Active noise cancellation uses advanced technology to reduce ambient sounds. ANC works when, it detects and analyzes the sound pattern outside and inside the earbud and inverts the soundwaves to counter it. Simply put, it's like taking +1 (sound from your surrounding) and adding -1 (counter sound by the device) to make 0 resulting in a reduced level of noise.
Bose QuietComfort Earbuds II have ANC allowing you to listen at lower volume levels, causing less ear fatigue as you don't need to crank up the device volume to overcome background noise.
Sennheiser Momentum True Wireless 3 too have ANC making both devices ideal for flights and rush hour commutes. The Bose QuietComfort Earbuds II and Sennheiser Momentum True Wireless 3 operate with different noise cancellation types, pick the mode that you prefer for commute or that enhances your relaxation time.
