Has Active Noise Cancellation (Noise Control)
Devialet Gemini

JBL Tune 225TWS ✗
ANC uses more advanced kind of tech to actively cancel noise. ANC works when, it detects and analyzes the sound pattern outside and inside the earbud and inverts the soundwaves to counter it. In simple terms, it's like having +1 (noise) and adding -1 (counter sound by the device) to make 0 which results in a reduced level of noise.
The Devialet Gemini have Active Noise Cancellation enabling you to listen at lower volume levels, good for your ears since you don't have to crank up the earbuds volume to outcompete background sounds.
Has Passive Noise Reduction

JBL Tune 225TWS ✓
The Devialet Gemini sit well in place, this creates an acoustic covering that tones down background sounds and also prevents the earbuds music from leaking out at the same.
Both of these devices have passive noise reduction which means that both tone down ambient noise without using technology to cancel it out.
Driver Unit Size
Devialet Gemini
10mm
JBL Tune 225TWS 12mm
The Devialet Gemini have a unit size of 10mm in diameter, bigger drivers are more powerful, and can produce better bass.
A driver unit is basically a mini speaker that produces sound in the earbuds, the unit size determines the sound produced by the earbuds.
JBL Tune 225TWS driver unit is 12mm in diameter,
making them have a larger driver unit than that of Devialet Gemini 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 yes, larger drivers are capable of generating louder sound, but this does not mean that they deliver better quality sound.
Lowest Frequency
Devialet Gemini
5Hz
JBL Tune 225TWS 20Hz
The Devialet Gemini's lowest frequency is at 5Hz, low-frequency response measures if and how well an audio component generates low frequencies that can be heard, and if it alters the signal while at it.
JBL Tune 225TWS's lowest frequency is at 20Hz, this implies that
Devialet Gemini produce a juicier bass than the JBL Tune 225TWS
Highest Frequency
Devialet Gemini
20000Hz
JBL Tune 225TWS 20000Hz
The Devialet Gemini's highest frequency is at 20000Hz, high-frequency response measures if and how well an audio component makes high recognizable frequencies and if it adjustments to the signal while at it.
JBL Tune 225TWS's highest frequency is at 20000Hz, this means that
both devices generate equal treble
Sound Pressure Level
Devialet Gemini
94dB/mW
JBL Tune 225TWS 105dB/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 Tune 225TWS's sound pressure level measurement is 105dB/mW. The sound pressure level, something is can be taken differently by separate people, so we need to have the means to get a standard measurement of sound level expressed in numerical terms.
