Has Active Noise Cancellation (Noise Control)
JBL Live Pro 2
✓
Devialet Gemini ✓
Active noise cancellation utilises advanced technology to reduce unwanted ambient sounds. How it works, it listens to the sound pattern of incoming noise and after inverts the soundwaves to counter it. Simply put, it's like taking +1 (noise) then adding -1 (counter sound by the device) giving zero therefore "diluting" the noise.
Devialet Gemini have ANC enabling you to listen at lower levels of volume, good for your ears since you don't need to crank up the earbuds volume to outcompete background sounds.
The JBL Live Pro 2 too have Active Noise Cancellation which makes either of the devices ideal for flights and rush hour travels. The Devialet Gemini and JBL Live Pro 2 work with different noise cancellation settings, pick the setting that suits your travel or that enhances your chill time.
Has Passive Noise Reduction
JBL Live Pro 2
✓
Devialet Gemini ✓
The Devialet Gemini sit tightly in place, this creates a sound seal that reduces your environment sounds while preventing the earbuds sound from leaking out at the same.
Both of these devices have passive noise reduction which implies that both reduce ambient noise without using ANC to cancel it out.
Driver Unit Size
JBL Live Pro 2
11mm
Devialet Gemini 10mm
Devialet Gemini have a unit size of 10mm in diameter, the bigger the unit the more powerful, therefor producing better bass.
A driver unit is basically a mini speaker that produces sound in the earbuds, its size determines the sound produced by the device.
JBL Live Pro 2 driver unit is 11mm in diameter,
making them have a larger driver unit than that of Devialet Gemini by 1mm
, 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 can generate louder sound, but this does not imply that they produce better quality sound.
Lowest Frequency
JBL Live Pro 2
20Hz
Devialet Gemini 5Hz
The Devialet Gemini's lowest frequency is at 5Hz, low-frequency response inidcates how well an audio component produces low frequencies that can be heard, and if it makes any changes to the signal on its way through.
JBL Live Pro 2's lowest frequency is at 20Hz, this means that
Devialet Gemini make sound with a juicier bass than the JBL Live Pro 2
Highest Frequency
JBL Live Pro 2
20000Hz
Devialet Gemini 20000Hz
Devialet Gemini's highest frequency is at 20000Hz, high-frequency response indicates how well an audio device produces high human frequencies and if it changes to the signal while at it.
JBL Live Pro 2's highest frequency is at 20000Hz, this implies that
both devices can produce equal treble
Sound Pressure Level
JBL Live Pro 2
93dB/mW
Devialet Gemini 94dB/mW
The sound pressure level, is the level of pressure of sound, measured 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 Live Pro 2's sound pressure level measurement is 93dB/mW. The sound pressure level, something is can be considered differently by different persons, so we need to have a way of getting a standard measurement of sound level expressed in numerical terms.
