Has Active Noise Cancellation (Noise Control)

Devialet Gemini 2 ✓
Active noise cancellation makes use of more advanced kind of tech to reduce unwanted ambient sounds. How it works, it listens to the sound pattern of incoming noise and after inverts the soundwaves to cancel it out. Simply put, it's like taking +1 (sound from your surrounding) and adding -1 (counter sound by the device) to make 0 hence "diluting" the noise.
Devialet Gemini 2 have Active Noise Cancellation allowing 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 sounds.
Bowers & Wilkins PI7 too have ANC making either of the earbuds ideal for flights and morning travels. The Devialet Gemini 2 and Bowers & Wilkins PI7 operate with different noise cancellation modes, pick the setting that suits your commute or that suites your relaxation time.
Has Passive Noise Reduction

Devialet Gemini 2 ✓
Devialet Gemini 2 stay well in place, this creates a sound covering that reduces background sounds and also prevents the earbuds music from leaking out at the same.
Both of these devices have passive noise reduction which means that they tone down ambient noise instead of actively using technology to cancel it out.
Driver Unit Size
Bowers & Wilkins PI7
9.2mm
Devialet Gemini 2 10mm
Devialet Gemini 2 driver unit is 10mm in diameter, bigger drivers are more powerful, and can produce better bass.
The driver unit is basically a mini speaker that produces sound in the device, the unit size determines the loudness of the earbuds.
Bowers & Wilkins PI7 driver unit is 9.2mm in diameter,
which implies that they have a smaller driver unit than that of Devialet Gemini 2 by 0.8mm
, a common assumption 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 are capable of generating louder sound, but this does not indicate that they deliver better quality sound.
Lowest Frequency
Bowers & Wilkins PI7
10Hz
Devialet Gemini 2 5Hz
Devialet Gemini 2's lowest frequency is at 5Hz, low-frequency response inidcates how well a particular audio device produces low frequencies that can be heard, and if it makes any changes to the signal on its way through.
Bowers & Wilkins PI7's lowest frequency is at 10Hz, this implies that
Devialet Gemini 2 produce a juicier bass than the Bowers & Wilkins PI7
Highest Frequency
Bowers & Wilkins PI7
20,000Hz
Devialet Gemini 2 20,000Hz
Devialet Gemini 2's highest frequency is at 20,000Hz, high-frequency response indicates how well an audio component generates high recognizable frequencies and if it changes to the signal while at it.
Bowers & Wilkins PI7's highest frequency is at 20,000Hz, this means that
both devices can generate equal treble
Sound Pressure Level
Bowers & Wilkins PI7
✗
Devialet Gemini 2 120dB/mW
The sound pressure level, is the level of pressure of sound, 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.
