Active noise cancellation uses advanced technology to reduce ambient sounds. ANC works when, it listens to the sound pattern outside and inside the earbud and generates a mirror signal to cancel it out. Simply put, it's like taking +1 (noise) and adding -1 (counter sound by the device) giving 0 resulting in a reduced level of noise.
The Bowers & Wilkins PI7 have ANC allowing you to listen at lower volume levels, good for your ears since you don't have to crank up the device volume to outcompete background sounds.
