Has Active Noise Cancellation (Noise Control)

Bowers & Wilkins PI7 ✓

Devialet Gemini 2 ✓

ANC utilises advanced kind of tech to actively cancel noise. ANC works when, it listens to the sound pattern of incoming noise and then generates a mirror signal to counter it. In simple terms, it's like taking +1 (sound from your surrounding) then producing -1 (inverted noise) giving zero thus "diluting" the noise.

Devialet Gemini 2 have Active Noise Cancellation allowing you to listen at lower levels of volume, good for your ears since you don't have to crank up the earbuds volume to outcompete background noise.

Driver Unit Size

Bowers & Wilkins PI7 9.2mm

Devialet Gemini 2 10mm

Devialet Gemini 2 have a unit size of 10mm in diameter, bigger drivers are more powerful, therefor producing better bass. A driver unit is the component that makes sound in the device, its size dictates 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 , 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 are capable of generating louder sound, but this does not mean that they produce better quality sound.

Lowest Frequency

Bowers & Wilkins PI7 10Hz

Devialet Gemini 2 5Hz

Highest Frequency

Bowers & Wilkins PI7 20,000Hz

Devialet Gemini 2 20,000Hz

The Devialet Gemini 2's highest frequency is at 20,000Hz, high-frequency response shows how well a particular audio component makes high human frequencies and if it adjustments to the signal on its way through.

Bowers & Wilkins PI7's highest frequency is at 20,000Hz, this implies that both devices can produce equal treble

Sound Pressure Level

Bowers & Wilkins PI7 ✗

Devialet Gemini 2 120dB/mW

SPL, 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.
