I don't know why but I can't play mp3s through my S9 BT headset. I can make calls and do everything but the damn things just won't play music for me.

Anyone who can help?

I have paired, repaired, deleted, paired. I don't know what to do...

The music still plays through the phone's speakers.

That is the combo I have and it works great, wish I could help.

I have an 8310 and an S9 headset. It works well when it gets started.... The way I do it is to start with a song playing on the media player or Flipside. Then hold down the button on the crossover. It gives a series of low-to-high tones and then a single high tone. If I stop holding the button before all of the tones are heard then the stereo audio and controls do not work and the music stays on the handheld speaker instead of switching to the headset. Messages appear on the handheld that show the phone headset, the stereo headset, and the controls are connected. Then stereo music comes out of the headset.

Hope this helps. The S9 user manual is really sketchy...
