Review title: Noise Reducing
Product review: This product does well at reducing minor noise. I believe it was designed with air travel in mind and it does indeed cancel out background noise such as the sound of the plane's engines or the hum of a refrigerator. It does not cancel louder noises, such as a lawnmower engine, but does mute it somewhat. The main problem I have with it is that it plays music satisfactorily when plugged into a CD player, but when plugged into a computer it developes an irritating hum.
