Has Active Noise Cancellation (Noise Control)

Devialet Gemini 2 ✓

JLab Go Air ✗

ANC utilises advanced technology to actively counter noise. How it works, it listens to the sound pattern outside and inside the earbud and then inverts the soundwaves to counter it. In simple terms, it's like taking +1 (noise) then producing -1 (counter sound by the device) giving 0 which results in a reduced level of noise.

Devialet Gemini 2 have ANC enabling you to listen at lower levels of volume, good for your ears as you don't need to crank up the device volume to outcompete background sounds.

Has Passive Noise Reduction

Devialet Gemini 2 ✓

JLab Go Air ✓

Devialet Gemini 2 stay tightly in place, creating an acoustic seal that tones down background noise while preventing the earbuds sound from leaking out .

Both JLab Go Air, and Devialet Gemini 2 have passive noise reduction which implies that both limit ambient noise without using technology to cancel it out.

Driver Unit Size

Devialet Gemini 2 10mm

JLab Go Air 8mm

Devialet Gemini 2 driver unit is 10mm in diameter, bigger drivers are more powerful, therefor producing better bass. The driver unit is basically a mini speaker that makes sound in the earbuds, its size corellates with the loudness of the device.

JLab Go Air driver unit is 8mm in diameter, which implies that they have a smaller driver unit than that of Devialet Gemini 2 by 2mm , a common assumption 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 are capable of generating louder sound, but this does not imply that they produce better quality sound.

Lowest Frequency

Devialet Gemini 2 5Hz

JLab Go Air 20Hz

Devialet Gemini 2's lowest frequency is at 5Hz, low-frequency response measures if and how well a particular audio device produces low recognizable frequencies and if it makes any changes to the signal on its way through.

JLab Go Air's lowest frequency is at 20Hz, this means that Devialet Gemini 2 produce a juicier bass than the JLab Go Air

Highest Frequency

Devialet Gemini 2 20,000Hz

JLab Go Air 20,000Hz

The Devialet Gemini 2's highest frequency is at 20,000Hz, high-frequency response tells how well a particular audio device makes high human frequencies and if it makes any adjustments to the signal on its way through.

JLab Go Air's highest frequency is at 20,000Hz, this implies that both devices can generate equal treble

Sound Pressure Level

Devialet Gemini 2 120dB/mW

JLab Go Air 103dB/mW

SPL, is the level of pressure 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 Go Air's sound pressure level measurement is 103dB/mW. The sound pressure level, a device is can be perceived differently by separate persons, so we need to have the means to get an objective measurement of sound level expressed in numerical terms.
