ANC uses advanced technology to actively counter noise.
How it works, it detects and analyzes the sound pattern of incoming noise and then inverts the soundwaves to cancel it out. In simple terms, it's like having +1 (sound from your surrounding) and adding -1 (counter sound by the device) to make zero which results in a reduced level of noise.
Technics EAH AZ80 have Active Noise Cancellation allowing you to listen at lower volume levels, good for your ears since you don't have to crank up the device volume to overcome background sounds.

which implies that they have a smaller driver unit than that of Technics EAH AZ80 by 0.7mm
, many people have a misconception that driver units of a bigger size automatically produce better sound quality.
However, large drivers usually have difficulty producing high frequencies so yes, larger drivers are capable of generating louder sound, but this does not indicate that they produce better quality sound. The Technics EAH AZ80's lowest frequency is at 20Hz, low-frequency response inidcates how well a particular audio component generates low recognizable frequencies and if it makes any changes to the signal on its way through. Bose QuietComfort Earbuds 2's lowest frequency is at 20Hz, this means that
both devices produce equal bass
Technics EAH AZ80's highest frequency is at 40,000Hz, high-frequency response tells how well a particular audio device produces high audible frequencies and if it changes to the signal on its way through.
Bose QuietComfort Earbuds 2's highest frequency is at 20,000Hz, this means that
Technics EAH AZ80 can produce a clearer and crispier treble than the Bose QuietComfort Earbuds 2
