Simultaneous audio to headphone jack and bluetooth I would like to output audio both to the headphone jack and to bluetooth headphones simultaneously.  The purpose is for two people to listen at the same time (and we don't have a headphone splitter at hand).

Is this possible on Android phones?

The phone in question is a Samsung S5 mini with Lollipop.
Unfortunately, this can't be done.

Android can only output media to one of them at a time. 

When you plug in a new device, the last one used will be overridden.
