Sony WF C500 ✗
ANC uses advanced kind of tech to actively counter noise. ANC works when, it detects and analyzes the sound pattern outside and inside the earbud and after generates a mirror signal to cancel it out. Simply put, it's like taking +1 (sound from your surrounding) then adding -1 (inverted noise) to make zero resulting in a reduced level of noise.
Sennheiser Momentum True Wireless 3 have Active Noise Cancellation allowing you to listen at lower levels of volume, causing less ear fatigue since you don't have to crank up the device volume to overcome background noise.
Has Passive Noise Reduction

Sony WF C500 ✓
The Sony WF C500 stay tightly in place, creating a sound covering that tones down your environment noise and also prevents the device voice audio from leaking out at the same.
Both of these devices have passive noise reduction which means that both limit ambient noise instead of actively using technology to cancel it out.
Driver Unit Size
Sennheiser Momentum True Wireless 3
7mm
Sony WF C500 5.8mm
Sony WF C500 have a unit size of 5.8mm in diameter, bigger drivers are more powerful, therefor producing better bass.
A driver unit is the component that produces sound in the earbuds, the unit size dictates the loudness of the earbuds.
Sennheiser Momentum True Wireless 3 driver unit is 7mm in diameter,
making them have a larger driver unit than that of Sony WF C500 by 1.2mm
, 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 can generate louder sound, but this does not imply that they deliver better quality sound.
Lowest Frequency
Sennheiser Momentum True Wireless 3
5Hz
Sony WF C500 20Hz
Sony WF C500's lowest frequency is at 20Hz, low-frequency response inidcates how well an audio device generates low frequencies that can be heard, and if it makes any changes to the signal on its way through.
Sennheiser Momentum True Wireless 3's lowest frequency is at 5Hz, this means that
Sennheiser Momentum True Wireless 3 make sound with a juicier bass than the Sony WF C500
Highest Frequency
Sennheiser Momentum True Wireless 3
21000Hz
Sony WF C500 20000Hz
The Sony WF C500's highest frequency is at 20000Hz, high-frequency response measures if and how well a particular audio device produces high human frequencies and if it adjustments to the signal on its way through.
Sennheiser Momentum True Wireless 3's highest frequency is at 21000Hz, this means that
Sennheiser Momentum True Wireless 3 generate a clearer and crispier treble than the Sony WF C500
Sound Pressure Level
Sennheiser Momentum True Wireless 3
107dB/mW
Sony WF C500 ✗
The sound pressure level, is the level of pressure 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.
Has A Neodymium Magnet

Sony WF C500 ✓
Sony WF C500 have neodymium magnets, if used in earbuds produce a higher sensitivity and substantial sound output while using less power. They can help produce music at quite a high SPL, with the use of high magnetic flux.
