This is how I use my portable bluetooth speaker. I use it to play mp3 music files which is read off the micro SD memory card that is plugged into the bluetooth speaker. You can find bluetooth speakers with micro SD card capability at Amazon (affiliate link): amzn.to/2ioTpSh

This Lexar 64GB Micro SD Card on Amazon (affiliate link) is all you need: amzn.to/3BVsF2R

If you like this feature, be sure to look for a bluetooth speaker that can accept miscro SD cards.
