Has Active Noise Cancellation (Noise Control)
Devialet Gemini
✓
Jabra Elite 7 Pro ✓
Active noise cancellation utilises advanced technology to reduce ambient sounds. ANC works when, it detects and analyzes the sound pattern outside and inside the earbud and generates a mirror signal to counter it. In simple terms, it's like having +1 (noise) and producing -1 (inverted noise) giving 0 resulting in a reduced level of noise.
The Devialet Gemini have ANC enabling you to listen at lower volume levels, good for your ears since you don't have to crank up the earbuds volume to overcome background sounds.
The Jabra Elite 7 Pro too have Active Noise Cancellation which makes either of the devices ideal for flights and morning travels. Each operate with different noise cancellation settings, pick the mode that you prefer for commute or that enhances your relaxation time.

Driver Unit Size
Devialet Gemini
10mm
Jabra Elite 7 Pro 6mm
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 device, its size corellates with the sound produced by the device.
Jabra Elite 7 Pro driver unit is 6mm in diameter,
which implies that they have a smaller driver unit than that of Devialet Gemini by 4mm
, as many tend to believe 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 deliver better quality sound.
Lowest Frequency
Devialet Gemini
5Hz
Jabra Elite 7 Pro 20Hz
Devialet Gemini's lowest frequency is at 5Hz, low-frequency response inidcates how well a particular audio device produces low audible frequencies and if it alters the signal on its way through.
Jabra Elite 7 Pro's lowest frequency is at 20Hz, this means that
Devialet Gemini make sound with a juicier bass than the Jabra Elite 7 Pro
Highest Frequency
Devialet Gemini
20000Hz
Jabra Elite 7 Pro 20000Hz
Devialet Gemini's highest frequency is at 20000Hz, high-frequency response measures if and how well a particular audio device generates high audible frequencies and if it makes any changes to the signal while at it.
Jabra Elite 7 Pro's highest frequency is at 20000Hz, this implies that
both devices produce equal treble
Sound Pressure Level
Devialet Gemini
94dB/mW
Jabra Elite 7 Pro ✗
SPL, 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.
