Has Active Noise Cancellation (Noise Control)

Sony WF C500 ✗
Active noise cancellation uses advanced kind of tech to actively counter noise. How it works, it detects and analyzes the sound pattern of incoming noise and inverts the soundwaves to cancel it out. Simply put, it's like having +1 (noise) then adding -1 (inverted noise) giving zero therefore "diluting" the noise.
The Sony WF 1000XM4 have ANC enabling you to listen at lower volume levels, good for your ears as you don't have to crank up the device volume to outcompete background noise.
Has Passive Noise Reduction

Sony WF C500 ✓
The Sony WF C500 sit tightly in place, creating an acoustic covering that tones down your environment sounds while preventing the device music from leaking out .
Both of these devices have passive noise reduction this means that both reduce ambient noise instead of actively using ANC to cancel it out.
Driver Unit Size
Sony WF 1000XM4
6mm
Sony WF C500 5.8mm
The Sony WF C500 have a unit size of 5.8mm in diameter, the bigger the unit the more powerful, and can produce better bass.
A driver unit is basically a mini speaker that produces sound in the device, its size dictates the loudness of the earbuds.
Sony WF 1000XM4 driver unit is 6mm in diameter,
making them have a larger driver unit than that of Sony WF C500 by 0.2mm
, many people have a misconception that driver units of a bigger size automatically produce better sound quality.
However, large drivers find it difficult to produce high frequencies so it's true that, larger drivers are capable of generating louder sound, but this does not indicate that they produce better quality sound.
Lowest Frequency
Sony WF 1000XM4
20Hz
Sony WF C500 20Hz
Sony WF C500's lowest frequency is at 20Hz, low-frequency response measures if and how well an audio component produces low recognizable frequencies and if it alters the signal while at it.
Sony WF 1000XM4's lowest frequency is at 20Hz, this implies that
both devices can make sound with equal bass
Highest Frequency
Sony WF 1000XM4
40000Hz
Sony WF C500 20000Hz
Sony WF C500's highest frequency is at 20000Hz, high-frequency response shows how well a particular audio component generates high human frequencies and if it changes to the signal on its way through.
Sony WF 1000XM4's highest frequency is at 40000Hz, this implies that
Sony WF 1000XM4 can produce a clearer and crispier treble than the Sony WF C500
Sound Pressure Level
Sony WF 1000XM4
105dB/mW
Sony WF C500 ✗
SPL, is the pressure level of sound, in decibels, dB, Sony WF 1000XM4's measurement is 105dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
Has A Neodymium Magnet
Sony WF 1000XM4
✓
Sony WF C500 ✓
The Sony WF C500 have neodymium magnets, if used in audio devices produce a higher sensitivity and substantial sound output using less power to do so. They can help generate music at quite a high sound pressure level, using high magnetic flux.
Sony WF 1000XM4 have it too, devices with neodymium magnets are lighter and more powerful . It is also known that they produce more bass and clearer high notes.
