What is Active Noise Cancelling?
Active is like you washing your car to make it clean. It takes effort to cancel noise (electricity and electronics). Passive would be allowing the rain to rinse your car (zero effort). In this case a headphone that seals the ear from the noise source like passive ear protection or ear muffs. The TS-BH05 Active Noise Cancelling wireless headphone uses both. A large padded cup to create a chamber and active electronics to provide additional frequencies that make it so you can not perceive the noise frequencies.
