ANC makes use of advanced kind of tech to reduce ambient sounds. ANC works when, it detects and analyzes the sound pattern of incoming noise and after generates a mirror signal to counter it. In simple terms, it's like taking +1 (sound from your surrounding) and adding -1 (inverted noise) giving zero therefore "diluting" the noise.
The Razer Hammerhead True Wireless Earbuds (2nd Gen) have Active Noise Cancellation enabling you to listen at lower volume levels, good for your ears as you don't need to crank up the earbuds volume to outcompete background noise.

The Razer Hammerhead True Wireless Earbuds (2nd Gen) sit tightly in place, this creates an acoustic seal that tones down background noise while preventing the earbuds sound from leaking out .
Both Sony WF C500, and Razer Hammerhead True Wireless Earbuds (2nd Gen) have passive noise reduction this implies that both tone down ambient noise instead of actively using ANC to cancel it out.
Driver Unit Size
Razer Hammerhead True Wireless Earbuds (2nd Gen)
10mm
Sony WF C500 5.8mm
Razer Hammerhead True Wireless Earbuds (2nd Gen) have a unit size of 10mm in diameter, bigger drivers are more powerful, therefor producing better bass.
A driver unit is the component that makes sound in the earbuds, its size corellates with the sound produced by the earbuds.
Sony WF C500 driver unit is 5.8mm in diameter,
which implies that they have a smaller driver unit than that of Razer Hammerhead True Wireless Earbuds (2nd Gen) by 4.2mm
, 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 are capable of generating louder sound, but this does not indicate that they deliver better quality sound.
Lowest Frequency
Razer Hammerhead True Wireless Earbuds (2nd Gen)
20hz
Sony WF C500 20hz
The Razer Hammerhead True Wireless Earbuds (2nd Gen)'s lowest frequency is at 20Hz, low-frequency response measures if and how well an audio device produces low audible frequencies and if it makes any changes to the signal while at it.
Sony WF C500's lowest frequency is at 20Hz, this means that
both devices can make sound with equal bass
Highest Frequency
Razer Hammerhead True Wireless Earbuds (2nd Gen)
20,000hz
Sony WF C500 20,000hz
Razer Hammerhead True Wireless Earbuds (2nd Gen)'s highest frequency is at 20,000Hz, high-frequency response tells how well an audio device produces high human frequencies and if it adjustments to the signal while at it.
Sony WF C500's highest frequency is at 20,000Hz, this implies that
both devices can produce equal treble
