The other day I was driving down the road listening to my iphone through my aux input in my car and I had my Jawbone connected to my phone also. I received a call from my wife so I unplugged my phone from my aux input and answered the call. So while on the phone with my wife I decided to see what would happen if I played my ipod while I was in a call. Well sure enough I could hear it great (music that is). So I asked my wife if she could hear the song and she said no. So I guess the point of my post is to ask if anyone knows how to use you bluetooth as headphones while not in a call. I tried ending the call and hoped that the ipod would still play but it didn't. It went on to play through my speakers.
