ANC utilises advanced technology to actively counter noise. How it works, it detects and analyzes the sound pattern outside and inside the earbud and generates a mirror signal to counter it. Simply put, it's like having +1 (sound from your surrounding) and adding -1 (inverted noise) giving 0 thus "diluting" the noise.
The Xiaomi Redmi Buds 4 Pro have Active Noise Cancellation enabling you to listen at lower levels of volume, causing less ear fatigue since you don't have to crank up the device volume to overcome background noise.
The Nokia Clarity Earbuds 2 Pro too have Active Noise Cancellation making both earbuds ideal for flights and morning travels. Each operate with different noise cancellation modes, pick the setting that you prefer for commute or that enhances your relaxation time.
