Has Active Noise Cancellation (Noise Control)
Audio Technica ATH TWX9
✓
JBL Live Free 2 ✓
ANC utilises more advanced kind of tech to reduce ambient sounds. How it works, it studies the sound pattern of incoming noise and then generates a mirror signal to counter it. Simply put, it's like having +1 (noise) and producing -1 (inverted noise) to make zero resulting in a reduced level of noise.
Audio Technica ATH TWX9 have Active Noise Cancellation allowing you to listen at lower levels of volume, causing less ear fatigue as you don't need to crank up the device volume to overcome background noise.
The JBL Live Free 2 too have Active Noise Cancellation making both devices ideal for plane rides and rush hour commutes. Each operate with different noise cancellation settings, pick the noise cancellation type that you prefer for commute or that suites your chill time.
Has Passive Noise Reduction
Audio Technica ATH TWX9
✓
JBL Live Free 2 ✓
Audio Technica ATH TWX9 sit tightly in place, creating an acoustic covering that reduces background noise well as preventing the earbuds sound from leaking out .
Both JBL Live Free 2, and Audio Technica ATH TWX9 have passive noise reduction which implies that they tone down ambient noise without using ANC to cancel it out.
Driver Unit Size
Audio Technica ATH TWX9
5.8mm
JBL Live Free 2 11mm
Audio Technica ATH TWX9 have a unit size of 5.8mm in diameter, bigger drivers are more powerful, therefor producing better bass.
A driver unit is the component that produces sound in the device, its size corellates with the loudness of the earbuds.
JBL Live Free 2 driver unit is 11mm in diameter,
making them have a larger driver unit than that of Audio Technica ATH TWX9 by 5.2mm
, a common assumption that driver units of a bigger size automatically produce better sound quality.
However, large drivers find it difficult to produce 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
JBL Live Free 2 20Hz
Audio Technica ATH TWX9's lowest frequency is at 20Hz, low-frequency response measures if and how well a particular audio component generates low audible frequencies and if it alters the signal while at it.
JBL Live Free 2's lowest frequency is at 20Hz, this means that
both devices can produce equal bass
Highest Frequency
Audio Technica ATH TWX9
40000Hz
JBL Live Free 2 20000Hz
The Audio Technica ATH TWX9's highest frequency is at 40000Hz, high-frequency response indicates how well an audio component produces high recognizable frequencies and if it adjustments to the signal while at it.
JBL Live Free 2's highest frequency is at 20000Hz, this means that
Audio Technica ATH TWX9 can generate a clearer and crispier treble than the JBL Live Free 2
Sound Pressure Level
Audio Technica ATH TWX9
102dB/mW
JBL Live Free 2 102dB/mW
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.
JBL Live Free 2's sound pressure level measurement is 102dB/mW. The sound pressure level, something 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.
