Has Active Noise Cancellation (Noise Control)
Nuraphone NuraTrue
✓
JBL Live Free 2 ✓
Active noise cancellation uses advanced technology to reduce unwanted ambient sounds. How it works, it studies the sound pattern of incoming noise and after generates a mirror signal to cancel it out. In simple terms, it's like having +1 (noise) and adding -1 (inverted noise) giving zero therefore "diluting" the noise.
Nuraphone NuraTrue 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 Free 2 too have ANC which makes both devices ideal for plane rides and rush hour travels. The Nuraphone NuraTrue and JBL Live Free 2 work with different noise cancellation modes, pick the mode that suits your commute or that enhances your chill time.

Driver Unit Size
Nuraphone NuraTrue
10mm
JBL Live Free 2 11mm
The Nuraphone NuraTrue driver unit is 10mm 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.
JBL Live Free 2 driver unit is 11mm in diameter,
making them have a larger driver unit than that of Nuraphone NuraTrue by 1mm
, many people have a misconception 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 can generate louder sound, but this does not imply that they deliver better quality sound.
Lowest Frequency
Nuraphone NuraTrue
20Hz
JBL Live Free 2 20Hz
Nuraphone NuraTrue's lowest frequency is at 20Hz, low-frequency response inidcates how well an audio device generates low frequencies that can be heard, and if it alters the signal on its way through.
JBL Live Free 2's lowest frequency is at 20Hz, this implies that
both devices produce equal bass
Highest Frequency
Nuraphone NuraTrue
20000Hz
JBL Live Free 2 20000Hz
Nuraphone NuraTrue's highest frequency is at 20000Hz, high-frequency response shows how well an audio component generates high human frequencies and if it makes any changes to the signal on its way through.
JBL Live Free 2's highest frequency is at 20000Hz, this means that
both devices generate equal treble
Sound Pressure Level
Nuraphone NuraTrue
108dB/mW
JBL Live Free 2 102dB/mW
SPL, is the pressure level of sound, measured in decibels, dB, Nuraphone NuraTrue's measurement is 108dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
JBL Live Free 2's sound pressure level measurement is 102dB/mW. How loud a device is can be considered differently by different persons, so we need to have the means to get an objective measurement of sound level expressed in numerical terms.
