Review title: This is a fair warning: do not buy this set!
Product review: Instead of canceling noise these headphones add a hissing white noise. It's even hard to say if the cancellation works at all. Something changes with the sound when you flick the switch, but the level of outside noise seems to remain the same. The battery box "strategically" placed on the inside of the headband will continually remind your sore skull that it is there.Whoever worked for Sony on designing this set should be made immediately available for employment.
