How to use Bluetooth headphones while linked to PC with SideSync over USB?

[AC Question]

Samsung Note 5
SideSync connected to Window8 PC by USB cable
Bluetooth headphone connected to Note5

When connected to PC, audio playing on my phone is heard through my PC speakers. How can I listen on my Bluetooth headphones connected to my phone?

Bump. I'd like to know the same thing. It's annoying that the audio link breaks.

I know this is a while ago but I was working with this today.
I am able to push the audio back to my bluetooth headset by disconnecting and reconnecting my headset after connecting with SideSync.
Specifically, after I pull the phone screen up on my computer I turn off the bluetooth on the phone, wait a few seconds and turn it back on.
When the headset reconnects to the phone the phone audio will come through the headset.
