How Noise Cancelling Headphones Can Improve Your Listening ExperienceNoise cancelling headphones use microphones to detect ambient sounds and generate an anti-noise sound that counteracts unwanted sounds.

This is referred to as destructive interfering. The crests and valleys of the waves cancel each other out, leaving only the music you are listening to. This is particularly effective for repetitive, constant sounds like the hum of an aircraft engine or Bob's constant chatter.
