ANC utilises more advanced technology to actively cancel noise. ANC works when, it detects and analyzes the sound pattern outside and inside the earbud and generates a mirror signal to cancel it out. Simply put, it's like taking +1 (noise) then adding -1 (inverted noise) to make 0 hence "diluting" the noise.
Bose QuietComfort Earbuds 2 have ANC enabling you to listen at lower levels of volume, causing less ear fatigue as you don't need to crank up the device volume to overcome background noise.
Sony WF 1000XM4 too have ANC which makes either of the earbuds ideal for flights and morning commutes. The Bose QuietComfort Earbuds 2 and Sony WF 1000XM4 work with different noise cancellation modes, pick the setting that suits your travel or that enhances your chill time.
