ANC utilises more advanced technology to reduce unwanted ambient sounds. ANC works when, it detects and analyzes the sound pattern outside and inside the earbud and generates a mirror signal to cancel it out. In simple terms, it's like taking +1 (sound from your surrounding) then adding -1 (inverted noise) giving zero which results in a reduced level of noise.
Sennheiser Momentum True Wireless 4 have Active Noise Cancellation enabling you to listen at lower levels of volume, causing less ear fatigue since you don't need to crank up the earbuds volume to outcompete background noise.
