Has Active Noise Cancellation (Noise Control)

Ultimate Ears Drops ✗
ANC uses advanced technology to reduce unwanted ambient sounds. ANC works when, it detects and analyzes the sound pattern outside and inside the earbud and generates a mirror signal to cancel it out. Simply put, it's like taking +1 (sound from your surrounding) then producing -1 (inverted noise) giving zero which results in a reduced level of noise.
Devialet Gemini have ANC enabling you to listen at lower volume levels, causing less ear fatigue since you don't have to crank up the earbuds volume to overcome background noise.
Has Passive Noise Reduction
Devialet Gemini
✓
Ultimate Ears Drops ✓
The Ultimate Ears Drops stay tightly in place, this creates a sound seal that reduces background noise and also prevents the earbuds sound from leaking out at the same.
Both of these devices have passive noise reduction which means that both tone down ambient noise instead of actively using technology 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, the bigger the unit the more powerful, therefor producing better bass.
A driver unit is the component that makes sound in the earbuds, the unit size dictates the sound made by the device.
Devialet Gemini driver unit is 10mm in diameter,
making them have a larger driver unit than that of Ultimate Ears Drops by 0.8mm
, 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 it's true that, larger drivers are capable of generating louder sound, but this does not mean that they produce better quality sound.
Lowest Frequency
Devialet Gemini
5hz
Ultimate Ears Drops 20hz
The Ultimate Ears Drops's lowest frequency is at 20Hz, low-frequency response inidcates how well a particular audio component generates low frequencies that can be heard, and if it alters the signal while at it.
Devialet Gemini's lowest frequency is at 5Hz, this implies that
Devialet Gemini produce a juicier bass than the Ultimate Ears Drops
Highest Frequency
Devialet Gemini
20,000hz
Ultimate Ears Drops 20,000hz
Ultimate Ears Drops's highest frequency is at 20,000Hz, high-frequency response measures if and how well an audio component produces high audible frequencies and if it makes any adjustments to the signal while at it.
Devialet Gemini's highest frequency is at 20,000Hz, this implies that
both devices generate equal treble
Sound Pressure Level
Devialet Gemini
94db/mw
Ultimate Ears Drops 110db/mw
The sound pressure level, is the pressure level 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 considered differently by different people, so we need to have the means to get a standard measurement of sound level expressed in numerical terms.
