Active noise cancellation uses advanced kind of tech to actively counter noise. ANC works when, it studies the sound pattern outside and inside the earbud and then generates a mirror signal to counter it. 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.
OnePlus Buds Z2 have Active Noise Cancellation allowing you to listen at lower levels of volume, causing less ear fatigue as you don't need to crank up the device volume to outcompete background sounds.
