Has Active Noise Cancellation (Noise Control)
JBL Wave Buds
✓
Devialet Gemini 2 ✓
Active noise cancellation utilises more advanced kind of tech to actively cancel noise. How it works, it listens to the sound pattern outside and inside the earbud and generates a mirror signal to counter it. Simply put, it's like taking +1 (sound from your surrounding) then producing -1 (inverted noise) to make zero resulting in a reduced level of noise.
The Devialet Gemini 2 have Active Noise Cancellation allowing you to listen at lower volume levels, causing less ear fatigue as you don't have to crank up the device volume to overcome background noise.
JBL Wave Buds too have Active Noise Cancellation making either of the earbuds ideal for flights and morning travels. Each operate with different noise cancellation settings, pick the noise cancellation type that you prefer for travel or that suites your chill time.
Has Passive Noise Reduction

Devialet Gemini 2 ✓
Devialet Gemini 2 stay tightly in place, creating a sound covering that tones down your environment sounds and also prevents the earbuds voice audio from leaking out .
Both of these devices have passive noise reduction which implies that they tone down ambient noise instead of actively using technology to cancel it out.
Driver Unit Size
JBL Wave Buds
8mm
Devialet Gemini 2 10mm
The Devialet Gemini 2 have a unit size of 10mm in diameter, bigger drivers are more powerful, and can produce better bass.
A driver unit is the component that makes sound in the earbuds, its size dictates the sound produced by the earbuds.
JBL Wave Buds 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 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
JBL Wave Buds
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 on its way through.
JBL Wave Buds's lowest frequency is at 20Hz, this means that
Devialet Gemini 2 produce a juicier bass than the JBL Wave Buds
Highest Frequency
JBL Wave Buds
20,000Hz
Devialet Gemini 2 20,000Hz
The Devialet Gemini 2's highest frequency is at 20,000Hz, high-frequency response shows how well a particular audio component generates high audible frequencies and if it makes any changes to the signal on its way through.
JBL Wave Buds's highest frequency is at 20,000Hz, this means that
both devices produce equal treble
Sound Pressure Level
JBL Wave Buds
100dB/mW
Devialet Gemini 2 120dB/mW
The sound pressure level, is the level of pressure of sound, 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.
JBL Wave Buds's sound pressure level measurement is 100dB/mW. The sound pressure level, something is can be perceived differently by separate people, so we need to have the means to get an objective measurement of sound level expressed in numerical terms.
