I purchased this headset with my new Verizon phone. It was so neat; I wanted to use it all the time. Yet, everytime I used it, the person on the other line complained their voice was echoing (both land and wireless). I thought that the initial complaints I was receiving were just conincidence and that I probably just needed to sync the devices again. I tried to fix it, but eventually out of desparation, I purchased another Motorola (see review ECHO Can U hear me now?) headset with the same results. I would not purchase this headset for use with Verizon LG 9800.
