Active noise cancellation uses more advanced kind of tech to reduce unwanted ambient sounds. How it works, it listens to the sound pattern of incoming noise and after generates a mirror signal to cancel it out. In simple terms, it's like having +1 (noise) then producing -1 (counter sound by the device) to make zero which results in a reduced level of noise.
The Technics EAH AZ80 have Active Noise Cancellation allowing you to listen at lower levels of volume, causing less ear fatigue as you don't need to crank up the earbuds volume to outcompete background sounds.
Bose QuietComfort Earbuds 2 too have ANC which makes both earbuds ideal for flights and rush hour commutes. Each work with different noise cancellation types, pick the mode that you prefer for travel or that suites your chill time.
