Has Active Noise Cancellation (Noise Control)

JBL Live Free 2 ✓
ANC uses more 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 taking +1 (noise) and adding -1 (inverted noise) to make 0 hence "diluting" the noise.
The JBL Live Free 2 have Active Noise Cancellation allowing you to listen at lower levels of volume, good for your ears as you don't have to crank up the device volume to outcompete background sounds.

A driver unit is the component that produces sound in the device, its size dictates the sound made by 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
, as many tend to believe 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 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 a particular audio device generates 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
Energy Sistem Sport 5
20000Hz
JBL Live Free 2 20000Hz
The JBL Live Free 2's highest frequency is at 20000Hz, high-frequency response indicates how well a particular audio component generates high audible 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 level of pressure 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 earbuds produce a higher sensitivity and substantial sound output while using less power. They can help produce music at quite a high sound pressure level, using high magnetic flux.
