ANC uses more advanced kind of tech to actively counter noise. How it works, it listens to the sound pattern outside and inside the earbud and after generates a mirror signal to cancel it out. In simple terms, it's like taking +1 (sound from your surrounding) then adding -1 (inverted noise) to make 0 which results in a reduced level of noise.
Sony WF 1000XM4 have ANC enabling you to listen at lower volume levels, good for your ears since you don't have to crank up the earbuds volume to overcome background noise.
Samsung Galaxy Buds Pro too have ANC which makes either of the devices ideal for flights and morning commutes. Each work with different noise cancellation settings, pick the setting that you prefer for commute or that suites your chill time.
