Sound trough Bluetooth and wired headset

Hi pll!
I have a flat s7 with no root and I'm not find a way to play music trough my Bluetooth and wired headsets.
Probably the s7 allows to pair two Bluetooth devices but is quite expensive for me buy another.....
It's possible by to achieve want I want with a App? If so, show me how!
Thanks in advance
