Active noise cancellation makes use of advanced technology to reduce unwanted ambient sounds. ANC works when, it detects and analyzes the sound pattern outside and inside the earbud and after generates a mirror signal to cancel it out. Simply put, it's like having +1 (sound from your surrounding) and adding -1 (counter sound by the device) to make 0 which results in a reduced level of noise.
The Devialet Gemini have Active Noise Cancellation enabling you to listen at lower levels of volume, causing less ear fatigue since you don't have to crank up the device volume to overcome background sounds.
The OnePlus Buds Z2 too have ANC which makes either of the devices ideal for flights and morning travels. The Devialet Gemini and OnePlus Buds Z2 operate with different noise cancellation types, pick the noise cancellation type that you prefer for travel or that suites your chill time.

Driver Unit Size
Devialet Gemini
10mm
OnePlus Buds Z2 11mm
The Devialet Gemini have a unit size of 10mm in diameter, the bigger the unit the more powerful, therefor producing better bass.
A driver unit is the component that produces sound in the earbuds, the unit size corellates with the sound produced by the device.
OnePlus Buds Z2 driver unit is 11mm in diameter,
making them have a larger driver unit than that of Devialet Gemini by 1mm
, as many tend to believe that driver units of a bigger size automatically produce better sound quality.
However, large drivers find it difficult to produce high frequencies so it's true that, larger drivers are capable of generating louder sound, but this does not mean that they deliver better quality sound.
Lowest Frequency
Devialet Gemini
5Hz
OnePlus Buds Z2 20Hz
Devialet Gemini's lowest frequency is at 5Hz, low-frequency response measures if and how well a particular audio device generates low frequencies that can be heard, and if it alters the signal on its way through.
OnePlus Buds Z2's lowest frequency is at 20Hz, this implies that
Devialet Gemini produce a juicier bass than the OnePlus Buds Z2
Highest Frequency
Devialet Gemini
20000Hz
OnePlus Buds Z2 20000Hz
Devialet Gemini's highest frequency is at 20000Hz, high-frequency response indicates how well an audio component makes high recognizable frequencies and if it makes any changes to the signal on its way through.
OnePlus Buds Z2's highest frequency is at 20000Hz, this implies that
both devices generate equal treble
Sound Pressure Level
Devialet Gemini
94dB/mW
OnePlus Buds Z2 ✗
SPL, is the pressure level of sound, in decibels, dB, Devialet Gemini's measurement is 94dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
