Has Active Noise Cancellation (Noise Control)

Active noise cancellation utilises advanced technology to actively cancel noise. ANC works when, it studies the sound pattern of incoming noise and after inverts the soundwaves to cancel it out. In simple terms, it's like taking +1 (sound from your surrounding) and adding -1 (counter sound by the device) giving 0 which results in a reduced level of noise.
The OnePlus Buds Pro 2 have Active Noise Cancellation allowing you to listen at lower levels of volume, good for your ears since you don't need to crank up the device volume to overcome background noise.
Audio Technica ATH TWX9 too have ANC which makes both earbuds ideal for plane rides and morning commutes. Each work with different noise cancellation types, pick the noise cancellation type that you prefer for commute or that suites your relaxation time.

Driver Unit Size
OnePlus Buds Pro 2
11mm
Audio Technica ATH TWX9 5.8mm
OnePlus Buds Pro 2 driver unit is 11mm in diameter, bigger drivers are more powerful, therefor producing better bass.
A driver unit is basically a mini speaker that makes sound in the device, its size corellates with the loudness of the earbuds.
Audio Technica ATH TWX9 driver unit is 5.8mm in diameter,
which means that they have a smaller driver unit than that of OnePlus Buds Pro 2 by 5.2mm
, 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 are capable of generating louder sound, but this does not indicate that they deliver better quality sound.
Lowest Frequency
OnePlus Buds Pro 2
10Hz
Audio Technica ATH TWX9 20Hz
OnePlus Buds Pro 2's lowest frequency is at 10Hz, low-frequency response measures if and how well a particular audio device produces low recognizable frequencies and if it alters the signal on its way through.
Audio Technica ATH TWX9's lowest frequency is at 20Hz, this implies that
OnePlus Buds Pro 2 produce a juicier bass than the Audio Technica ATH TWX9
Highest Frequency
OnePlus Buds Pro 2
40000Hz
Audio Technica ATH TWX9 40000Hz
The OnePlus Buds Pro 2's highest frequency is at 40000Hz, high-frequency response shows how well an audio device generates high human frequencies and if it makes any adjustments to the signal while at it.
Audio Technica ATH TWX9's highest frequency is at 40000Hz, this implies that
both devices generate equal treble
Sound Pressure Level
OnePlus Buds Pro 2
97dB/mW
Audio Technica ATH TWX9 102dB/mW
SPL, is the pressure level of sound, measured in decibels, dB, OnePlus Buds Pro 2's measurement is 97dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
Audio Technica ATH TWX9's sound pressure level measurement is 102dB/mW. The sound pressure level, a device is can be taken differently by separate people, so we need to have the means to get an objective measurement of sound level expressed in numerical terms.
