I used to use a HTC-6700 / Sprint, and people told me the same thing. This was a result of the Phone's bluetooth stack and not the X5 itself.

I bought a Motorola H815 and added it to my Verizon account and it worked fine, so I was using two phones in the car. 6700 for business and 815 for bluetooth connection while in the car.

My company recently ditched the 6700 and we have iphone 3g's. Bluetooth stack on these are great and people say I am loud and clear. The stack on the phone has a LOT to do with it as well. So if you dont get the results you want, try a buddies phone and I bet the problem goes away.
