LG V VX-9800

I just recently got the Motorola HT820 headset for my phone and seem to be havin problems with it, the main thing being that when other people talk to me it echos on their end but I hear them perfectly fine. Another thing is that where I work I am getting a lot of static and cracking, i thought it was the headset so I exchanged it out for another one, same problems. I'm thinking about getting another one.

Guess what I am asking have others had this same problem and what BT headsets have they had success or like. Thanks
