A way for two people to listen to the same iPhone while jogging?

My wife and I are starting to jog together, and would like to listen to the same music while we do so. It would be great if we could both hear the coaching from our C25K app, but I'm not sure if that's possible.

I know that 2 bluetooth headphones are out of the question, and my research indicates that we cannot run a wired headphone and a bluetooth headphone at the same time. Wired headphones and a splitter are obviously out, since we will be jogging.

I was looking at the Eavesdrop app, but it says it only plays DRM-free music, which seems to indicate that anything I've actually purchased will be unavailable to stream.

So . . .

Is there a solution to either have a wireless/wired headphone combo running simultaneously, or a way to stream the ENTIRE audio output via bluetooth to a second iPhone?

Thanks in advance!
