ANC makes use of more advanced kind of tech to reduce unwanted ambient sounds. How it works, it studies the sound pattern outside and inside the earbud and then inverts the soundwaves to counter it. In simple terms, it's like having +1 (sound from your surrounding) then producing -1 (counter sound by the device) giving zero resulting in a reduced level of noise.
Xiaomi Redmi Buds 4 Pro have Active Noise Cancellation allowing you to listen at lower volume levels, causing less ear fatigue since you don't have to crank up the earbuds volume to overcome background noise.
The Jabra Evolve2 Buds too have Active Noise Cancellation making both earbuds ideal for flights and rush hour travels. Each work with different noise cancellation types, pick the setting that you prefer for travel or that suites your relaxation time.
