I TRIED TI INSTALL A GN NETCOM WIRELESS HEADSET TO A NORSTAR PHONE. I CAN HEAR THEM QUITE WELL, BUT I SOUND LIKE I'M IN A WELL. THEY CAN HARDLY HEAR ME. ANY SUGGESTIONS ON ANY WIRELESS HEADSETS THAT WILL WORK WITH THE NORSTAR. THE REGULAR HEADSETS WITH THE CORD WORKS GREAT. THEY WANT A WIRELESS. THANKS
