Has Active Noise Cancellation (Noise Control)
JBL Live Free 2
✓
1More Aero ✓
Active noise cancellation makes use of 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. In simple terms, it's like having +1 (sound from your surrounding) and adding -1 (counter sound by the device) giving 0 hence "diluting" the noise.
The 1More Aero have Active Noise Cancellation allowing you to listen at lower volume levels, causing less ear fatigue as you don't need to crank up the device volume to overcome background sounds.
The JBL Live Free 2 too have ANC which makes both earbuds ideal for flights and rush hour commutes. Each operate with different noise cancellation modes, pick the mode that suits your travel or that enhances your relaxation time.

Driver Unit Size
JBL Live Free 2
11mm
1More Aero 10mm
1More Aero driver unit is 10mm in diameter, bigger drivers are more powerful, therefor producing better bass.
A driver unit is basically a mini speaker that produces sound in the earbuds, the unit size determines the loudness of the device.
JBL Live Free 2 driver unit is 11mm in diameter,
making them have a larger driver unit than that of 1More Aero by 1mm
, a common assumption 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 mean that they deliver better quality sound.
Lowest Frequency
JBL Live Free 2
20Hz
1More Aero 20Hz
1More Aero's lowest frequency is at 20Hz, low-frequency response inidcates how well a particular audio component produces low frequencies that can be heard, and if it makes any changes to the signal while at it.

both devices produce equal bass
Highest Frequency
JBL Live Free 2
20000Hz
1More Aero 20000Hz
1More Aero's highest frequency is at 20000Hz, high-frequency response shows how well a particular audio device produces high audible frequencies and if it makes any adjustments to the signal while at it.
JBL Live Free 2's highest frequency is at 20000Hz, this implies that
both devices produce equal treble
Sound Pressure Level
JBL Live Free 2
102dB/mW
1More Aero ✗
