ANC makes use of advanced technology to actively counter noise. How it works, it studies the sound pattern of incoming noise and then inverts the soundwaves to cancel it out. In simple terms, it's like having +1 (sound from your surrounding) and adding -1 (counter sound by the device) to make zero which results in a reduced level of noise.
Google Pixel Buds Pro have ANC enabling you to listen at lower volume levels, causing less ear fatigue since you don't need to crank up the earbuds volume to outcompete background noise.
The Bose QuietComfort Earbuds 2 too have ANC making either of the earbuds ideal for flights and rush hour travels. Each operate with different noise cancellation modes, pick the mode that suits your travel or that suites your chill time.
