Has Active Noise Cancellation (Noise Control)
Nuraphone NuraTrue

ANC uses more advanced technology to reduce unwanted ambient sounds. ANC works when, it listens to the sound pattern outside and inside the earbud and generates a mirror signal to cancel it out. Simply put, it's like taking +1 (noise) then producing -1 (inverted noise) giving zero resulting in a reduced level of noise.
The Nuraphone NuraTrue have Active Noise Cancellation enabling you to listen at lower volume levels, causing less ear fatigue as you don't need to crank up the earbuds volume to overcome background noise.
The JBL Live Free 2 too have ANC making either of the earbuds ideal for plane rides and rush hour commutes. The Nuraphone NuraTrue and JBL Live Free 2 operate with different noise cancellation settings, pick the setting that you prefer for travel or that suites your relaxation time.

JBL Live Free 2 ✓
Nuraphone NuraTrue sit tightly in place, creating an acoustic seal that reduces background sounds well as preventing the earbuds sound from leaking out .
Both of these devices have passive noise reduction this means that both tone down ambient noise instead of actively using technology to cancel it out.
Driver Unit Size
Nuraphone NuraTrue
10mm
JBL Live Free 2 11mm
The Nuraphone NuraTrue have a unit size of 10mm in diameter, the bigger the unit the more powerful, therefor producing better bass.
A driver unit is the component that produces sound in the earbuds, the unit 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 it's true that, larger drivers can generate louder sound, but this does not indicate that they deliver better quality sound.
Lowest Frequency
Nuraphone NuraTrue
20hz
JBL Live Free 2 20hz
The Nuraphone NuraTrue's lowest frequency is at 20Hz, low-frequency response measures if and how well an audio device generates low recognizable frequencies 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 can make sound with equal bass
Highest Frequency
Nuraphone NuraTrue
20,000hz
JBL Live Free 2 20,000hz
The Nuraphone NuraTrue's highest frequency is at 20,000Hz, high-frequency response indicates how well an audio component makes high audible frequencies and if it changes to the signal while at it.
JBL Live Free 2's highest frequency is at 20,000Hz, this means that
both devices can generate equal treble
Sound Pressure Level
Nuraphone NuraTrue
108db/mw
JBL Live Free 2 102db/mw
The sound pressure level, is the level of pressure 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 something is can be perceived differently by different people, so we need to have the means to get a standard measurement of sound level expressed in numerical terms.
