IP ratings refer to the rank of protection given by a casing, against solids and water. The letters 'IP' are followed by two values The first value of the IP rating represents protection against solids such as dust, while the second refers to protection against liquids (water).
Scoring IP54, the Bowers & Wilkins PI7's rating is read as, the first value 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 best because lighter devices are more comfortable to transport.
The Sony WF 1000XM4, at 7.1g weigh less than the Bowers & Wilkins PI7 with a difference -42.9g
For a device to be true wireless it must have no wires connecting any part of the device together, Bowers & Wilkins PI7 are true wireless for this case since they don't have wires. This is a key difference since wireless earbuds have cables connecting the 2 earbuds .

Both Sony WF 1000XM4 and Bowers & Wilkins PI7 have stereo speakers
Active noise cancellation uses advanced kind of tech to actively counter noise. How it works, it studies the sound pattern of incoming noise and generates a mirror signal to counter it. Simply put, it's like having +1 (sound from your surrounding) and producing -1 (inverted noise) to make zero thus "diluting" the noise.
The Bowers & Wilkins PI7 have Active Noise Cancellation enabling you to listen at lower volume levels, good for your ears as you don't need to crank up the device volume to overcome background noise.
Sony WF 1000XM4 too have ANC which makes either of the devices ideal for plane rides and morning travels. The Bowers & Wilkins PI7 and Sony WF 1000XM4 operate with different noise cancellation modes, pick the mode that you prefer for commute or that suites your relaxation time.
Bowers & Wilkins PI7 sit well in place, this creates an acoustic seal that tones down your environment sounds well as preventing the device sound from leaking out .
Both Sony WF 1000XM4, and Bowers & Wilkins PI7 have passive noise reduction this means that both tone down ambient noise instead of actively using ANC to cancel it out.
Bowers & Wilkins PI7 driver unit is 9.2mm in diameter, the bigger the unit the more powerful, therefor producing better bass.
The driver unit is basically a mini speaker that produces sound in the device, its size corellates with the sound made by the earbuds.
Sony WF 1000XM4 driver unit is 6mm in diameter, which means that they have a smaller driver unit than that of Bowers & Wilkins PI7 by 3.2mm , many people have a misconception 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 imply that they produce better quality sound.
The Bowers & Wilkins PI7's lowest frequency is at 10Hz, low-frequency response inidcates how well an audio component produces low audible frequencies and if it makes any changes to the signal on its way through.
Sony WF 1000XM4's lowest frequency is at 20Hz, this means 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 an audio component makes high audible frequencies and if it changes to the signal on its way through.
Sony WF 1000XM4's highest frequency is at 40000Hz, this implies that Sony WF 1000XM4 produce a clearer and crispier treble than the Bowers & Wilkins PI7
SPL, is the pressure level of sound, in decibels, dB, Sony WF 1000XM4's measurement is 105dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
The Sony WF 1000XM4 have neodymium magnets, if used in audio devices 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.
The Bowers & Wilkins PI7's battery life is 4.5 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 more battery hours, you get to use it for longer and have to charge the device less often.
Sony WF 1000XM4's battery life is more than that of Bowers & Wilkins PI7 by 3.5 hours . Every time you recharge your earbuds, they get a little less playing time. The effect is barely noticeable at first, but over time, your wireless earbuds will no longer play for long like they used to.
The battery life of the charging case is given by the manufacturer, and the Bowers & Wilkins PI7's case has a charge of 18 hours. A charging case with more battery hours enables you to recharge your earbuds on the go many times before recharging the case itself.
