Samsung SCH-U740 Alias

Does anyone else have poor bluetooth reception? I'm on my second phone thinking it was the phone. I have two Motorola earpieces (H500 & H700) and unless I hold the phone up to like my shoulder, I hear crackling and static when the person I'm talking to is speaking. This weekend I went out and bought a Samsung earpiece. At first it seemed totally clean, but I'm noticing it too isn't crisp and clear like the bluetooth was with my Razr.
