ANC utilises more advanced kind of tech to actively cancel noise. ANC works when, it studies the sound pattern of incoming noise and inverts the soundwaves to counter it. In simple terms, it's like having +1 (noise) then adding -1 (inverted noise) to make 0 hence "diluting" the noise.
OnePlus Buds Z2 have Active Noise Cancellation allowing you to listen at lower volume levels, causing less ear fatigue as you don't have to crank up the device volume to outcompete background sounds.
The Bose QuietComfort Earbuds II too have ANC which makes either of the devices ideal for plane rides and morning travels. The OnePlus Buds Z2 and Bose QuietComfort Earbuds II operate with different noise cancellation types, pick the noise cancellation type that you prefer for travel or that suites your chill time.
