Has Active Noise Cancellation (Noise Control)
Audio Technica ATH TWX9

Skullcandy Indy Fuel ✗
ANC utilises more advanced technology to reduce ambient sounds. ANC works when, it studies the sound pattern of incoming noise and then inverts the soundwaves to counter it. Simply put, it's like taking +1 (noise) then producing -1 (inverted noise) giving 0 which results in a reduced level of noise.
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 overcome background sounds.
Has Passive Noise Reduction

✓
Skullcandy Indy Fuel ✓
The Audio Technica ATH TWX9 stay tightly in place, creating a sound seal that reduces your environment sounds and also prevents the device sound from leaking out .
Both Skullcandy Indy Fuel, and Audio Technica ATH TWX9 have passive noise reduction this implies that they tone down ambient noise without using technology to cancel it out.
Driver Unit Size
Audio Technica ATH TWX9
5.8mm
Skullcandy Indy Fuel 6mm
Audio Technica ATH TWX9 driver unit is 5.8mm in diameter, the bigger the unit the more powerful, therefor producing better bass.
A driver unit is basically a mini speaker that makes sound in the earbuds, its size corellates with the loudness of the device.
Skullcandy Indy Fuel driver unit is 6mm in diameter,
making them have a larger driver unit than that of Audio Technica ATH TWX9 by 0.2mm
, as many tend to believe 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 can generate louder sound, but this does not mean that they deliver better quality sound.
Lowest Frequency
Audio Technica ATH TWX9
20Hz
Skullcandy Indy Fuel 20Hz
The Audio Technica ATH TWX9's lowest frequency is at 20Hz, low-frequency response inidcates how well an audio device generates low frequencies that can be heard, and if it makes any changes to the signal on its way through.
Skullcandy Indy Fuel's lowest frequency is at 20Hz, this means that
both devices can make sound with equal bass
Highest Frequency
Audio Technica ATH TWX9
40000Hz
Skullcandy Indy Fuel 20000Hz
Audio Technica ATH TWX9's highest frequency is at 40000Hz, high-frequency response indicates how well a particular audio device produces high recognizable frequencies and if it changes to the signal on its way through.
Skullcandy Indy Fuel's highest frequency is at 20000Hz, this implies that
Audio Technica ATH TWX9 can generate a clearer and crispier treble than the Skullcandy Indy Fuel
Sound Pressure Level
Audio Technica ATH TWX9
102dB/mW
Skullcandy Indy Fuel 105dB/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.
Skullcandy Indy Fuel's sound pressure level measurement is 105dB/mW. How loud something is can be taken differently by different people, so we need to have a way of getting a standard measurement of sound level expressed in numerical terms.
