Devialet Gemini 2 Vs. Bowers & Wilkins Pi7 Review In Detail

Design

Ingress Protection (Ip) Rating

Bowers & Wilkins PI7 IP54
Devialet Gemini 2 IPX4

Ingress protection ratings refer to the rank of protection given by an enclosure, against solids and water. The letters 'IP' are followed by two values The first value of the IP rating means protection against solids such as dust, followed by the one that refers to protection against liquids (water).

Having a value of IPX4, the Devialet Gemini 2's rating for solids indicates that no data available to specify a protection rating, and the second number of 4 means that they can withstand low pressure spray similar to that of a shower head when tilted at 180° for 10 minutes.

In comparison to the Devialet Gemini 2, Bowers & Wilkins PI7 have a rating of IP54 meaning that ingress of dust is not totally prevented but dust does not enter in harmful quantities to interfere with the correct operation or impair safety and that of liquids is that, they both have the same rating against liquids

Weight

Bowers & Wilkins PI7 50g
Devialet Gemini 2 12g

Devialet Gemini 2 have a weight of 12g . We consider a lower weight better because lighter devices are easier to transport.

The Bowers & Wilkins PI7, at 50g weigh more than the Devialet Gemini 2 with a difference of 38g

Has No Wires Or Cables

Bowers & Wilkins PI7
Devialet Gemini 2

For a device to be true wireless it must have no wires linking any part of the device together, Devialet Gemini 2 are true wireless for this case since they have no wires. This is an important difference as some wireless earbuds have cables connecting the 2 earbuds together.

Bowers & Wilkins PI7 also is true wireless because it has no cables linking the two earbuds together.

Sweat Resistance

Bowers & Wilkins PI7
Devialet Gemini 2

Devialet Gemini 2 are resistant to sweat

Has Stereo Speakers

Bowers & Wilkins PI7
Devialet Gemini 2

Devialet Gemini 2 have stereo speakers, what this means is that Devialet Gemini 2's speakers deliver sound from separate channels on both left and right sides, creating a richer sound and a better listening experience.

The Bowers & Wilkins PI7 also have stereo speakers

Sound Quality

Has Active Noise Cancellation (Noise Control)

Bowers & Wilkins PI7
Devialet Gemini 2

Active noise cancellation makes use of advanced technology to reduce unwanted ambient sounds. How it works, it detects and analyzes the sound pattern of incoming noise and then generates a mirror signal to cancel it out. In simple terms, it's like taking +1 (sound from your surrounding) and adding -1 (inverted noise) to make zero hence "diluting" the noise.

Devialet Gemini 2 have ANC enabling you to listen at lower levels of volume, causing less ear fatigue since you don't need to crank up the device volume to overcome background sounds.

The Bowers & Wilkins PI7 too have ANC making either of the earbuds ideal for plane rides and morning travels. Each operate with different noise cancellation modes, pick the setting that you prefer for commute or that enhances your chill time.

Has Passive Noise Reduction

Bowers & Wilkins PI7
Devialet Gemini 2

The Devialet Gemini 2 stay tightly in place, this creates a sound seal that tones down your environment noise well as preventing the earbuds sound from leaking out .

Both of these devices have passive noise reduction which implies that both reduce ambient noise without using technology to cancel it out.

Driver Unit Size

Bowers & Wilkins PI7 9.2mm
Devialet Gemini 2 10mm

The Devialet Gemini 2 have a unit size of 10mm in diameter, the bigger the unit the more powerful, therefor producing better bass. A driver unit is basically a mini speaker that produces sound in the earbuds, 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 find it difficult to produce high frequencies so yeah, larger drivers are capable of generating louder sound, but this does not imply that they produce better quality sound.

Lowest Frequency

Bowers & Wilkins PI7 10Hz
Devialet Gemini 2 5Hz

The Devialet Gemini 2's lowest frequency is at 5Hz, low-frequency response measures if and how well an audio device produces low audible frequencies and if it makes any changes to the signal on its way through.

Bowers & Wilkins PI7's lowest frequency is at 10Hz, this means 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 measures if and how well a particular audio device makes high audible frequencies and if it makes any adjustments to the signal while at it.

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

Sound Pressure Level

Bowers & Wilkins PI7
Devialet Gemini 2 120dB/mW

SPL, is the pressure level 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.

Power

Battery Life

Bowers & Wilkins PI7 4.5hours
Devialet Gemini 2 5hours

The Devialet Gemini 2's battery life is 5 hours, these last less than 5 hours of listening which is considered average before recharge. A device's battery life is given by the manufacturer, and with longer battery life, you get to use it for longer and requires fewer chargings.

Bowers & Wilkins PI7's battery life is less than that of Devialet Gemini 2 by 0.5 hours . Each time you recharge your earbuds, they get a little less listening time. The effect is not noticeable at first, but over time, your wireless earbuds will no longer play for long like they used to.

Battery Life Of Charging Case

Bowers & Wilkins PI7 18hours
Devialet Gemini 2 17hours

The battery life of the charging case is given by the manufacturer, and Devialet Gemini 2's case is said to have a charge of 17 hours. A charging case with a longer battery life allows you to recharge your earbuds on the go multiple times before having to recharge the case itself.

Bowers & Wilkins PI7's charging case has a battery life of 18 hours, more than that of Devialet Gemini 2 by 1 hours

Charge Time

Bowers & Wilkins PI7 3hours
Devialet Gemini 2 1hours

It requires 1 hours to fully charge the Devialet Gemini 2's battery. It is highly adivsable to charge fully the battery before using the earbuds when they have been unused for long periods.
