Has Active Noise Cancellation (Noise Control)
Audio Technica ATH TWX9
✓
Powerbeats Pro ✗
Active noise cancellation uses advanced technology to actively cancel noise. How it works, it studies the sound pattern of incoming noise and inverts the soundwaves to cancel it out. Simply put, it's like taking +1 (noise) and adding -1 (inverted noise) giving zero therefore "diluting" the noise.
Audio Technica ATH TWX9 have ANC allowing you to listen at lower levels of volume, causing less ear fatigue since you don't have to crank up the earbuds volume to overcome background noise.
Has Passive Noise Reduction

Both of these devices have passive noise reduction this implies that they tone down ambient noise instead of actively using ANC to cancel it out.
Driver Unit Size
Audio Technica ATH TWX9
5.8mm
Powerbeats Pro 12mm

which implies that they have a smaller driver unit than that of Powerbeats Pro by 6.2mm
, many people have a misconception that driver units of a bigger size automatically produce better sound quality.

Lowest Frequency
Audio Technica ATH TWX9
20hz
Powerbeats Pro 10hz
Powerbeats Pro's lowest frequency is at 10Hz, low-frequency response inidcates how well a particular audio device generates low audible frequencies and if it alters the signal on its way through.
Audio Technica ATH TWX9's lowest frequency is at 20Hz, this means that
Powerbeats Pro can produce a juicier bass than the Audio Technica ATH TWX9
Highest Frequency
Audio Technica ATH TWX9
40,000hz
Powerbeats Pro ✗
The Audio Technica ATH TWX9's highest frequency is at 40,000Hz, high-frequency response tells how well an audio device generates high recognizable frequencies and if it adjustments to the signal on its way through.
Sound Pressure Level
Audio Technica ATH TWX9
102db/mw
Powerbeats Pro ✗
The sound pressure level, 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.
