Media :: Dual Pairing Bluetooth HT820 Headset For Media And Phone?

Almost a year ago I purchased the HT820 Motorolla headset so I could pair a bluetooth phone and mp3 player to the same headset. It worked fantastic. Now that I finally have my hands on the Google phone, I was hoping to dual pair the headset to the phone for both media and the phone.

I don't know if I am doing something wrong during the pairing procedure, but it will not play media through the headset, except in the second before dialing a contact or just after I hang up. Whatever music is playing, comes out of the speakers, but like I said if a call comes in, I hear the music through the headset until I answer, and then it pauses like it should, then plays again after I hang up but it switches back to the external speaker almost immediately.

It works fine for the phone, and in the Bluetooth list of devices, it shows as connected.
