Has Active Noise Cancellation (Noise Control)
Devialet Gemini
✓
JLab Go Air ✗
ANC uses advanced kind of tech to reduce unwanted ambient sounds. How it works, it listens to the sound pattern outside and inside the earbud and then inverts the soundwaves to counter it. Simply put, it's like having +1 (sound from your surrounding) and producing -1 (counter sound by the device) to make zero resulting in a reduced level of noise.
Devialet Gemini have Active Noise Cancellation allowing you to listen at lower volume levels, causing less ear fatigue as you don't have to crank up the device volume to outcompete background noise.
Has Passive Noise Reduction
Devialet Gemini
✓
JLab Go Air ✓
The Devialet Gemini stay tightly in place, this creates an acoustic seal that reduces background sounds well as preventing the device sound from leaking out at the same.
Both JLab Go Air, and Devialet Gemini have passive noise reduction this implies that they limit ambient noise without using technology to cancel it out.
Driver Unit Size
Devialet Gemini
10mm
JLab Go Air 8mm
The Devialet Gemini have a unit size of 10mm in diameter, bigger drivers are more powerful, and can produce better bass.
The driver unit is basically a mini speaker that makes sound in the device, its size dictates the sound produced by the device.
JLab Go Air driver unit is 8mm in diameter,
which means 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 are capable of generating louder sound, but this does not indicate that they produce better quality sound.
Lowest Frequency
Devialet Gemini
5Hz
JLab Go Air 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.
JLab Go Air's lowest frequency is at 20Hz, this means that
Devialet Gemini can make sound with a juicier bass than the JLab Go Air
Highest Frequency
Devialet Gemini
20000Hz
JLab Go Air 20000Hz
The Devialet Gemini's highest frequency is at 20000Hz, high-frequency response tells how well an audio component makes high audible frequencies and if it makes any adjustments to the signal on its way through.
JLab Go Air's highest frequency is at 20000Hz, this means that
both devices can generate equal treble
Sound Pressure Level
Devialet Gemini
94dB/mW
JLab Go Air 103dB/mW
The sound pressure level, is the pressure level 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. The sound pressure level, a device is can be taken differently by separate persons, so we need to have a way of getting an objective measurement of sound level expressed in numerical terms.
Has A Neodymium Magnet
Devialet Gemini
✗
JLab Go Air ✓
JLab Go Air have neodymium magnets, if used in audio devices produce a higher sensitivity and substantial sound output using less power to do so. They can help generate music at quite a high SPL, using high magnetic flux.
