Transfer to external mp3

[craig.d.evans.5]

I was wondering if it is possible to transfer music from my galaxy S4 to an external mp3 player through a usb cable..
Any idea how to achieve this would be great.

Thanks

Welcome to Android Central! If that's possible, it would probably require an OTG cable, which would allow the phone to access the MP3 player as an external USB drive.
