Has Active Noise Cancellation (Noise Control)
JBL Live Pro 2
✓
JBL LIVE 300 ✗
Active noise cancellation utilises advanced technology to reduce ambient sounds. How it works, it studies the sound pattern of incoming noise and inverts the soundwaves to counter it. Simply put, it's like having +1 (sound from your surrounding) and producing -1 (counter sound by the device) to make zero hence "diluting" the noise.
The JBL Live Pro 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 outcompete background sounds.

The JBL LIVE 300 sit tightly in place, this creates a sound seal that reduces your environment sounds and also prevents the device music from leaking out .
Both of these devices have passive noise reduction which implies that they tone down ambient noise without using technology to cancel it out.
Driver Unit Size
JBL Live Pro 2
11mm
JBL LIVE 300 5.8mm
JBL LIVE 300 have a unit size of 5.8mm in diameter, the bigger the unit the more powerful, therefor producing better bass.
A driver unit is the component that makes sound in the device, the unit size corellates with the loudness of the device.
JBL Live Pro 2 driver unit is 11mm in diameter,
making them have a larger driver unit than that of JBL LIVE 300 by 5.2mm
, 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 deliver better quality sound.
Lowest Frequency
JBL Live Pro 2
20Hz
JBL LIVE 300 20Hz
The JBL LIVE 300's lowest frequency is at 20Hz, low-frequency response measures if and how well a particular audio component generates low recognizable frequencies and if it alters the signal on its way through.
JBL Live Pro 2's lowest frequency is at 20Hz, this means that
both devices can make sound with equal bass
Highest Frequency
JBL Live Pro 2
20000Hz
JBL LIVE 300 20000Hz
JBL LIVE 300's highest frequency is at 20000Hz, high-frequency response shows how well an audio device makes high human frequencies and if it makes any adjustments to the signal on its way through.
JBL Live Pro 2's highest frequency is at 20000Hz, this implies that
both devices can produce equal treble
Sound Pressure Level
JBL Live Pro 2
93dB/mW
JBL LIVE 300 95dB/mW
The sound pressure level, is the level of pressure of sound, in decibels, dB, JBL LIVE 300's measurement is 95dB/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 a device is can be considered differently by different persons, so we need to have a way of getting an objective measurement of sound level expressed in numerical terms.
