Active noise cancellation uses advanced kind of tech to actively counter noise. ANC works when, it detects and analyzes the sound pattern outside and inside the earbud and after inverts the soundwaves to cancel it out. In simple terms, it's like having +1 (noise) and adding -1 (inverted noise) to make zero resulting in a reduced level of noise.
Xiaomi Redmi Buds 4 Pro have ANC enabling you to listen at lower volume levels, good for your ears as you don't have to crank up the earbuds volume to overcome background sounds.
