Has Active Noise Cancellation (Noise Control)
Devialet Gemini 2

JBL Wave Beam ✓
ANC makes use of advanced technology to actively counter noise. ANC works when, it detects and analyzes the sound pattern outside and inside the earbud and then generates a mirror signal to cancel it out. Simply put, it's like taking +1 (sound from your surrounding) then adding -1 (inverted noise) giving zero thus "diluting" the noise.
The Devialet Gemini 2 have Active Noise Cancellation enabling you to listen at lower volume levels, causing less ear fatigue as you don't have to crank up the earbuds volume to overcome background noise.
The JBL Wave Beam too have Active Noise Cancellation making either of the earbuds ideal for flights and morning travels. The Devialet Gemini 2 and JBL Wave Beam operate with different noise cancellation modes, pick the mode that suits your commute or that suites your chill time.
Has Passive Noise Reduction

JBL Wave Beam ✓
The Devialet Gemini 2 sit tightly in place, creating a sound covering that reduces your environment sounds and also prevents the device sound from leaking out .
Both of these devices have passive noise reduction this implies that they tone down ambient noise instead of actively using ANC to cancel it out.
Driver Unit Size
Devialet Gemini 2
10mm
JBL Wave Beam 8mm
Devialet Gemini 2 driver unit is 10mm in diameter, bigger drivers are more powerful, and can produce better bass.
The driver unit is basically a mini speaker that produces sound in the earbuds, the unit size dictates the sound made by the earbuds.
JBL Wave Beam driver unit is 8mm in diameter,
which implies that they have a smaller driver unit than that of Devialet Gemini 2 by 2mm
, many people have a misconception that driver units of a bigger size automatically produce better sound quality.
However, large drivers find it difficult to produce high frequencies so yes, larger drivers can generate louder sound, but this does not mean that they produce better quality sound.
Lowest Frequency
Devialet Gemini 2
5Hz
JBL Wave Beam 20Hz
The Devialet Gemini 2's lowest frequency is at 5Hz, low-frequency response measures if and how well an audio component produces low recognizable frequencies and if it makes any changes to the signal on its way through.
JBL Wave Beam's lowest frequency is at 20Hz, this implies that
Devialet Gemini 2 can produce a juicier bass than the JBL Wave Beam
Highest Frequency
Devialet Gemini 2
20,000Hz
JBL Wave Beam 20,000Hz
Devialet Gemini 2's highest frequency is at 20,000Hz, high-frequency response indicates how well an audio component produces high human frequencies and if it adjustments to the signal while at it.
JBL Wave Beam's highest frequency is at 20,000Hz, this means that
both devices produce equal treble
Sound Pressure Level
Devialet Gemini 2
120dB/mW
JBL Wave Beam 100dB/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 Beam's sound pressure level measurement is 100dB/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.
