Has Active Noise Cancellation (Noise Control)
Audio Technica ATH TWX9
✓
Sony WF C500 ✗
ANC uses more advanced kind of tech to actively cancel noise. How it works, it listens to the sound pattern outside and inside the earbud and after inverts the soundwaves to cancel it out. In simple terms, it's like taking +1 (sound from your surrounding) then producing -1 (inverted noise) to make 0 thus "diluting" the noise.
Audio Technica ATH TWX9 have ANC allowing you to listen at lower levels of volume, causing less ear fatigue as you don't need to crank up the device volume to outcompete background noise.
Has Passive Noise Reduction

Sony WF C500 ✓
Audio Technica ATH TWX9 sit well in place, this creates a sound seal that reduces your environment noise and also prevents the device music from leaking out at the same.
Both Sony WF C500, and Audio Technica ATH TWX9 have passive noise reduction this means that they limit ambient noise instead of actively using ANC to cancel it out.
Driver Unit Size
Audio Technica ATH TWX9
5.8mm
Sony WF C500 5.8mm
The Audio Technica ATH TWX9 have a unit size of 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 device.
Sony WF C500 driver unit is 5.8mm in diameter,
making both Sony WF C500, and Audio Technica ATH TWX9 similar in how loud their sound gets
, 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 it's true that, larger drivers can generate louder sound, but this does not indicate that they produce better quality sound.
Lowest Frequency
Audio Technica ATH TWX9
20Hz
Sony WF C500 20Hz
The Audio Technica ATH TWX9's lowest frequency is at 20Hz, low-frequency response measures if and how well a particular audio component produces low frequencies that can be heard, and if it makes any changes to the signal on its way through.
Sony WF C500's lowest frequency is at 20Hz, this implies that
both devices can produce equal bass
Highest Frequency
Audio Technica ATH TWX9
40000Hz
Sony WF C500 20000Hz
The Audio Technica ATH TWX9's highest frequency is at 40000Hz, high-frequency response measures if and how well a particular audio component produces high human frequencies and if it adjustments to the signal on its way through.
Sony WF C500's highest frequency is at 20000Hz, this means that
Audio Technica ATH TWX9 generate a clearer and crispier treble than the Sony WF C500
Sound Pressure Level
Audio Technica ATH TWX9
102dB/mW
Sony WF C500 ✗
The sound pressure level, is the level of pressure of sound, 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.
Has A Neodymium Magnet
Audio Technica ATH TWX9
✗
Sony WF C500 ✓
Sony WF C500 have neodymium magnets, when used in earbuds produce a higher sensitivity and substantial sound output using less power to do so. They can help produce music at quite a high SPL, with the use of high magnetic flux.
