ANC uses more advanced kind of tech to actively cancel noise. ANC works when, it studies the sound pattern outside and inside the earbud and inverts the soundwaves to counter it. In simple terms, it's like taking +1 (noise) and adding -1 (inverted noise) giving zero resulting in a reduced level of 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 have to crank up the earbuds volume to outcompete background sounds.
The Beats Fit Pro too have Active Noise Cancellation which makes both earbuds ideal for plane rides and rush hour travels. The Sennheiser Momentum True Wireless 4 and Beats Fit Pro work with different noise cancellation settings, pick the noise cancellation type that suits your travel or that enhances your relaxation time.

Lowest Frequency
Sennheiser Momentum True Wireless 4
5Hz
Beats Fit Pro 20Hz
The Sennheiser Momentum True Wireless 4's lowest frequency is at 5Hz, low-frequency response inidcates how well a particular audio component produces low audible frequencies and if it alters the signal while at it.
Beats Fit Pro's lowest frequency is at 20Hz, this implies that
Sennheiser Momentum True Wireless 4 can make sound with a juicier bass than the Beats Fit Pro
Highest Frequency
Sennheiser Momentum True Wireless 4
21,000Hz
Beats Fit Pro 20,000Hz
Sennheiser Momentum True Wireless 4's highest frequency is at 21,000Hz, high-frequency response tells how well an audio device makes high human frequencies and if it makes any changes to the signal on its way through.
Beats Fit Pro's highest frequency is at 20,000Hz, this implies that
Sennheiser Momentum True Wireless 4 can generate a clearer and crispier treble than the Beats Fit Pro
Sound Pressure Level
Sennheiser Momentum True Wireless 4
107dB/mW
Beats Fit Pro 101.3dB/mW
The sound pressure level, is the pressure level of sound, measured 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.
Beats Fit Pro's sound pressure level measurement is 101.3dB/mW. How loud something is can be taken differently by different persons, so we need to have a way of getting an objective measurement of sound level expressed in numerical terms.
