IP ratings is the level of protection offered by an enclosure, against dust and water. In the format of IPXX, 'X' represents a number The first value of the IP rating means protection against solids say dust, while the second refers to protection against liquids (sweat).
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 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 Bowers & Wilkins PI7, Sennheiser Momentum True Wireless 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
The Bowers & Wilkins PI7 have a weight of 50g . We take in account a lower weight better because lighter devices are more comfortable to carry.
The Sennheiser Momentum True Wireless 3, at 10.6g
are lighter than the Bowers & Wilkins PI7 with a difference -39.4g
True wireless devices have no wires linking any part of the device together, Bowers & Wilkins PI7 are true wireless for this matter since they don't have wires. This is an important difference since wireless earbuds have cables linking the 2 earbuds together. Sennheiser Momentum True Wireless 3 also is true wireless because it doesn't have wires linking the pair of earbuds .
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 Sennheiser Momentum True Wireless 3 also have stereo speakers
Active noise cancellation uses advanced kind of tech to reduce ambient sounds. ANC works when, it studies the sound pattern outside and inside the earbud and then inverts the soundwaves to cancel it out. Simply put, it's like taking +1 (sound from your surrounding) then adding -1 (counter sound by the device) giving zero resulting in a reduced level of noise.
Bowers & Wilkins PI7 have ANC enabling you to listen at lower volume levels, causing less ear fatigue since you don't have to crank up the device volume to outcompete background sounds. The Sennheiser Momentum True Wireless 3 too have ANC making both devices ideal for plane rides and rush hour travels. Each work with different noise cancellation settings, pick the setting that you prefer for travel or that suites your chill time.
The Bowers & Wilkins PI7 stay well in place, this creates a sound seal that reduces your environment noise while preventing the earbuds music from leaking out .
Both Sennheiser Momentum True Wireless 3, and Bowers & Wilkins PI7 have passive noise reduction which means that they reduce ambient noise without using technology to cancel it out. 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 makes sound in the earbuds, the unit size dictates the sound made by the device.
Sennheiser Momentum True Wireless 3 driver unit is 7mm in diameter,
which implies 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 find it difficult to produce high frequencies so it's true that, 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 measures if and how well a particular audio component produces low audible frequencies and if it alters the signal on its way through.
Sennheiser Momentum True Wireless 3's lowest frequency is at 5Hz, this implies that
Sennheiser Momentum True Wireless 3 can produce a juicier bass than the Bowers & Wilkins PI7
Bowers & Wilkins PI7's highest frequency is at 20,000Hz, high-frequency response indicates how well a particular audio component generates high audible frequencies and if it changes to the signal while at it. Sennheiser Momentum True Wireless 3's highest frequency is at 21,000Hz, this means that
Sennheiser Momentum True Wireless 3 can generate a clearer and crispier treble than the Bowers & Wilkins PI7
The 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 longer battery life, you get to use it for longer and requires fewer chargings.
Sennheiser Momentum True Wireless 3's battery life is
more than that of Bowers & Wilkins PI7 by 2.5 hours
. Every time you recharge your device, they get a little less playing time. The effect is barely noticeable at first, but over a few years, 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 Bowers & Wilkins PI7's case has a full charge of 18 hours.
A charging case with more battery hours enables you to recharge your earbuds on the go many times before having to recharge the case itself. Sennheiser Momentum True Wireless 3's charging case has a battery life of 21 hours,
more than that of Bowers & Wilkins PI7 by 3 hours
It takes 3 hours to fully charge the Bowers & Wilkins PI7's battery. It is highly adivsable to fully charge the battery before using the earbuds for the first time.
Sennheiser Momentum True Wireless 3 takes 1.5 hours to fully charge the battery,
less than that of Bowers & Wilkins PI7 by 1.5 hours
