Has Active Noise Cancellation (Noise Control)
Audio Technica ATH TWX9
✓
Ultimate Ears Drops ✗
ANC makes use of more advanced technology to actively counter noise. How it works, it listens to the sound pattern outside and inside the earbud and after generates a mirror signal to counter it. In simple terms, it's like having +1 (noise) and adding -1 (counter sound by the device) giving 0 therefore "diluting" the noise.
Audio Technica ATH TWX9 have ANC allowing you to listen at lower levels of volume, good for your ears since you don't have to crank up the device volume to outcompete background noise.

Driver Unit Size
Audio Technica ATH TWX9
5.8mm
Ultimate Ears Drops 9.2mm

The driver unit is the component that makes sound in the device, its size determines 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 Ultimate Ears Drops by 3.4mm
, many people have a misconception 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 can generate louder sound, but this does not imply that they deliver better quality sound.
Lowest Frequency
Audio Technica ATH TWX9
20Hz
Ultimate Ears Drops 20Hz
The Ultimate Ears Drops'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 alters the signal on its way through.
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
Ultimate Ears Drops 20000Hz
Ultimate Ears Drops's highest frequency is at 20000Hz, high-frequency response indicates how well a particular audio component makes high human frequencies and if it adjustments to the signal on its way through.
Audio Technica ATH TWX9's highest frequency is at 40000Hz, this implies that
Audio Technica ATH TWX9 can produce a clearer and crispier treble than the Ultimate Ears Drops
Sound Pressure Level
Audio Technica ATH TWX9
102dB/mW
Ultimate Ears Drops 110dB/mW
The sound pressure level, is the level of pressure of sound, measured in decibels, dB, Ultimate Ears Drops's measurement is 110dB/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 something is can be taken differently by separate people, so we need to have the means to get an objective measurement of sound level expressed in numerical terms.
