Has Active Noise Cancellation (Noise Control)

JBL Live Free 2 ✓
Active noise cancellation makes use of advanced technology to actively counter noise. How it works, it studies the sound pattern of incoming noise and then generates a mirror signal to cancel it out. In simple terms, it's like taking +1 (sound from your surrounding) then adding -1 (inverted noise) giving 0 hence "diluting" the noise.
The JBL Live Free 2 have ANC enabling you to listen at lower levels of volume, good for your ears since you don't need to crank up the device volume to outcompete background noise.
JBL Live Pro 2 too have ANC making either of the devices ideal for plane rides and rush hour commutes. Each work with different noise cancellation settings, pick the mode that suits your commute or that enhances your chill time.

JBL Live Pro 2 driver unit is 11mm in diameter,
making both JBL Live Pro 2, and JBL Live Free 2 similar in how loud their sound can get
, as many tend to believe that driver units of a bigger size automatically produce better sound quality.

Lowest Frequency
JBL Live Pro 2
20Hz
JBL Live Free 2 20Hz
The 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 while at it.
JBL Live Pro 2's lowest frequency is at 20Hz, this means that
both devices make sound with equal bass
Highest Frequency
JBL Live Pro 2
20000Hz
JBL Live Free 2 20000Hz
The JBL Live Free 2's highest frequency is at 20000Hz, high-frequency response measures if and how well an audio component produces high human frequencies and if it changes to the signal while at it.
JBL Live Pro 2's highest frequency is at 20000Hz, this means that
both devices generate equal treble
Sound Pressure Level
JBL Live Pro 2
93dB/mW
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.
JBL Live Pro 2's sound pressure level measurement is 93dB/mW. How loud something is can be taken differently by different persons, so we need to have the means to get a standard measurement of sound level expressed in numerical terms.
