BT issues with 6700 and plantronics 320

[ajk511]

My plantronics 320 headset is constantly disconection, sometimes while i am on the phone. I know its not a distance issues cuz most of the time my phone is in my pocket. And when i recieve an incoming call, if i press answer on the phone instead of hitting the button on my headset, the call will only come through the phone. Is my headset just too outdated for this phone? What would you all recomend using?
