Has Active Noise Cancellation (Noise Control)
Audio Technica ATH TWX9
✓
Huawei FreeBuds 5i ✓
Active noise cancellation uses more advanced kind of tech to reduce ambient sounds. ANC works when, it detects and analyzes the sound pattern outside and inside the earbud and then generates a mirror signal to cancel it out. In simple terms, it's like taking +1 (sound from your surrounding) then producing -1 (counter sound by the device) giving zero resulting in a reduced level of noise.
Huawei FreeBuds 5i have ANC enabling you to listen at lower volume levels, good for your ears since you don't need to crank up the device volume to outcompete background noise.
Audio Technica ATH TWX9 too have Active Noise Cancellation making either of the devices ideal for plane rides and morning travels. The Huawei FreeBuds 5i and Audio Technica ATH TWX9 operate with different noise cancellation modes, pick the noise cancellation type that suits your commute or that suites your relaxation time.

Driver Unit Size
Audio Technica ATH TWX9
5.8mm
Huawei FreeBuds 5i 10mm
Huawei FreeBuds 5i have a unit size of 10mm in diameter, bigger drivers are more powerful, and can produce better bass.
The driver unit is the component that produces sound in the device, its size corellates with the sound produced by the earbuds.
Audio Technica ATH TWX9 driver unit is 5.8mm in diameter,
which implies that they have a smaller driver unit than that of Huawei FreeBuds 5i 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 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
Huawei FreeBuds 5i 20Hz
Huawei FreeBuds 5i'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 on its way through.
Audio Technica ATH TWX9's lowest frequency is at 20Hz, this implies that
both devices can produce equal bass
Highest Frequency
Audio Technica ATH TWX9
40000Hz
Huawei FreeBuds 5i 40000Hz
The Huawei FreeBuds 5i's highest frequency is at 40000Hz, high-frequency response measures if and how well an audio device makes high recognizable frequencies and if it makes any adjustments to the signal on its way through.
Audio Technica ATH TWX9's highest frequency is at 40000Hz, this implies that
both devices produce equal treble
Sound Pressure Level
Audio Technica ATH TWX9
102dB/mW
Huawei FreeBuds 5i ✗
The sound pressure level, 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.
