Has Active Noise Cancellation (Noise Control)
Devialet Gemini
✓
Ultimate Ears Drops ✗
Active noise cancellation utilises advanced kind of tech to actively counter noise. How it works, it studies the sound pattern outside and inside the earbud and after inverts the soundwaves to counter it. Simply put, it's like having +1 (noise) then producing -1 (inverted noise) to make zero hence "diluting" the noise.
The Devialet Gemini have ANC enabling you to listen at lower levels of volume, causing less ear fatigue as you don't have to crank up the earbuds volume to overcome background sounds.
Has Passive Noise Reduction

Ultimate Ears Drops ✓
Ultimate Ears Drops stay tightly in place, creating an acoustic covering that tones down your environment sounds and also prevents the earbuds sound from leaking out .
Both Devialet Gemini, and Ultimate Ears Drops 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
10mm
Ultimate Ears Drops 9.2mm
Ultimate Ears Drops have a unit size of 9.2mm in diameter, bigger drivers are more powerful, therefor producing better bass.
The driver unit is basically a mini speaker that makes sound in the device, its size determines the loudness of the earbuds.
Devialet Gemini driver unit is 10mm in diameter,
making them have a larger driver unit than that of Ultimate Ears Drops by 0.8mm
, many people have a misconception 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 can generate louder sound, but this does not mean that they deliver better quality sound.
Lowest Frequency
Devialet Gemini
5Hz
Ultimate Ears Drops 20Hz
Ultimate Ears Drops's lowest frequency is at 20Hz, low-frequency response measures if and how well an audio device produces low audible frequencies and if it makes any changes to the signal on its way through.
Devialet Gemini's lowest frequency is at 5Hz, this means that
Devialet Gemini produce a juicier bass than the Ultimate Ears Drops
Highest Frequency
Devialet Gemini
20000Hz
Ultimate Ears Drops 20000Hz
Ultimate Ears Drops's highest frequency is at 20000Hz, high-frequency response tells how well an audio component makes high audible frequencies and if it adjustments to the signal while at it.
Devialet Gemini's highest frequency is at 20000Hz, this implies that
both devices can produce equal treble
Sound Pressure Level
Devialet Gemini
94dB/mW
Ultimate Ears Drops 110dB/mW
SPL, is the level of pressure of sound, in decibels, dB, Ultimate Ears Drops's measurement is 110dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
Devialet Gemini's sound pressure level measurement is 94dB/mW. The sound pressure level, something is can be taken differently by separate people, so we need to have a way of getting a standard measurement of sound level expressed in numerical terms.
