Has Active Noise Cancellation (Noise Control)

Active noise cancellation uses more advanced kind of tech to reduce ambient sounds. How it works, it studies the sound pattern of incoming noise and after generates a mirror signal to counter it. In simple terms, it's like having +1 (sound from your surrounding) then producing -1 (inverted noise) to make zero thus "diluting" the noise.
The Anker Soundcore Liberty 3 Pro have Active Noise Cancellation enabling you to listen at lower levels of volume, causing less ear fatigue as you don't have to crank up the earbuds volume to overcome background noise.
Sennheiser Momentum True Wireless 3 too have Active Noise Cancellation which makes either of the earbuds ideal for flights and morning travels. Each work with different noise cancellation types, pick the noise cancellation type that suits your travel or that suites your relaxation time.
Has Passive Noise Reduction

Anker Soundcore Liberty 3 Pro stay well in place, creating an acoustic covering that reduces background noise and also prevents the earbuds music from leaking out at the same.
Both of these devices have passive noise reduction which implies that they tone down ambient noise instead of actively using technology to cancel it out.
Driver Unit Size
Anker Soundcore Liberty 3 Pro
10.6mm
Sennheiser Momentum True Wireless 3 7mm
The Anker Soundcore Liberty 3 Pro have a unit size of 10.6mm in diameter, the bigger the unit the more powerful, therefor producing better bass.
A driver unit is the component that makes sound in the earbuds, the unit size corellates with the loudness of 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 Anker Soundcore Liberty 3 Pro by 3.6mm
, 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 are capable of generating louder sound, but this does not mean that they produce better quality sound.
Lowest Frequency
Anker Soundcore Liberty 3 Pro
20Hz
Sennheiser Momentum True Wireless 3 5Hz
Anker Soundcore Liberty 3 Pro's lowest frequency is at 20Hz, low-frequency response measures if and how well an audio device produces low frequencies that can be heard, 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 produce a juicier bass than the Anker Soundcore Liberty 3 Pro
Highest Frequency
Anker Soundcore Liberty 3 Pro
40000Hz
Sennheiser Momentum True Wireless 3 21000Hz
Anker Soundcore Liberty 3 Pro's highest frequency is at 40000Hz, high-frequency response shows how well a particular audio device makes high audible frequencies and if it makes any changes to the signal on its way through.
Sennheiser Momentum True Wireless 3's highest frequency is at 21000Hz, this implies that
Anker Soundcore Liberty 3 Pro can generate a clearer and crispier treble than the Sennheiser Momentum True Wireless 3
Sound Pressure Level
Anker Soundcore Liberty 3 Pro
92dB/mW
Sennheiser Momentum True Wireless 3 107dB/mW
SPL, is the level of pressure of sound, in decibels, dB, Anker Soundcore Liberty 3 Pro's measurement is 92dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
Sennheiser Momentum True Wireless 3's sound pressure level measurement is 107dB/mW. The sound pressure level, a device is can be perceived differently by separate people, so we need to have the means to get an objective measurement of sound level expressed in numerical terms.
