Devialet Gemini 2 ✓
ANC uses more advanced kind of tech to reduce ambient sounds. How it works, it detects and analyzes the sound pattern of incoming noise and generates a mirror signal to cancel it out. In simple terms, it's like having +1 (noise) then producing -1 (inverted noise) giving 0 resulting in a reduced level of noise.
Devialet Gemini 2 have Active Noise Cancellation allowing you to listen at lower volume levels, good for your ears since you don't need to crank up the device volume to overcome background sounds.
The JLab Audio Epic Air Sport ANC too have Active Noise Cancellation making either of the devices ideal for plane rides and morning commutes. Each work with different noise cancellation settings, pick the noise cancellation type that suits your travel or that suites your relaxation time.

Driver Unit Size
JLab Audio Epic Air Sport ANC
8mm
Devialet Gemini 2 10mm
The Devialet Gemini 2 driver unit is 10mm in diameter, the bigger the unit the more powerful, therefor producing better bass.
The driver unit is basically a mini speaker that makes sound in the device, its size dictates the sound made by the device.
JLab Audio Epic Air Sport ANC driver unit is 8mm in diameter,
which means that they have a smaller driver unit than that of Devialet Gemini 2 by 2mm
, 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 yes, larger drivers are capable of generating louder sound, but this does not indicate that they produce better quality sound.
Lowest Frequency
JLab Audio Epic Air Sport ANC
20Hz
Devialet Gemini 2 5Hz
Devialet Gemini 2's lowest frequency is at 5Hz, low-frequency response inidcates how well an audio component produces low audible frequencies and if it makes any changes to the signal while at it.
JLab Audio Epic Air Sport ANC's lowest frequency is at 20Hz, this means that
Devialet Gemini 2 can produce a juicier bass than the JLab Audio Epic Air Sport ANC
Highest Frequency
JLab Audio Epic Air Sport ANC
20,000Hz
Devialet Gemini 2 20,000Hz
The Devialet Gemini 2's highest frequency is at 20,000Hz, high-frequency response shows how well an audio component produces high audible frequencies and if it adjustments to the signal while at it.
JLab Audio Epic Air Sport ANC's highest frequency is at 20,000Hz, this means that
both devices produce equal treble
Sound Pressure Level
JLab Audio Epic Air Sport ANC
110dB/mW
Devialet Gemini 2 120dB/mW
SPL, 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.
JLab Audio Epic Air Sport ANC's sound pressure level measurement is 110dB/mW. How loud something is can be taken differently by different persons, so we need to have the means to get a standard measurement of sound level expressed in numerical terms.
