Nuraphone NuraTrue ✓
Active noise cancellation makes use of advanced technology to actively cancel noise. ANC works when, it listens to the sound pattern outside and inside the earbud and then inverts the soundwaves to cancel it out. Simply put, it's like having +1 (sound from your surrounding) and producing -1 (counter sound by the device) giving 0 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 device volume to overcome background noise.
Bose QuietComfort Earbuds II too have ANC which makes either of the devices ideal for plane rides and morning commutes. Each operate with different noise cancellation settings, pick the noise cancellation type that suits your travel or that enhances your relaxation time.

Driver Unit Size
Bose QuietComfort Earbuds II
9.3mm
Nuraphone NuraTrue 10mm
The Nuraphone NuraTrue driver unit is 10mm in diameter, bigger drivers are more powerful, and can produce better bass.
The driver unit is basically a mini speaker that produces sound in the device, the unit size determines the loudness of the earbuds.
Bose QuietComfort Earbuds II driver unit is 9.3mm in diameter,
which means that they have a smaller driver unit than that of Nuraphone NuraTrue by 0.7mm
, a common assumption 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
Bose QuietComfort Earbuds II
20Hz
Nuraphone NuraTrue 20Hz
Nuraphone NuraTrue's lowest frequency is at 20Hz, low-frequency response measures if and how well an audio device generates low frequencies that can be heard, and if it makes any changes to the signal while at it.
Bose QuietComfort Earbuds II's lowest frequency is at 20Hz, this means that
both devices can make sound with equal bass
Highest Frequency
Bose QuietComfort Earbuds II
20000Hz
Nuraphone NuraTrue 20000Hz
The Nuraphone NuraTrue's highest frequency is at 20000Hz, high-frequency response indicates how well an audio component generates high audible frequencies and if it makes any changes to the signal while at it.
Bose QuietComfort Earbuds II's highest frequency is at 20000Hz, this implies that
both devices can produce equal treble
Sound Pressure Level
