Has Active Noise Cancellation (Noise Control)
OnePlus Buds Pro 2
✓
Audio Technica ATH TWX9 ✓
Active noise cancellation utilises advanced technology to reduce unwanted ambient sounds. ANC works when, it listens to the sound pattern outside and inside the earbud and inverts the soundwaves to counter it. Simply put, it's like having +1 (noise) and adding -1 (counter sound by the device) giving zero thus "diluting" the noise.
The OnePlus Buds Pro 2 have Active Noise Cancellation allowing you to listen at lower levels of volume, causing less ear fatigue since you don't need to crank up the device volume to overcome background sounds.
The Audio Technica ATH TWX9 too have ANC which makes either of the devices ideal for flights and rush hour travels. Each work with different noise cancellation settings, pick the mode that suits your travel or that enhances your relaxation time.
Has Passive Noise Reduction

✓
Audio Technica ATH TWX9 ✓
The OnePlus Buds Pro 2 sit tightly in place, creating a sound seal that reduces your environment sounds and also prevents the device music from leaking out at the same.
Both of these devices have passive noise reduction this means that both limit ambient noise without using technology to cancel it out.
Driver Unit Size
OnePlus Buds Pro 2
11mm
Audio Technica ATH TWX9 5.8mm
The OnePlus Buds Pro 2 have a unit size of 11mm in diameter, bigger drivers are more powerful, therefor producing better bass.
The driver unit is the component that makes sound in the device, the unit 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 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 yes, larger drivers are capable of generating louder sound, but this does not indicate that they produce better quality sound.
Lowest Frequency
OnePlus Buds Pro 2
10hz
Audio Technica ATH TWX9 20hz
The OnePlus Buds Pro 2's lowest frequency is at 10Hz, low-frequency response inidcates 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.
Audio Technica ATH TWX9's lowest frequency is at 20Hz, this implies that
OnePlus Buds Pro 2 can make sound with a juicier bass than the Audio Technica ATH TWX9
Highest Frequency
OnePlus Buds Pro 2
40,000hz
Audio Technica ATH TWX9 40,000hz
The OnePlus Buds Pro 2's highest frequency is at 40,000Hz, high-frequency response measures if and how well a particular audio component generates high human frequencies and if it changes to the signal on its way through.
Audio Technica ATH TWX9's highest frequency is at 40,000Hz, this means that
both devices produce equal treble
Sound Pressure Level
OnePlus Buds Pro 2
97db/mw
Audio Technica ATH TWX9 102db/mw
The sound pressure level, is the pressure level of sound, 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. How loud a device is can be taken differently by separate persons, so we need to have a way of getting an objective measurement of sound level expressed in numerical terms.
