ANC utilises advanced technology to actively counter noise. How it works, it listens to the sound pattern of incoming noise and after generates a mirror signal to cancel it out. Simply put, it's like taking +1 (noise) then producing -1 (inverted noise) giving 0 resulting in a reduced level of noise.
Samsung Galaxy Buds 2 Pro have Active Noise Cancellation enabling you to listen at lower levels of volume, causing less ear fatigue as you don't need to crank up the device volume to outcompete background sounds.
The Sennheiser Momentum True Wireless 3 too have ANC which makes either of the devices ideal for flights and morning commutes. Each work with different noise cancellation types, pick the mode that you prefer for travel or that suites your chill time.
Has Passive Noise Reduction

Samsung Galaxy Buds 2 Pro sit well in place, creating an acoustic covering that tones down background sounds and also prevents the earbuds sound from leaking out .
Both of these devices have passive noise reduction which means that they tone down ambient noise without using ANC to cancel it out.
Driver Unit Size
Samsung Galaxy Buds 2 Pro
10mm
Sennheiser Momentum True Wireless 3 7mm
Samsung Galaxy Buds 2 Pro have a unit size of 10mm in diameter, the bigger the unit the more powerful, and can produce better bass.
The driver unit is the component that makes sound in the device, the unit size dictates the sound made by the device.
Sennheiser Momentum True Wireless 3 driver unit is 7mm in diameter,
which means that they have a smaller driver unit than that of Samsung Galaxy Buds 2 Pro by 3mm
, 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 yes, larger drivers are capable of generating louder sound, but this does not indicate that they deliver better quality sound.
Lowest Frequency
Samsung Galaxy Buds 2 Pro
20Hz
Sennheiser Momentum True Wireless 3 5Hz
Samsung Galaxy Buds 2 Pro's lowest frequency is at 20Hz, low-frequency response inidcates how well a particular audio component generates 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 Samsung Galaxy Buds 2 Pro
Highest Frequency
Samsung Galaxy Buds 2 Pro
20000Hz
Sennheiser Momentum True Wireless 3 21000Hz
Samsung Galaxy Buds 2 Pro's highest frequency is at 20000Hz, high-frequency response shows how well a particular audio device generates high human frequencies and if it makes any changes to the signal while at it.
Sennheiser Momentum True Wireless 3's highest frequency is at 21000Hz, this implies that
Sennheiser Momentum True Wireless 3 produce a clearer and crispier treble than the Samsung Galaxy Buds 2 Pro
Sound Pressure Level
Samsung Galaxy Buds 2 Pro
25dB/mW
Sennheiser Momentum True Wireless 3 107dB/mW
SPL, is the pressure level of sound, measured in decibels, dB, Samsung Galaxy Buds 2 Pro's measurement is 25dB/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 considered differently by different persons, so we need to have the means to get an objective measurement of sound level expressed in numerical terms.
