Has Active Noise Cancellation (Noise Control)
Devialet Gemini
✓
Nuraphone NuraTrue ✓
ANC utilises more advanced technology to reduce unwanted ambient sounds. How it works, it detects and analyzes the sound pattern outside and inside the earbud and after inverts the soundwaves to cancel it out. Simply put, it's like having +1 (noise) then producing -1 (inverted noise) to make zero hence "diluting" the noise.
The Devialet Gemini have Active Noise Cancellation allowing you to listen at lower levels of volume, causing less ear fatigue since you don't have to crank up the device volume to overcome background sounds.
Nuraphone NuraTrue too have ANC which makes either of the earbuds ideal for flights and rush hour commutes. The Devialet Gemini and Nuraphone NuraTrue work with different noise cancellation types, pick the noise cancellation type that suits your commute or that enhances your relaxation time.
Has Passive Noise Reduction
Devialet Gemini
✓
Nuraphone NuraTrue ✓
Devialet Gemini sit tightly in place, this creates an acoustic seal that tones down background sounds well as preventing the device sound from leaking out .
Both Nuraphone NuraTrue, and Devialet Gemini have passive noise reduction this means that they tone down ambient noise instead of actively using technology to cancel it out.
Driver Unit Size
Devialet Gemini
10mm
Nuraphone NuraTrue 10mm
Devialet Gemini driver unit is 10mm in diameter, bigger drivers are more powerful, therefor producing better bass.
A driver unit is basically a mini speaker that makes sound in the device, its size dictates the loudness of the earbuds.
Nuraphone NuraTrue driver unit is 10mm in diameter,
making both devices similar in how loud their sound gets
, as many tend to believe that driver units of a bigger size automatically produce better sound quality.
However, large drivers usually have difficulty producing high frequencies so yeah, larger drivers can generate louder sound, but this does not mean that they deliver better quality sound.
Lowest Frequency
Devialet Gemini
5Hz
Nuraphone NuraTrue 20Hz
The Devialet Gemini's lowest frequency is at 5Hz, low-frequency response inidcates how well an audio component produces low recognizable frequencies and if it alters the signal while at it.
Nuraphone NuraTrue's lowest frequency is at 20Hz, this implies that
Devialet Gemini can produce a juicier bass than the Nuraphone NuraTrue
Highest Frequency
Devialet Gemini
20000Hz
Nuraphone NuraTrue 20000Hz
Devialet Gemini's highest frequency is at 20000Hz, high-frequency response shows how well a particular audio component makes high audible frequencies and if it makes any adjustments to the signal on its way through.
Nuraphone NuraTrue's highest frequency is at 20000Hz, this implies that
both devices can generate equal treble
Sound Pressure Level
Devialet Gemini
94dB/mW
Nuraphone NuraTrue 108dB/mW
SPL, is the pressure level of sound, in decibels, dB, Devialet Gemini's measurement is 94dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
Nuraphone NuraTrue's sound pressure level measurement is 108dB/mW. The sound pressure level, a device is can be perceived differently by different people, so we need to have the means to get an objective measurement of sound level expressed in numerical terms.
