Has Active Noise Cancellation (Noise Control)
Audio Technica ATH TWX9
✓
Sony WF C500 ✗
Active noise cancellation utilises advanced technology to actively cancel noise. How it works, it listens to the sound pattern of incoming noise and after generates a mirror signal to counter it. Simply put, it's like taking +1 (sound from your surrounding) then producing -1 (counter sound by the device) giving 0 resulting in a reduced level of noise.
The Audio Technica ATH TWX9 have Active Noise Cancellation enabling you to listen at lower volume levels, 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 ✓
Audio Technica ATH TWX9 stay well 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 Sony WF C500, and Audio Technica ATH TWX9 have passive noise reduction this implies that both limit ambient noise without using ANC to cancel it out.
Driver Unit Size
Audio Technica ATH TWX9
5.8mm
Sony WF C500 5.8mm
Audio Technica ATH TWX9 driver unit is 5.8mm in diameter, the bigger the unit the more powerful, therefor producing better bass.
The driver unit is basically a mini speaker that produces sound in the device, the unit size dictates the loudness of 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 can get
, as many tend to believe 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 mean that they deliver 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 an audio device generates low frequencies that can be heard, and if it alters the signal on its way through.
Sony WF C500's lowest frequency is at 20Hz, this implies that
both devices can make sound with 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 tells how well a particular audio device generates high audible frequencies and if it makes any adjustments to the signal while at it.
Sony WF C500's highest frequency is at 20000Hz, this means that
Audio Technica ATH TWX9 can generate a clearer and crispier treble than the Sony WF C500
Sound Pressure Level
Audio Technica ATH TWX9
102dB/mW
Sony WF C500 ✗
SPL, 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.
Has A Neodymium Magnet
Audio Technica ATH TWX9
✗
Sony WF C500 ✓
The Sony WF C500 have neodymium magnets, when used in audio devices produce a higher sensitivity and substantial sound output while using less power. They can help produce music at quite a high sound pressure level, using high magnetic flux.
