ANC works when, it detects and analyzes the sound pattern outside and inside the earbud and after inverts the soundwaves to counter it. In simple terms, it's like taking +1 (sound from your surrounding) then adding -1 (counter sound by the device) to make 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 as you don't need to crank up the earbuds volume to overcome background noise.
