ANC uses advanced technology to reduce unwanted ambient sounds. ANC works when, it listens to the sound pattern outside and inside the earbud and after inverts the soundwaves to counter it. Simply put, it's like taking +1 (sound from your surrounding) then adding -1 (inverted noise) giving zero thus "diluting" the noise.
Sony WF 1000XM3 have Active Noise Cancellation allowing you to listen at lower levels of volume, causing less ear fatigue since you don't need to crank up the earbuds volume to overcome background noise.
