How do headphones achieve noise cancelling?
 Major headphones use active and passive type of noise
cancellation for their reliable operation.
 The active noise cancelling uses more advanced features, such as
aural overlap and destructive interference, to target and
attenuate background noise.
 These active type methods simply build a mirror sound signal that
helps to reduce the level of noise drastically. This is also majorly
used for steady and low frequency sound applications.
