Despite the reviews that it is difficult to use with the PC it is not, just press the button on the USB receiver when it lights up and turns yellow to indicate that it is ready for use. The device will automatically switch to low volume every time you turn it on to avoid those annoying moments when you forget to adjust the volume before turning it on. The mic has great background noise rejection, you can clap and make loud noises and you can't hear anything, my wife who is 5 feet away speaking into her mic can't hear anything either. Buy these headphones!
