I,M A TRUCK DRIVER AND THIS HEADSET IS PERFECT FOR USE IN TRUCKS, MY FRIENDS TURNED ME ON TO THIS MODEL. I USED OTHERS THAT SAID THEY WERE NOISE CANCELLING AND THEY DID A NICE JOB IN MY CAR BUT SOON AS I USED THEM IN MY TRUCK NO ONE COULD UNDERSTAND ME. THE BLUE PARROT HAS A NICE QUIET SOUND TO IT, EVERYONE SAYS I SOUND GOOD ALSO WITH THE THE CUP EARPIECE I HAVE TO TURN THE VOLUME DOWN OR IT BLOWS ME OUT SO YOU HEAR VERY WELL WITH IT. THE ONLY THING I HAVE EVER HEARD CLOSE TO THIS WAS THE PLANTRONICS 510 BUT THE EARPIECE WAS NOT EVEN CLOSE TO THIS
