Ingress protection ratings is the rating of protection given by a casing, against solids and water. In the format of IPXX, 'X' represents a number The first value of the IP rating represents protection against solids such as dust, followed by the one that refers to resistance against liquids (water).
Having a value of IP54, the Bowers & Wilkins PI7's rating is read as, the first number of 5 denotes 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 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 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
The Bowers & Wilkins PI7 have a weight of 50g . We take in account a lower weight better for the reason that lighter devices are easier to transport.
Sony WF 1000XM4, at 41g weigh less than the Bowers & Wilkins PI7 with a difference -9g
True wireless devices have no cables linking any part of the device together, Bowers & Wilkins PI7 are true wireless for this matter since they don't have cables. This is an important difference as some wireless earbuds have cables linking the 2 earbuds together.
Sony WF 1000XM4 also is true wireless because it has no cables connecting the two earbuds .
Sony WF 1000XM4 have sweat resistance
Bowers & Wilkins PI7 have stereo speakers, what this means is that Bowers & Wilkins PI7's speakers deliver sound from independent channels on both left and right sides, this creates a richer sound and a better listening experience.
The Sony WF 1000XM4 also have stereo speakers
Active noise cancellation makes use of advanced technology to reduce ambient sounds. How it works, it studies 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 producing -1 (inverted noise) to make 0 resulting in a reduced level of noise.
Bowers & Wilkins PI7 have ANC allowing you to listen at lower volume levels, good for your ears since you don't need to crank up the earbuds volume to outcompete background noise.
The Sony WF 1000XM4 too have Active Noise Cancellation making both earbuds ideal for flights and rush hour travels. The Bowers & Wilkins PI7 and Sony WF 1000XM4 work with different noise cancellation settings, pick the mode that suits your travel or that suites your relaxation time.
Bowers & Wilkins PI7 sit well in place, creating an acoustic seal that reduces background noise well as preventing the device voice audio from leaking out at the same.
Both of these devices have passive noise reduction this means that both reduce ambient noise instead of actively using technology to cancel it out.
The Bowers & Wilkins PI7 driver unit is 9.2mm in diameter, bigger drivers are more powerful, therefor producing better bass.
The driver unit is the component that produces sound in the earbuds, its size corellates with the loudness of the device.
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 usually have difficulty producing high frequencies so yeah, larger drivers can generate louder sound, but this does not mean that they produce better quality sound.
The Bowers & Wilkins PI7's lowest frequency is at 10Hz, low-frequency response inidcates how well a particular audio component produces low recognizable frequencies and if it alters the signal while at it.
Sony WF 1000XM4's lowest frequency is at 20Hz, this implies that Bowers & Wilkins PI7 produce a juicier bass than the Sony WF 1000XM4
The Bowers & Wilkins PI7's highest frequency is at 20000Hz, high-frequency response indicates how well a particular audio component generates high audible frequencies and if it adjustments to the signal while at it.
Sony WF 1000XM4's highest frequency is at 40000Hz, this implies that Sony WF 1000XM4 can generate a clearer and crispier treble than the Bowers & Wilkins PI7
The Sony WF 1000XM4 have neodymium magnets, if used in earbuds produce a higher sensitivity and substantial sound output while using less power. They can help generate music at quite a high sound pressure level, with the use of high magnetic flux.
Bowers & Wilkins PI7's battery life is 4.5 hours, a device's battery life is given by the manufacturer, and with more battery hours, you get to use it for longer and requires fewer chanrgings.
Sony WF 1000XM4's battery life is more than that of Bowers & Wilkins PI7 by 3.5 hours . Every time you recharge your device, they get a little less listening time. The effect is not noticeable at first, but over a few years, your wireless earbuds will no longer play for long like they used to.
This is given by the manufacturer, and Bowers & Wilkins PI7's case is said to have a full charge of 18 hours. A charging case with a longer battery life allows you to recharge your earbuds on the go many times before having to recharge the case itself.
Sony WF 1000XM4's charging case has a battery life of 16 hours, less than that of Bowers & Wilkins PI7 by 2 hours
It requires 3 hours to fully charge the Bowers & Wilkins PI7's battery. It is recommended to fully charge the battery before using the earbuds when they have been in storage for extended periods.
Sony WF 1000XM4 takes 1.5 hours to fully charge the battery, less than that of Bowers & Wilkins PI7 by 1.5 hours
