer your music to a memory card and play them on the Betron speaker. After you inserted the memory card in the speaker, please change the mode to the music player.


The built-in music player can only access to the root folder of the memory card. Any songs in subfolders cannot be played. Please also note that, if there are special characters in the song name, the player may not be able to read the music file.
