Query: Got this with my treo and I am sorry I did

Let me start by telling you that I am a heavy business cell phone user. Having a clear and understandable conversation is very important for me and my customers. I was very excited about bluetooth as being hands free is great when multi-tasking. This headset did allow me to hear conversations marginally well, but the person on the other end was unable to hear me. Regularly, I heard "are you on a headset, can you get off of it I can barely understand you". Apparently, I was cutting out an unacceptable amount on their end. Due to this happening on every call I was forced to stop using this headset. Overall, my experience with this product was not a good one.
