Has Active Noise Cancellation (Noise Control)
Devialet Gemini 2
✓
JBL Endurance Peak 3 ✗
ANC makes use of more advanced kind of tech to actively counter noise. ANC works when, it studies the sound pattern outside and inside the earbud and after generates a mirror signal to cancel it out. Simply put, it's like having +1 (sound from your surrounding) then adding -1 (counter sound by the device) to make zero which results in a reduced level of noise.
Devialet Gemini 2 have ANC allowing you to listen at lower levels of volume, good for your ears since you don't have to crank up the earbuds volume to outcompete background noise.
Has Passive Noise Reduction
Devialet Gemini 2
✓
JBL Endurance Peak 3 ✓
JBL Endurance Peak 3 stay tightly in place, creating an acoustic covering that reduces your environment noise while preventing the device sound from leaking out at the same.
Both of these devices have passive noise reduction which means that they tone down ambient noise instead of actively using ANC to cancel it out.
Driver Unit Size
Devialet Gemini 2
10mm
JBL Endurance Peak 3 10mm
The JBL Endurance Peak 3 have a unit size of 10mm in diameter, bigger drivers are more powerful, therefor producing better bass.
The driver unit is the component that makes sound in the earbuds, the unit size determines the sound made by the device.
Devialet Gemini 2 driver unit is 10mm in diameter,
making both Devialet Gemini 2, and JBL Endurance Peak 3 similar in how loud their sound can get
, many people have a misconception that driver units of a bigger size automatically produce better sound quality.
However, large drivers usually have difficulty producing high frequencies so yeah, larger drivers are capable of generating louder sound, but this does not indicate that they deliver better quality sound.
Lowest Frequency
Devialet Gemini 2
5Hz
JBL Endurance Peak 3 20Hz
The JBL Endurance Peak 3's lowest frequency is at 20Hz, low-frequency response inidcates how well a particular audio component produces low frequencies that can be heard, and if it alters the signal on its way through.
Devialet Gemini 2's lowest frequency is at 5Hz, this means that
Devialet Gemini 2 can produce a juicier bass than the JBL Endurance Peak 3
Highest Frequency
Devialet Gemini 2
20,000Hz
JBL Endurance Peak 3 20,000Hz
The JBL Endurance Peak 3's highest frequency is at 20,000Hz, high-frequency response indicates how well a particular audio component generates high recognizable frequencies and if it makes any changes to the signal on its way through.
Devialet Gemini 2's highest frequency is at 20,000Hz, this means that
both devices generate equal treble
Sound Pressure Level
Devialet Gemini 2
120dB/mW
JBL Endurance Peak 3 102dB/mW
The sound pressure level, is the pressure level of sound, measured in decibels, dB, JBL Endurance Peak 3's measurement is 102dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
Devialet Gemini 2's sound pressure level measurement is 120dB/mW. The sound pressure level, a device is can be considered differently by separate persons, so we need to have the means to get a standard measurement of sound level expressed in numerical terms.
