I purchased this for the office. I maybe have a 100' range before the headset cuts out. Most salesmen in my office use Jabra headsets and they easily get 3 times the range I get. Buy the Jabra!!10/11/12 A couple of coworkers purchased new models from Plantronics and they also get good range. So I'm still in warranty and called customer support again. They said I should have the same range so they sent me a new unit. STILL TERRIBLE! I THINK THIS ONE IS WORSE! CALLED AGAIN AND EXPRESSED HOW DISAPPOINTED I WAS IN THIS MODEL AND EVEN OFFERED TO PAY THE DIFFERENCE TO UPGRADE. THEY SAID SORRY CAN'T HELP YOU, BUT WE'LL SEND YOU ANOTHER PIECE OF CRAP IF YOU WANT! I TOLD HIM I WOULD PROBABLY HAVE TO TAKE MY BUSINESS ELSEWHERE AND HE DIDN'T SEEM TO MIND. I'M A PART OWNER IN A SUCCESSFUL COMPANY WITH 30+ OFFICE EMPLOYEES. NOT A GOOD EFFORT BY CUSTOMER SERVICE!!!
