Bowers & Wilkins Pi7 Vs. Sony Wf 1000Xm4 Review In Detail

Design

Ingress Protection (Ip) Rating

Sony WF 1000XM4 IPX4
Bowers & Wilkins PI7 IP54

Ingress protection ratings is the rank of protection given by an enclosure, against solids and liquids. The letters 'IP' are followed by two values The first value represents protection against solids say dust, while the second refers to resistance against liquids (sweat).

Having a value of IP54, the Bowers & Wilkins PI7's rating for solids indicates 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 the second value 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 Bowers & Wilkins PI7, Sony WF 1000XM4 have a rating of IPX4 meaning that no data available to specify a protection rating and that of liquids is that, they both have the same rating against liquids

Sound Quality

Has Active Noise Cancellation (Noise Control)

Sony WF 1000XM4
Bowers & Wilkins PI7

Active noise cancellation uses advanced technology to actively counter noise. How it works, it studies the sound pattern outside and inside the earbud and after generates a mirror signal to counter it. Simply put, it's like taking +1 (noise) then adding -1 (counter sound by the device) to make zero therefore "diluting" the noise.

The Bowers & Wilkins PI7 have ANC enabling you to listen at lower volume levels, causing less ear fatigue as you don't need to crank up the device volume to outcompete background sounds.

The Sony WF 1000XM4 too have Active Noise Cancellation making either of the devices ideal for plane rides and rush hour commutes. The Bowers & Wilkins PI7 and Sony WF 1000XM4 operate with different noise cancellation types, pick the noise cancellation type that you prefer for travel or that enhances your relaxation time.

Has Passive Noise Reduction

Sony WF 1000XM4
Bowers & Wilkins PI7

Bowers & Wilkins PI7 stay well in place, creating an acoustic covering that tones down your environment sounds well as preventing the device sound from leaking out .

Both of these devices have passive noise reduction this means that they tone down ambient noise instead of actively using ANC to cancel it out.

Driver Unit Size

Sony WF 1000XM4 6mm
Bowers & Wilkins PI7 9.2mm

The Bowers & Wilkins PI7 have a unit size of 9.2mm in diameter, bigger drivers are more powerful, and can produce better bass. A driver unit is the component that makes sound in the earbuds, the unit size determines the loudness of the earbuds.

Sony WF 1000XM4 driver unit is 6mm in diameter, which implies that they have a smaller driver unit than that of Bowers & Wilkins PI7 by 3.2mm , 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 it's true that, larger drivers are capable of generating louder sound, but this does not mean that they deliver better quality sound.

Lowest Frequency

Sony WF 1000XM4 20Hz
Bowers & Wilkins PI7 10Hz
