Theory:

Noise-canceling headphones reduce unwanted ambient noise with active noise reduction. The theory behind this is that, picking up ambient sound with the microphone and play it on stage, you can actively cancel or "null" background noise. Essentially, this is a microphone at the ear and the electronic circuits usedgenerates an "antinoise" sound wave 180° out of phase from the sound wave arriving at the microphone. This results in destructive interference, which cancels out the noise within the enclosed volume of the headphone.

The passive or the low-tech, way to cancel noise is simply to wear closed-back, circumaural -around the ear headphones or very snug ear buds. These shield your ears by sealing them off from the outside world.
Active noise Dismissal, on the other hand, is much more complicated. First, each portable microphones, to detect ambient noise before it reaches your ears. Then the noise cancellation circuitry is housed in an external module, essentially returns captured signal, the sound of the waves upside down. Therefore, only a short time, the system adds noise cancellation, the opposite tonal noise outside, what you are listening and make the most pollutionand leaving you with just your music.

There are a few disadvantages of noise-canceling headphones such as:

o These headphones consume power and hence batteries are to be used which must be occasionally replaced.

o They may introduce additional noise, usually in the form of high-frequency hiss.

o Size is an issue here as they are generally more bulky than traditional headphones.

The noise cancellation headphones are a boon for frequent fliers. You can now escape the continual background noise of the engines and the plane. You would be able to enjoy your plane ride peacfully. When you use them, you can enjoy movie soundtracks or music because there is less background noise to fight against.
