Does anyone know if you have music playing thru one of the approved soundbars from the Sonos app, say Pandora, Apple Music, etc. can you swap that music to the Sonos Ace headphones? Or is it only the device that is physically connected with the HDMI or Optical that gets swaped.

I want to use them in my workshop for when I need ear protection but want to continue to listen to the audio stream whether it be the TV or a music stream started from the Sonos App. 

I’ll buy a Beam and attach it to the TV if this works. I could play Pandora, etc. thru the TV with Roku and make it work, but if I want to have the game on the TV and listen to music this doesn’t work for me. Plus I will have a Play 3 grouped as well as a Port or Amp.

If they would allow APP Audio Swapping with the Port or an Amp, I wouldn’t need the Beam, just saying.
