✓
Technics EAH AZ60 ✓
Active noise cancellation uses more advanced kind of tech to actively counter noise. How it works, it studies the sound pattern outside and inside the earbud and after inverts the soundwaves to cancel it out. In simple terms, it's like having +1 (noise) and adding -1 (counter sound by the device) to make zero resulting in a reduced level of noise.
Technics EAH AZ60 have ANC allowing you to listen at lower volume levels, causing less ear fatigue since you don't need to crank up the device volume to outcompete background sounds.
The Sony WF 1000XM4 too have ANC making either of the devices ideal for plane rides and morning commutes. The Technics EAH AZ60 and Sony WF 1000XM4 operate with different noise cancellation types, pick the noise cancellation type that suits your commute or that enhances your chill time.

which means that they have a smaller driver unit than that of Technics EAH AZ60 by 2mm
, many people have a misconception that driver units of a bigger size automatically produce better sound quality.
