bluetooth sound quality problem

[amol_pat]

I am very new to windows mobile based phones (this is my first one). I used GoodThings2life cleanup. It is great, TF is extremely sensitive now (my iphone crazy freinds are reconsidering their love!). I had a question regarding the bluetooth though. When I got the phone out of the box, the volume was too low; however with my plantronics 925, it sounded great. I installed the clean up with loud audiopara first. But it was too loud for me. Then I installed only the light audiopara cab from this post. The phone volume and sound quality is perfect. However, when I use the plantronics with it, people on the other end complain that my voice quality is really poor (sounds like an old loudspeaker ). I have been using the same bluetooth with my previous phone and it has been great. Any suggestions are greatly appreciated..

thanks,
