Active noise cancellation uses advanced kind of tech to actively cancel noise. ANC works when, it studies the sound pattern of incoming noise and inverts the soundwaves to cancel it out. In simple terms, it's like having +1 (sound from your surrounding) then adding -1 (inverted noise) giving 0 thus "diluting" the noise.
The Devialet Gemini 2 have ANC enabling you to listen at lower volume levels, causing less ear fatigue as you don't have to crank up the earbuds volume to outcompete background noise.
Technics EAH AZ80 too have ANC making both earbuds ideal for flights and morning commutes. The Devialet Gemini 2 and Technics EAH AZ80 work with different noise cancellation modes, pick the mode that suits your travel or that suites your chill time.

Driver Unit Size
Technics EAH AZ80
10mm
Devialet Gemini 2 10mm
Devialet Gemini 2 driver unit is 10mm in diameter, the bigger the unit the more powerful, and can produce better bass.
The driver unit is basically a mini speaker that makes sound in the device, its size dictates the sound produced by the device.
Technics EAH AZ80 driver unit is 10mm in diameter,
making both devices similar in how loud their sound can get
, as many tend to believe that driver units of a bigger size automatically produce better sound quality.
However, large drivers usually have difficulty producing high frequencies so it's true that, larger drivers can generate louder sound, but this does not mean that they deliver better quality sound.
Lowest Frequency
Technics EAH AZ80
20Hz
Devialet Gemini 2 5Hz
Devialet Gemini 2's lowest frequency is at 5Hz, low-frequency response inidcates how well a particular audio component generates low recognizable frequencies and if it alters the signal while at it.
Technics EAH AZ80's lowest frequency is at 20Hz, this means that
Devialet Gemini 2 can produce a juicier bass than the Technics EAH AZ80
Highest Frequency
Technics EAH AZ80
40,000Hz
Devialet Gemini 2 20,000Hz
The Devialet Gemini 2's highest frequency is at 20,000Hz, high-frequency response indicates how well an audio component generates high audible frequencies and if it adjustments to the signal while at it.
Technics EAH AZ80's highest frequency is at 40,000Hz, this implies that
Technics EAH AZ80 produce a clearer and crispier treble than the Devialet Gemini 2
Sound Pressure Level
Technics EAH AZ80
✗
Devialet Gemini 2 120dB/mW
The sound pressure level, is the pressure level of sound, measured in decibels, dB, Devialet Gemini 2's measurement is 120dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
