8330 Curve & Motorola H15

I have an 8330 Curve on the Verizon network and recently purchased a Motorola H15 Bluetooth Headset. I can hear calls just fine, but every person I've spoken to using the headset tells me that it sounds like I have them on speaker phone and I speaking to them from across the room. Most of the calls I take on my 8330 are from customers and I need to have flawless sound clarity. I have already exchanged my first H15 at the VZW Store for this reason and I haven't seen an improvement from the new device, any suggestions?

By the way, for the first few days I had the second headset I did not have this problem.

I have the H15 with the Curve 8310 with no complaints.
Everyone I talked to couldn't tell the difference. I also use this headset on my PS3 when gaming online.

You may want to try another brand.

try the plantronics 520....oldie but goodie for me and works with my 8330 I just picked up.
