One of the common mistakes we all make when wearing headphones is that we crank up the volume when there is noise around us. This is the worst thing to do according to Electronic House in the article "The Buzz on Noise Canceling Headphones"



Real noise-cancelling headphones have a microphone on the outside of your headphones. The noise is then translated to an opposing sound wave that is then fed into your headphones along with the music. The sound waves that are provided with your music cancels out the sounds from around you.
