Has Active Noise Cancellation (Noise Control)
Audio Technica ATH TWX9
✓
JBL Tune 225TWS ✗
ANC utilises advanced technology to actively cancel noise. How it works, it detects and analyzes the sound pattern of incoming noise and generates a mirror signal to counter it. In simple terms, it's like having +1 (sound from your surrounding) and producing -1 (inverted noise) giving zero hence "diluting" the noise.
The Audio Technica ATH TWX9 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 overcome background sounds.
Has Passive Noise Reduction
Audio Technica ATH TWX9
✓
JBL Tune 225TWS ✓
JBL Tune 225TWS stay well in place, this creates an acoustic covering that reduces background sounds and also prevents the earbuds sound from leaking out .
Both Audio Technica ATH TWX9, and JBL Tune 225TWS have passive noise reduction which implies that both reduce ambient noise without using technology to cancel it out.
Driver Unit Size
Audio Technica ATH TWX9
5.8mm
JBL Tune 225TWS 12mm
JBL Tune 225TWS have a unit size of 12mm in diameter, bigger drivers are more powerful, therefor producing better bass.
A driver unit is the component that makes sound in the earbuds, the unit size corellates with the sound made 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 JBL Tune 225TWS by 6.2mm
, as many tend to believe that driver units of a bigger size automatically produce better sound quality.
However, large drivers find it difficult to produce high frequencies so yeah, larger drivers are capable of generating louder sound, but this does not imply that they produce better quality sound.
Lowest Frequency
Audio Technica ATH TWX9
20Hz
JBL Tune 225TWS 20Hz
The JBL Tune 225TWS's lowest frequency is at 20Hz, low-frequency response inidcates how well an audio component generates low audible frequencies and if it makes any changes to the signal while at it.
Audio Technica ATH TWX9's lowest frequency is at 20Hz, this implies that
both devices can make sound with equal bass
Highest Frequency
Audio Technica ATH TWX9
40000Hz
JBL Tune 225TWS 20000Hz
JBL Tune 225TWS's highest frequency is at 20000Hz, high-frequency response shows how well a particular audio device makes high audible frequencies and if it adjustments to the signal on its way through.
Audio Technica ATH TWX9's highest frequency is at 40000Hz, this means that
Audio Technica ATH TWX9 produce a clearer and crispier treble than the JBL Tune 225TWS
Sound Pressure Level
Audio Technica ATH TWX9
102dB/mW
JBL Tune 225TWS 105dB/mW
The sound pressure level, is the level of pressure of sound, in decibels, dB, JBL Tune 225TWS's measurement is 105dB/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 considered differently by separate persons, so we need to have the means to get a standard measurement of sound level expressed in numerical terms.
