ANC utilises more advanced kind of tech to actively cancel noise. How it works, it studies the sound pattern of incoming noise and then inverts the soundwaves to cancel it out. In simple terms, it's like taking +1 (noise) and producing -1 (counter sound by the device) to make 0 resulting in a reduced level of noise.
The Xiaomi Redmi Buds 4 Pro have ANC enabling you to listen at lower levels of volume, good for your ears since you don't have to crank up the device volume to overcome background sounds.
