Hi all, I've had my BB Bold for almost a week now and I love it! However, the sound quality through my bluetooth headset is awful. Can it be fixed?

I've been using this exact same Plantronics headset with my old phone (Sony-Ericsson W600i) and the sound quality has been phenomenal. With the BB, though, I hear a hissing noise almost all of the time during calls, and the other person is difficult to understand at times (it's like it makes everything sound fuzzy).

The range is quite a bit less with the BB compared to my old phone, but I can live with that. Is there anything I can do about the sound? I love this headset but it's making calls sound really bad. Thanks!
