I have a similar question: I just got this adapter for my xv6800:

When I plug it in to the phone with headphones, nothing happens. Music still plays out the phone's speaker. Any advice would be greatly appreciated.
I have been trying to find a good way to listen to music and watch movies, espcially while excercising. I also have the motorola s9 bluetooth headphones, but any moister (sweat) seems to ruin them (despite the fact that they are advertised as sweat resistant).
Thanks!
