Active noise cancellation uses advanced technology to reduce unwanted ambient sounds. How it works, it detects and analyzes the sound pattern outside and inside the earbud and then generates a mirror signal to cancel it out. Simply put, it's like having +1 (noise) and producing -1 (counter sound by the device) giving zero therefore "diluting" the noise.
Xiaomi Redmi Buds 4 Pro have ANC enabling you to listen at lower levels of volume, causing less ear fatigue as you don't have to crank up the earbuds volume to overcome background sounds.
Jabra Evolve2 Buds too have ANC making either of the earbuds ideal for flights and morning travels. Each work with different noise cancellation modes, pick the setting that suits your travel or that enhances your relaxation time.
