Has Active Noise Cancellation (Noise Control)
Devialet Gemini
✓
JBL Reflect Aero TWS ✓
Active noise cancellation makes use of more advanced kind of tech to actively cancel noise. How it works, it detects and analyzes the sound pattern of incoming noise and then inverts the soundwaves to counter it. In simple terms, it's like taking +1 (sound from your surrounding) and adding -1 (counter sound by the device) giving 0 therefore "diluting" the noise.
The Devialet Gemini have ANC enabling you to listen at lower volume levels, causing less ear fatigue as you don't need to crank up the device volume to overcome background noise.
The JBL Reflect Aero TWS too have ANC making both earbuds ideal for flights and rush hour commutes. Each work with different noise cancellation types, pick the mode that suits your commute or that enhances your chill time.
Has Passive Noise Reduction

JBL Reflect Aero TWS ✓
Devialet Gemini sit tightly in place, this creates an acoustic seal that reduces your environment noise and also prevents the device music from leaking out at the same.
Both of these devices have passive noise reduction this implies that both limit ambient noise instead of actively using ANC to cancel it out.
Driver Unit Size
Devialet Gemini
10mm
JBL Reflect Aero TWS 6.8mm
Devialet Gemini 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 device, the unit size dictates the loudness of the earbuds.
JBL Reflect Aero TWS driver unit is 6.8mm in diameter,
which means that they have a smaller driver unit than that of Devialet Gemini by 3.2mm
, 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 can generate louder sound, but this does not mean that they produce better quality sound.
Lowest Frequency
Devialet Gemini
5hz
JBL Reflect Aero TWS 20hz
Devialet Gemini's lowest frequency is at 5Hz, low-frequency response measures if and how well an audio component produces low frequencies that can be heard, and if it makes any changes to the signal while at it.
JBL Reflect Aero TWS's lowest frequency is at 20Hz, this means that
Devialet Gemini can produce a juicier bass than the JBL Reflect Aero TWS
Highest Frequency
Devialet Gemini
20,000hz
JBL Reflect Aero TWS 20,000hz
The Devialet Gemini's highest frequency is at 20,000Hz, high-frequency response shows how well a particular audio component produces high human frequencies and if it changes to the signal on its way through.
JBL Reflect Aero TWS's highest frequency is at 20,000Hz, this means that
both devices can produce equal treble
Sound Pressure Level
Devialet Gemini
94db/mw
JBL Reflect Aero TWS 99db/mw
The sound pressure level, is the level of pressure 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.
JBL Reflect Aero TWS's sound pressure level measurement is 99dB/mW. How loud something is can be considered differently by different people, so we need to have a way of getting a standard measurement of sound level expressed in numerical terms.
