okar fair enough that was a cracked set here is another video of the apparent buzz in the new 2010 model c8600 and this one is not broken, fresh out of the box, be sure to crank up ur speakers volume, u can hear the buzz, especially when he mutes and then unmutes the set, and don't blame it on the camera mic when the guy gets up at the end, every slight sound made is captured by the camera mic, so that hissing buzzing sound is definately the buzzer. Hell if it gets picked up on the camera wonder what it will be in person.
