Sennheiser Momentum True Wireless 3 ✓
Active noise cancellation makes use of advanced kind of tech to reduce ambient sounds. ANC works when, it listens to the sound pattern of incoming noise and generates a mirror signal to cancel it out. Simply put, it's like having +1 (sound from your surrounding) and producing -1 (counter sound by the device) to make zero resulting in a reduced level of noise.
The Bowers & Wilkins PI7 have Active Noise Cancellation enabling you to listen at lower levels of volume, good for your ears since you don't have to crank up the device volume to overcome background sounds.
The Sennheiser Momentum True Wireless 3 too have Active Noise Cancellation making either of the earbuds ideal for flights and morning commutes. The Bowers & Wilkins PI7 and Sennheiser Momentum True Wireless 3 work with different noise cancellation settings, pick the noise cancellation type that suits your travel or that enhances your chill time.

Sennheiser Momentum True Wireless 3 ✓
The Bowers & Wilkins PI7 sit well in place, creating a sound seal that tones down background noise well as preventing the device music from leaking out .
Both Sennheiser Momentum True Wireless 3, and Bowers & Wilkins PI7 have passive noise reduction which implies that both tone down ambient noise instead of actively using ANC to cancel it out.
Driver Unit Size
Bowers & Wilkins PI7
9.2mm
Sennheiser Momentum True Wireless 3 7mm
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 the component that produces sound in the device, the unit size dictates the sound made by the earbuds.
Sennheiser Momentum True Wireless 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
, a common assumption that driver units of a bigger size automatically produce better sound quality.
However, large drivers find it difficult to produce high frequencies so yeah, larger drivers can generate louder sound, but this does not mean that they produce better quality sound.
Lowest Frequency
Bowers & Wilkins PI7
10Hz
Sennheiser Momentum True Wireless 3 5Hz
Bowers & Wilkins PI7's lowest frequency is at 10Hz, low-frequency response measures if and how well an audio device generates low frequencies that can be heard, and if it makes any changes to the signal while at it.
Sennheiser Momentum True Wireless 3's lowest frequency is at 5Hz, this means that
Sennheiser Momentum True Wireless 3 make sound with a juicier bass than the Bowers & Wilkins PI7
Highest Frequency
Bowers & Wilkins PI7
20000Hz
Sennheiser Momentum True Wireless 3 21000Hz
The Bowers & Wilkins PI7's highest frequency is at 20000Hz, high-frequency response tells how well an audio component produces high human frequencies and if it changes to the signal on its way through.
Sennheiser Momentum True Wireless 3's highest frequency is at 21000Hz, this implies that
Sennheiser Momentum True Wireless 3 can generate a clearer and crispier treble than the Bowers & Wilkins PI7
Sound Pressure Level
Bowers & Wilkins PI7
✗
Sennheiser Momentum True Wireless 3 107dB/mW
The sound pressure level, is the level of pressure of sound, in decibels, dB, Sennheiser Momentum True Wireless 3's measurement is 107dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
