Hi all, Just picked up a Plantronics 925 BT headset to use with my iPhone 3G... I'm having problems with "echo"... that is, I can hear my own voice in the earpiece as I'm speaking. I have a few other BT headsets, so I know this isn't normal... it's kind of irritating actually. Does anyone else have this problem, or know of a way that I can "fix" the issue? Other than that, the sound quality and reception is great... just hope there's something I can adjust to fix this echo... thanks.
