Active noise cancellation utilises advanced technology to actively cancel noise. ANC works when, it studies the sound pattern outside and inside the earbud and then generates a mirror signal to counter it. Simply put, it's like having +1 (sound from your surrounding) then producing -1 (counter sound by the device) to make 0 therefore "diluting" the noise.
The Sennheiser Momentum True Wireless 4 have ANC allowing you to listen at lower levels of volume, causing less ear fatigue since you don't need to crank up the device volume to outcompete background sounds.
Google Pixel Buds Pro too have Active Noise Cancellation which makes both devices ideal for flights and rush hour commutes. Each work with different noise cancellation settings, pick the setting that suits your commute or that suites your relaxation time.

A driver unit is the component that makes sound in the device, its size dictates the sound produced by the earbuds.
Google Pixel Buds Pro driver unit is 11mm in diameter,
making them have a larger driver unit than that of Sennheiser Momentum True Wireless 4 by 4mm
, 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 yeah, larger drivers can generate louder sound, but this does not imply that they deliver better quality sound.
Lowest Frequency
Sennheiser Momentum True Wireless 4

Sound Pressure Level
Sennheiser Momentum True Wireless 4
107dB/mW
Google Pixel Buds Pro 75dB/mW
SPL, is the pressure level of sound, in decibels, dB, Sennheiser Momentum True Wireless 4's measurement is 107dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
Google Pixel Buds Pro's sound pressure level measurement is 75dB/mW. How loud something is can be perceived differently by separate people, so we need to have the means to get a standard measurement of sound level expressed in numerical terms.
