Has Active Noise Cancellation (Noise Control)
JBL Wave Buds
✓
Devialet Gemini ✓
Active noise cancellation utilises advanced technology to actively counter noise. How it works, it detects and analyzes the sound pattern outside and inside the earbud and after inverts the soundwaves to counter it. Simply put, it's like having +1 (noise) and producing -1 (inverted noise) to make zero which results in a reduced level of noise.
Devialet Gemini have ANC allowing 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 noise.
The JBL Wave Buds too have Active Noise Cancellation making either of the devices ideal for plane rides and rush hour commutes. The Devialet Gemini and JBL Wave Buds work with different noise cancellation settings, pick the mode that suits your travel or that suites your chill time.
Has Passive Noise Reduction
JBL Wave Buds
✓
Devialet Gemini ✓
Devialet Gemini stay tightly in place, creating an acoustic seal that tones down your environment sounds well as preventing the earbuds sound from leaking out .
Both of these devices have passive noise reduction this implies that they tone down ambient noise without using ANC to cancel it out.
Driver Unit Size
JBL Wave Buds
8mm
Devialet Gemini 10mm
Devialet Gemini have a unit size of 10mm in diameter, the bigger the unit the more powerful, and can produce better bass.
A driver unit is basically a mini speaker that makes sound in the earbuds, the unit size determines the sound made by the device.
JBL Wave Buds driver unit is 8mm in diameter,
which implies that they have a smaller driver unit than that of Devialet Gemini by 2mm
, as many tend to believe 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 are capable of generating louder sound, but this does not indicate that they produce better quality sound.
Lowest Frequency
JBL Wave Buds
20Hz
Devialet Gemini 5Hz
Devialet Gemini's lowest frequency is at 5Hz, low-frequency response measures if and how well a particular audio device generates low frequencies that can be heard, and if it alters the signal while at it.
JBL Wave Buds's lowest frequency is at 20Hz, this implies that
Devialet Gemini can make sound with a juicier bass than the JBL Wave Buds
Highest Frequency
JBL Wave Buds
20000Hz
Devialet Gemini 20000Hz
Devialet Gemini's highest frequency is at 20000Hz, high-frequency response shows how well an audio device makes high human frequencies and if it adjustments to the signal while at it.
JBL Wave Buds's highest frequency is at 20000Hz, this means that
both devices can generate equal treble
Sound Pressure Level
JBL Wave Buds
100dB/mW
Devialet Gemini 94dB/mW
SPL, 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 Wave Buds's sound pressure level measurement is 100dB/mW. How loud a device is can be considered differently by different persons, so we need to have a way of getting an objective measurement of sound level expressed in numerical terms.
