Has Active Noise Cancellation (Noise Control)

✓
Sennheiser Momentum True Wireless 3 ✓
Active noise cancellation makes use of advanced technology to reduce ambient sounds. How it works, it studies 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 (counter sound by the device) to make zero hence "diluting" the noise.
Huawei FreeBuds 5i have ANC enabling you to listen at lower volume levels, good for your ears since you don't need 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 devices ideal for plane rides and rush hour commutes. The Huawei FreeBuds 5i and Sennheiser Momentum True Wireless 3 operate with different noise cancellation settings, pick the noise cancellation type that you prefer for commute or that suites your relaxation time.

Both of these devices have passive noise reduction which means that they tone down ambient noise instead of actively using technology to cancel it out.
Driver Unit Size
Huawei FreeBuds 5i
10mm
Sennheiser Momentum True Wireless 3 7mm
The Huawei FreeBuds 5i driver unit is 10mm in diameter, bigger drivers are more powerful, therefor producing better bass.
The driver unit is the component that produces sound in the device, the unit size corellates with the sound produced 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 Huawei FreeBuds 5i by 3mm
, many people have a misconception that driver units of a bigger size automatically produce better sound quality.
However, large drivers usually have difficulty producing high frequencies so yes, larger drivers can generate louder sound, but this does not mean that they produce better quality sound.
Lowest Frequency
Huawei FreeBuds 5i
20Hz
Sennheiser Momentum True Wireless 3 5Hz
Huawei FreeBuds 5i'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 while at it.
Sennheiser Momentum True Wireless 3's lowest frequency is at 5Hz, this means that
Sennheiser Momentum True Wireless 3 can make sound with a juicier bass than the Huawei FreeBuds 5i
Highest Frequency
Huawei FreeBuds 5i
40000Hz
Sennheiser Momentum True Wireless 3 21000Hz
Huawei FreeBuds 5i's highest frequency is at 40000Hz, high-frequency response indicates how well an audio component produces high human 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 means that
Huawei FreeBuds 5i can produce a clearer and crispier treble than the Sennheiser Momentum True Wireless 3
Sound Pressure Level
Huawei FreeBuds 5i
✗
Sennheiser Momentum True Wireless 3 107dB/mW
SPL, is the pressure level 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.
