Query: Superb product - Plantronics Voyager BT Headset

I already had 3 BT headsets and saw the Plantronics in an airport. Couldn't justify spending money on another one. Got home and had another complaint about the sound quality of a call with a business associate and caved as Amazon had it for a really good price. I paired the Voyager and was immediately impressed by the instant improvement in the quality of the calls. Sound is clear, range is good and it is so comfortable. This is unquestionably the best BT headset I have ever used. I give it 2 thumbs up!!!
