i put small aligator clip on the back mp3 with hot glue and attach to my huawei band 10 nylon strap.i also can control the music with bluetooth earphone

i can control music from my huawei band with phone while using bluetooth earphone

its very cheap and has good warm sound

first the earphone must be connected to the volume controller before plug in

1.high impedance mode: set the volume to 75% before plug in

2.normal mode : set the volume to 100% before plug in

3.external mode : set the volume to 0% before plug in

high impedance have the fullest volume ,external mode more volume than normal mode and normal is basic volume..you can also use this this method with any earphone,headphone that got volume controller built in
