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

Design

Ingress Protection (Ip) Rating

Bowers & Wilkins PI7 IP54
Devialet Gemini 2 IPX4

IP ratings is the level of protection offered by an enclosure, against solids and water. The letters 'IP' are followed by two values The first value of the IP rating refers to protection against solids such as dust, followed by the one that refers to resistance against liquids (sweat).

Scoring IPX4, the Devialet Gemini 2's rating is read as, the first number of X denotes that no data available to specify a protection rating, and of liquids 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 prefer a lower weight better because lighter devices are easier to carry.

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

Has No Wires Or Cables

Bowers & Wilkins PI7
Devialet Gemini 2

True wireless devices have no wires connecting any part of the device together, Devialet Gemini 2 are true wireless for this matter since they don't have cables. This is an important difference as some wireless earbuds have cables connecting the two earbuds .

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

Sound Quality

Has Active Noise Cancellation (Noise Control)

Bowers & Wilkins PI7
Devialet Gemini 2

Active noise cancellation utilises more advanced technology to reduce ambient sounds. How it works, it studies the sound pattern outside and inside the earbud and then inverts the soundwaves to cancel it out. In simple terms, it's like taking +1 (noise) then producing -1 (counter sound by the device) to make zero resulting in a reduced level of noise.

The Devialet Gemini 2 have Active Noise Cancellation enabling you to listen at lower levels of volume, causing less ear fatigue as you don't need to crank up the earbuds volume to outcompete background sounds.

The Bowers & Wilkins PI7 too have ANC which makes either of the devices ideal for flights and morning travels. Each operate with different noise cancellation settings, pick the mode that you prefer for travel or that enhances your relaxation time.

Has Passive Noise Reduction

Bowers & Wilkins PI7
Devialet Gemini 2

The Devialet Gemini 2 sit tightly in place, creating a sound seal that tones down your environment sounds while preventing the earbuds music from leaking out at the same.

Both of these devices have passive noise reduction which means that they 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 driver unit is 10mm in diameter, the bigger the unit the more powerful, and can produce better bass. A driver unit is the component that makes sound in the earbuds, its size corellates with the sound produced by the earbuds.

Bowers & Wilkins PI7 driver unit is 9.2mm in diameter, which means 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 mean that they deliver 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 inidcates how well an audio component generates low audible frequencies and if it alters the signal while at it.

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 generates high recognizable frequencies and if it makes any changes to the signal while at it.

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
