How it works, it detects and analyzes the sound pattern of incoming noise and after generates a mirror signal to counter it. In simple terms, it's like taking +1 (sound from your surrounding) 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 Active Noise Cancellation allowing you to listen at lower volume levels, good for your ears since you don't have to crank up the device volume to overcome background noise.
