Has Active Noise Cancellation (Noise Control)
Google Pixel Buds Pro
✓
Devialet Gemini 2 ✓
Active noise cancellation utilises advanced technology to actively counter noise. ANC works when, it listens to the sound pattern of incoming noise and then inverts the soundwaves to counter it. Simply put, it's like taking +1 (sound from your surrounding) then adding -1 (counter sound by the device) to make 0 hence "diluting" the noise.
Devialet Gemini 2 have Active Noise Cancellation enabling you to listen at lower volume levels, good for your ears as you don't need to crank up the earbuds volume to outcompete background noise.
Google Pixel Buds Pro too have ANC making either of the earbuds ideal for flights and morning travels. Each work with different noise cancellation modes, pick the mode that suits your travel or that enhances your relaxation time.
Has Passive Noise Reduction

Devialet Gemini 2 ✓
Devialet Gemini 2 sit tightly in place, this creates a sound seal that reduces background sounds and also prevents the device sound from leaking out at the same.
Both Google Pixel Buds Pro, and Devialet Gemini 2 have passive noise reduction this means that they limit ambient noise without using ANC to cancel it out.
Driver Unit Size
Google Pixel Buds Pro
11mm
Devialet Gemini 2 10mm
The Devialet Gemini 2 driver unit is 10mm in diameter, bigger drivers are more powerful, and can produce better bass.
The driver unit is the component that produces sound in the earbuds, its size corellates with the loudness of the earbuds.
Google Pixel Buds Pro driver unit is 11mm in diameter,
making them have a larger driver unit than that of Devialet Gemini 2 by 1mm
, 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 it's true that, larger drivers are capable of generating louder sound, but this does not indicate that they produce better quality sound.
Lowest Frequency
Google Pixel Buds Pro
20Hz
Devialet Gemini 2 5Hz
Devialet Gemini 2's lowest frequency is at 5Hz, low-frequency response measures if and how well a particular audio component generates low audible frequencies and if it alters the signal on its way through.
Google Pixel Buds Pro's lowest frequency is at 20Hz, this means that
Devialet Gemini 2 can produce a juicier bass than the Google Pixel Buds Pro
Highest Frequency
Google Pixel Buds Pro
20,000Hz
Devialet Gemini 2 20,000Hz
The Devialet Gemini 2's highest frequency is at 20,000Hz, high-frequency response shows how well an audio device generates high recognizable frequencies and if it makes any adjustments to the signal on its way through.
Google Pixel Buds Pro's highest frequency is at 20,000Hz, this means that
both devices can generate equal treble
Sound Pressure Level
Google Pixel Buds Pro
75dB/mW
Devialet Gemini 2 120dB/mW
The sound pressure level, is the level of pressure of sound, measured in decibels, dB, Devialet Gemini 2's measurement is 120dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
Google Pixel Buds Pro's sound pressure level measurement is 75dB/mW. How loud a device is can be taken differently by different people, so we need to have the means to get a standard measurement of sound level expressed in numerical terms.
