Has Active Noise Cancellation (Noise Control)
Devialet Gemini
✓
JLab Go Air ✗
Active noise cancellation uses more advanced kind of tech to actively counter noise. ANC works when, it detects and analyzes the sound pattern of incoming noise and generates a mirror signal 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 thus "diluting" the noise.
The Devialet Gemini have Active Noise Cancellation enabling you to listen at lower levels of volume, good for your ears as you don't need to crank up the earbuds volume to outcompete background sounds.
Has Passive Noise Reduction
Devialet Gemini
✓
JLab Go Air ✓
The Devialet Gemini stay well in place, creating an acoustic seal that tones down background noise and also prevents the earbuds music from leaking out at the same.
Both JLab Go Air, and Devialet Gemini have passive noise reduction which implies that they limit ambient noise instead of actively using ANC to cancel it out.
Driver Unit Size
Devialet Gemini
10mm
JLab Go Air 8mm
Devialet Gemini driver unit is 10mm in diameter, the bigger the unit the more powerful, therefor producing better bass.
A driver unit is the component that makes sound in the device, the unit size corellates with the sound made by the earbuds.
JLab Go Air driver unit is 8mm in diameter,
which implies that they have a smaller driver unit than that of Devialet Gemini by 2mm
, 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 yes, larger drivers can generate louder sound, but this does not indicate that they produce better quality sound.
Lowest Frequency
Devialet Gemini
5hz
JLab Go Air 20hz
Devialet Gemini's lowest frequency is at 5Hz, low-frequency response measures if and how well a particular audio component produces low audible frequencies and if it makes any changes to the signal while at it.
JLab Go Air's lowest frequency is at 20Hz, this means that
Devialet Gemini can produce a juicier bass than the JLab Go Air
Highest Frequency
Devialet Gemini
20,000hz
JLab Go Air 20,000hz
The Devialet Gemini's highest frequency is at 20,000Hz, high-frequency response indicates how well an audio device generates high recognizable frequencies and if it adjustments to the signal while at it.
JLab Go Air's highest frequency is at 20,000Hz, this means that
both devices can produce equal treble
Sound Pressure Level
Devialet Gemini
94db/mw
JLab Go Air 103db/mw
SPL, 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.
JLab Go Air's sound pressure level measurement is 103dB/mW. How loud a device is can be considered differently by different people, so we need to have the means to get an objective measurement of sound level expressed in numerical terms.
Has A Neodymium Magnet
Devialet Gemini
✗
JLab Go Air ✓
The JLab Go Air have neodymium magnets, if used in audio devices produce a higher sensitivity and substantial sound output while using less power. They can help produce music at quite a high sound pressure level, using high magnetic flux.
