Need help with bluetooth headset....

---

I have searched all over the net and found out that for some reason the wing isnt very good at working with bluetooth headsets. I recently bought a nice Plantronics Explorer 320 headset due to the hands free law California imposed earlier this month. I was able to set up the headset with no problem and the wing pairs fine, but when I speak the receiving end cannot hear me. I hear them perfectly fine. I have am using OTP v3.0 (will download WM7 tomorrow when ttran uploads it) and to no luck can I get anyopne to hear me. When I got home I called my house phone using the BT device so I could do some troubleshooting. I did notice if I rubbed the microphone part of the BT device I could hear that noise on the house phone but if I talk into the mic nothing. I did try this BT device on my friends Blackberry Curve and it worked fine so I know its not the BT device. Any help would be much appreciated.
