Has Active Noise Cancellation (Noise Control)
Audio Technica ATH TWX9
✓
JBL Live Free 2 ✓
ANC makes use of advanced technology to reduce unwanted ambient sounds. ANC works when, it detects and analyzes the sound pattern outside and inside the earbud and then generates a mirror signal to counter it. In simple terms, it's like having +1 (noise) then producing -1 (counter sound by the device) to make zero therefore "diluting" the noise.
The 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 have to crank up the device volume to overcome background sounds.
The JBL Live Free 2 too have Active Noise Cancellation making both devices ideal for flights and morning commutes. Each work with different noise cancellation types, pick the mode that you prefer for travel or that enhances your relaxation time.

both devices make sound with equal bass
Highest Frequency
Audio Technica ATH TWX9
40000Hz
JBL Live Free 2 20000Hz

Sound Pressure Level
Audio Technica ATH TWX9
102dB/mW
JBL Live Free 2 102dB/mW
The sound pressure level, is the level of pressure of sound, 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 people, so we need to have a way of getting an objective measurement of sound level expressed in numerical terms.
