Active noise cancellation utilises more advanced technology to reduce ambient sounds. How it works, it detects and analyzes the sound pattern outside and inside the earbud and after inverts the soundwaves to cancel it out. In simple terms, it's like taking +1 (sound from your surrounding) then producing -1 (inverted noise) to make zero hence "diluting" the noise.
Nokia Clarity Earbuds 2 Pro have ANC allowing you to listen at lower levels of volume, good for your ears as you don't need to crank up the earbuds volume to outcompete background sounds.
Bowers & Wilkins PI7 too have ANC making either of the devices ideal for flights and rush hour commutes. The Nokia Clarity Earbuds 2 Pro and Bowers & Wilkins PI7 work with different noise cancellation settings, pick the mode that suits your commute or that suites your relaxation time.
