Active noise cancellation utilises more advanced kind of tech to reduce ambient sounds. How it works, it studies the sound pattern outside and inside the earbud and after inverts the soundwaves to counter it. Simply put, it's like taking +1 (noise) then adding -1 (counter sound by the device) to make zero which results in a reduced level of noise.
Bang & Olufsen Beoplay EX have ANC allowing you to listen at lower levels of volume, causing less ear fatigue since you don't need to crank up the device volume to overcome background sounds.
