Has Active Noise Cancellation (Noise Control)

JBL Reflect Aero TWS ✓
ANC utilises more advanced kind of tech to reduce ambient sounds. How it works, it listens to the sound pattern of incoming noise and then generates a mirror signal to counter it. Simply put, it's like having +1 (noise) and adding -1 (inverted noise) to make zero thus "diluting" the noise.
The Audio Technica ATH TWX9 have Active Noise Cancellation enabling you to listen at lower levels of volume, causing less ear fatigue since you don't need to crank up the earbuds volume to outcompete background noise.
The JBL Reflect Aero TWS too have Active Noise Cancellation making either of the devices ideal for plane rides and rush hour commutes. Each operate with different noise cancellation modes, pick the setting that suits your travel or that enhances your chill time.
Has Passive Noise Reduction

JBL Reflect Aero TWS ✓
The Audio Technica ATH TWX9 sit well in place, this creates a sound covering that reduces your environment sounds and also prevents the earbuds music from leaking out .
Both of these devices have passive noise reduction which means that both reduce ambient noise instead of actively using ANC to cancel it out.
Driver Unit Size
Audio Technica ATH TWX9
5.8mm
JBL Reflect Aero TWS 6.8mm
The Audio Technica ATH TWX9 have a unit size of 5.8mm in diameter, the bigger the unit the more powerful, and can produce better bass.
A driver unit is the component that produces sound in the earbuds, its size dictates the sound made by the device.
JBL Reflect Aero TWS driver unit is 6.8mm in diameter,
making them have a larger driver unit than that of Audio Technica ATH TWX9 by 1mm
, many people have a misconception 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 imply that they deliver better quality sound.
Lowest Frequency
Audio Technica ATH TWX9
20Hz
JBL Reflect Aero TWS 20Hz
The Audio Technica ATH TWX9's lowest frequency is at 20Hz, low-frequency response inidcates how well a particular audio device produces low frequencies that can be heard, and if it alters the signal on its way through.
JBL Reflect Aero TWS's lowest frequency is at 20Hz, this implies that
both devices can produce equal bass
Highest Frequency
Audio Technica ATH TWX9
40000Hz
JBL Reflect Aero TWS 20000Hz
The Audio Technica ATH TWX9's highest frequency is at 40000Hz, high-frequency response tells how well an audio device generates high audible frequencies and if it changes to the signal on its way through.
JBL Reflect Aero TWS's highest frequency is at 20000Hz, this implies that
Audio Technica ATH TWX9 generate a clearer and crispier treble than the JBL Reflect Aero TWS
Sound Pressure Level
Audio Technica ATH TWX9
102dB/mW
JBL Reflect Aero TWS 99dB/mW
SPL, is the level of pressure 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.
JBL Reflect Aero TWS's sound pressure level measurement is 99dB/mW. How loud a device is can be considered differently by different persons, so we need to have the means to get an objective measurement of sound level expressed in numerical terms.
