ANC makes use of advanced technology to actively cancel noise. ANC works when, it detects and analyzes the sound pattern outside and inside the earbud and then inverts the soundwaves to cancel it out. Simply put, it's like having +1 (noise) then producing -1 (inverted noise) to make zero thus "diluting" the noise.
Sennheiser Momentum True Wireless 4 have ANC allowing you to listen at lower levels of volume, causing less ear fatigue since you don't have to crank up the earbuds volume to overcome background noise.
Beats Studio Buds too have Active Noise Cancellation making either of the earbuds ideal for flights and rush hour commutes. Each work with different noise cancellation modes, pick the setting that suits your commute or that suites your chill time.
