Active noise cancellation uses more advanced technology to reduce ambient sounds. ANC works when, it detects and analyzes the sound pattern outside and inside the earbud and after generates a mirror signal to counter it. Simply put, it's like taking +1 (sound from your surrounding) then adding -1 (inverted noise) to make 0 which results in a reduced level of noise.
Technics EAH AZ80 have Active Noise Cancellation allowing you to listen at lower volume levels, causing less ear fatigue since you don't need to crank up the device volume to overcome background noise.
OnePlus Buds Pro 2 too have ANC making either of the devices ideal for flights and rush hour commutes. The Technics EAH AZ80 and OnePlus Buds Pro 2 operate with different noise cancellation settings, pick the mode that suits your commute or that enhances your relaxation time.
