ANC utilises more advanced technology to reduce ambient sounds. How it works, it studies the sound pattern of incoming noise and then generates a mirror signal to counter it. Simply put, it's like taking +1 (noise) then adding -1 (inverted noise) to make 0 which results in a reduced level of noise.
JBL Live Free 2 have ANC allowing you to listen at lower volume levels, good for your ears as you don't have to crank up the earbuds volume to overcome background sounds.

Driver Unit Size
Energy Sistem Sport 5
14mm
JBL Live Free 2 11mm
JBL Live Free 2 have a unit size of 11mm in diameter, bigger drivers are more powerful, therefor producing better bass.
A driver unit is the component that produces sound in the device, its size determines the loudness of the earbuds.
Energy Sistem Sport 5 driver unit is 14mm in diameter,
making them have a larger driver unit than that of JBL Live Free 2 by 3mm
, many people have a misconception that driver units of a bigger size automatically produce better sound quality.
However, large drivers usually have difficulty producing high frequencies so it's true that, larger drivers can generate louder sound, but this does not imply that they produce better quality sound.
Lowest Frequency
Energy Sistem Sport 5
20Hz
JBL Live Free 2 20Hz
JBL Live Free 2's lowest frequency is at 20Hz, low-frequency response inidcates how well an audio component produces low frequencies that can be heard, and if it makes any changes to the signal on its way through.
Energy Sistem Sport 5's lowest frequency is at 20Hz, this means that
both devices can make sound with equal bass
Highest Frequency
Energy Sistem Sport 5
20000Hz
JBL Live Free 2 20000Hz
The JBL Live Free 2's highest frequency is at 20000Hz, high-frequency response tells how well a particular audio component generates high recognizable frequencies and if it makes any adjustments to the signal on its way through.
Energy Sistem Sport 5's highest frequency is at 20000Hz, this implies that
both devices can generate equal treble
Sound Pressure Level
Energy Sistem Sport 5
✗
JBL Live Free 2 102dB/mW
The sound pressure level, is the pressure level of sound, measured in decibels, dB, JBL Live Free 2's measurement is 102dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
Has A Neodymium Magnet
Energy Sistem Sport 5
✓
JBL Live Free 2 ✗
The Energy Sistem Sport 5 have neodymium magnets, when used in audio devices produce a higher sensitivity and substantial sound output while using less power. They can help generate music at quite a high sound pressure level, using high magnetic flux.
