Tesla Motors Club

I recently bought BeatsPro wireless headphones. I was able to connect to the Tesla via bluetooth just fine and now I'm trying to figure out how to use them. My wife uses hearing aids, and I don't, and we both enjoy listening to the music Tesla includes with the monthly subscription. She, of course, has to listen on the car's speakers but my objective is to listen to the same music, simultaneously on the headphones, for better fidelity. Is this sort of thing possible? I know we can stream music from the iphone and accomplish this but I'd rather just listen to the Tesla offering(s). I can't seem to find anything on Youtube or elsewhere so your input will be much appreciated.

By the way, this question would apply to ear pods as well as Beats earphones I think.
