Has Active Noise Cancellation (Noise Control)

ANC makes use of advanced technology to actively cancel noise. How it works, it listens to the sound pattern outside and inside the earbud and after generates a mirror signal to counter it. Simply put, it's like taking +1 (noise) and producing -1 (counter sound by the device) giving zero hence "diluting" the noise.
JBL Live Free 2 have ANC enabling you to listen at lower levels of volume, causing less ear fatigue since you don't have to crank up the earbuds volume to outcompete background sounds.
JBL Live Pro 2 too have ANC making both devices ideal for flights and rush hour commutes. The JBL Live Free 2 and JBL Live Pro 2 operate with different noise cancellation settings, pick the noise cancellation type that suits your commute or that enhances your relaxation time.

JBL Live Pro 2 driver unit is 11mm in diameter,
making both devices similar in how loud their sound can get
, 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 are capable of generating louder sound, but this does not imply that they produce better quality sound.

both devices can generate equal treble
Sound Pressure Level
JBL Live Pro 2
93dB/mW
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.
JBL Live Pro 2's sound pressure level measurement is 93dB/mW. The sound pressure level, something is can be considered differently by different people, so we need to have a way of getting a standard measurement of sound level expressed in numerical terms.
