Ingress protection ratings refer to the rating of protection offered by an enclosure, against dust and water. The letters 'IP' are followed by two values The first value represents protection against solids say dust, followed by the one that refers to resistance against liquids (sweat).
Scoring 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, Sennheiser Momentum 3 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

Bowers & Wilkins PI7 driver unit is 9.2mm in diameter, the bigger the unit the more powerful, and can produce better bass.
The driver unit is the component that produces sound in the device, its size corellates with the sound produced by the earbuds. Sennheiser Momentum 3 driver unit is 7mm in diameter,
which means that they have a smaller driver unit than that of Bowers & Wilkins PI7 by 2.2mm
, 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 can generate louder sound, but this does not imply that they deliver better quality sound.
Bowers & Wilkins PI7's lowest frequency is at 10Hz, low-frequency response measures if and how well a particular audio component generates low frequencies that can be heard, and if it alters the signal while at it. Sennheiser Momentum 3's lowest frequency is at 5Hz, this means that Sennheiser Momentum 3 can make sound with a juicier bass than the Bowers & Wilkins PI7 The Bowers & Wilkins PI7's highest frequency is at 20,000Hz, high-frequency response tells how well an audio component generates high human frequencies and if it changes to the signal on its way through. Sennheiser Momentum 3's highest frequency is at 21,000Hz, this means that Sennheiser Momentum 3 can generate a clearer and crispier treble than the Bowers & Wilkins PI7 Bowers & Wilkins PI7's battery life is 4.5 hours, these last less than 5 hours of listening which is considered average for a single charge.
A device's battery life is usually given by the manufacturer, and with more battery hours, you get to use it for longer and have to charge the device less often. Sennheiser Momentum 3's battery life is more than that of Bowers & Wilkins PI7 by 2.5 hours . Each time you recharge your device, they get a little less listening time. The effect is not noticeable at first, but over time, your wireless earbuds will have shorter listening time.
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.
