Active noise cancellation uses more advanced kind of tech to reduce unwanted ambient sounds. ANC works when, it studies the sound pattern of incoming noise and then generates a mirror signal to cancel it out. Simply put, it's like having +1 (sound from your surrounding) then producing -1 (counter sound by the device) to make 0 resulting in a reduced level of noise.
Apple AirPods (3rd Gen) have ANC allowing you to listen at lower volume levels, causing less ear fatigue as you don't need to crank up the device volume to overcome background sounds.
Bose QuietComfort Earbuds 2 too have Active Noise Cancellation making either of the devices ideal for flights and morning commutes. Each operate with different noise cancellation settings, pick the noise cancellation type that you prefer for commute or that enhances your chill time.
