Has Active Noise Cancellation (Noise Control)
Audio Technica ATH TWX9
✓
Sennheiser Momentum True Wireless 3 ✓
Active noise cancellation utilises more advanced kind of tech to reduce unwanted ambient sounds. ANC works when, it studies the sound pattern outside and inside the earbud and generates a mirror signal to cancel it out. In simple terms, it's like having +1 (noise) then producing -1 (counter sound by the device) to make zero which results in a reduced level of noise.
Audio Technica ATH TWX9 have ANC allowing you to listen at lower levels of volume, causing less ear fatigue as you don't have to crank up the earbuds volume to outcompete background noise.
Sennheiser Momentum True Wireless 3 too have Active Noise Cancellation making either of the devices ideal for flights and rush hour commutes. The Audio Technica ATH TWX9 and Sennheiser Momentum True Wireless 3 work with different noise cancellation settings, pick the mode that you prefer for travel or that enhances your relaxation time.
Has Passive Noise Reduction

Audio Technica ATH TWX9 sit tightly in place, creating an acoustic covering that tones down background sounds and also prevents the device sound from leaking out at the same.
Both Sennheiser Momentum True Wireless 3, and Audio Technica ATH TWX9 have passive noise reduction which means that both limit ambient noise instead of actively using ANC to cancel it out.
Driver Unit Size
Audio Technica ATH TWX9
5.8mm
Sennheiser Momentum True Wireless 3 7mm
Audio Technica ATH TWX9 driver unit is 5.8mm in diameter, bigger drivers are more powerful, and can produce better bass.
A driver unit is the component that makes sound in the earbuds, its size corellates with the sound produced by the earbuds.
Sennheiser Momentum True Wireless 3 driver unit is 7mm in diameter,
making them have a larger driver unit than that of Audio Technica ATH TWX9 by 1.2mm
, a common assumption 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 indicate that they deliver better quality sound.
Lowest Frequency
Audio Technica ATH TWX9
20Hz
Sennheiser Momentum True Wireless 3 5Hz
The Audio Technica ATH TWX9's lowest frequency is at 20Hz, low-frequency response inidcates how well a particular audio component 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 can make sound with a juicier bass than the Audio Technica ATH TWX9
Highest Frequency
Audio Technica ATH TWX9
40000Hz
Sennheiser Momentum True Wireless 3 21000Hz
Audio Technica ATH TWX9's highest frequency is at 40000Hz, high-frequency response tells how well a particular audio component generates high audible frequencies and if it changes to the signal on its way through.
Sennheiser Momentum True Wireless 3's highest frequency is at 21000Hz, this means that
Audio Technica ATH TWX9 produce a clearer and crispier treble than the Sennheiser Momentum True Wireless 3
Sound Pressure Level
Audio Technica ATH TWX9
102dB/mW
Sennheiser Momentum True Wireless 3 107dB/mW
The sound pressure level, is the pressure level of sound, measured in decibels, dB, Audio Technica ATH TWX9's measurement is 102dB/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, something is can be considered differently by separate people, so we need to have a way of getting a standard measurement of sound level expressed in numerical terms.
