Active noise cancellation makes use of advanced technology to reduce unwanted ambient sounds. ANC works when, it detects and analyzes the sound pattern outside and inside the earbud and inverts the soundwaves to counter it. In simple terms, it's like having +1 (sound from your surrounding) then adding -1 (inverted noise) giving 0 hence "diluting" the noise.
The Samsung Galaxy Buds 2 Pro have Active Noise Cancellation allowing you to listen at lower levels of volume, causing less ear fatigue since you don't need to crank up the earbuds volume to overcome background noise.
The Bowers & Wilkins PI7 too have ANC making both devices ideal for flights and morning travels. Each operate with different noise cancellation settings, pick the setting that suits your travel or that enhances your relaxation time.
