Has Active Noise Cancellation (Noise Control)

Bang & Olufsen Beoplay EX ✓
ANC uses advanced technology to reduce unwanted ambient sounds. ANC works when, it listens to the sound pattern outside and inside the earbud and after generates a mirror signal to cancel it out. In simple terms, it's like having +1 (noise) then adding -1 (counter sound by the device) to make zero hence "diluting" the noise.
Devialet Gemini have ANC allowing you to listen at lower volume levels, causing less ear fatigue since you don't need to crank up the device volume to overcome background noise.
Bang & Olufsen Beoplay EX too have Active Noise Cancellation making both earbuds ideal for flights and rush hour commutes. The Devialet Gemini and Bang & Olufsen Beoplay EX work with different noise cancellation settings, pick the mode that suits your travel or that suites your relaxation time.
Has Passive Noise Reduction

Bang & Olufsen Beoplay EX ✓
The Devialet Gemini stay tightly in place, this creates a sound covering that reduces your environment sounds well as preventing the device voice audio from leaking out at the same.
Both of these devices have passive noise reduction which implies that both reduce ambient noise without using ANC to cancel it out.
Driver Unit Size
Devialet Gemini
10mm
Bang & Olufsen Beoplay EX 9.2mm
The Devialet Gemini have a unit size of 10mm in diameter, the bigger the unit the more powerful, and can produce better bass.
The driver unit is the component that produces sound in the earbuds, its size corellates with the sound produced by the earbuds.
Bang & Olufsen Beoplay EX driver unit is 9.2mm in diameter,
which means that they have a smaller driver unit than that of Devialet Gemini by 0.8mm
, a common assumption 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 are capable of generating louder sound, but this does not imply that they produce better quality sound.
Lowest Frequency
Devialet Gemini
5Hz
Bang & Olufsen Beoplay EX 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 on its way through.
Bang & Olufsen Beoplay EX's lowest frequency is at 20Hz, this means that
Devialet Gemini make sound with a juicier bass than the Bang & Olufsen Beoplay EX
Highest Frequency
Devialet Gemini
20000Hz
Bang & Olufsen Beoplay EX 20000Hz
Devialet Gemini's highest frequency is at 20000Hz, high-frequency response measures if and how well an audio device generates high human frequencies and if it changes to the signal on its way through.
Bang & Olufsen Beoplay EX's highest frequency is at 20000Hz, this means that
both devices generate equal treble
Sound Pressure Level
Devialet Gemini
94dB/mW
Bang & Olufsen Beoplay EX ✗
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.
