Has Active Noise Cancellation (Noise Control)
Devialet Gemini
✓
Nuraphone NuraTrue ✓
ANC uses advanced kind of tech to actively cancel noise. How it works, it studies the sound pattern outside and inside the earbud and generates a mirror signal to counter it. In simple terms, it's like taking +1 (sound from your surrounding) then producing -1 (inverted noise) to make 0 which results in a reduced level of noise.
Devialet Gemini have Active Noise Cancellation allowing you to listen at lower levels of volume, good for your ears since you don't have to crank up the earbuds volume to overcome background sounds.
The Nuraphone NuraTrue too have Active Noise Cancellation which makes both devices ideal for plane rides and rush hour travels. The Devialet Gemini and Nuraphone NuraTrue work with different noise cancellation types, pick the noise cancellation type that you prefer for travel or that enhances your relaxation time.
Has Passive Noise Reduction
Devialet Gemini
✓
Nuraphone NuraTrue ✓
The Devialet Gemini stay well in place, creating a sound seal that reduces background sounds and also prevents the device music from leaking out .
Both Nuraphone NuraTrue, and Devialet Gemini have passive noise reduction which means that both reduce ambient noise without using ANC to cancel it out.
Driver Unit Size
Devialet Gemini
10mm
Nuraphone NuraTrue 10mm
Devialet Gemini have a unit size of 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 earbuds, the unit size determines the sound produced by the device.
Nuraphone NuraTrue driver unit is 10mm in diameter,
making both devices similar in how loud their sound can get
, a common assumption 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 are capable of generating louder sound, but this does not indicate that they produce better quality sound.
Lowest Frequency
Devialet Gemini
5Hz
Nuraphone NuraTrue 20Hz
Devialet Gemini's lowest frequency is at 5Hz, low-frequency response measures if and how well an audio component produces low audible frequencies and if it alters the signal on its way through.
Nuraphone NuraTrue's lowest frequency is at 20Hz, this implies that
Devialet Gemini 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 tells how well a particular audio component generates high recognizable 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 generate equal treble
Sound Pressure Level
Devialet Gemini
94dB/mW
Nuraphone NuraTrue 108dB/mW
SPL, is the level of pressure of sound, measured 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. How loud something is can be taken differently by different people, so we need to have the means to get an objective measurement of sound level expressed in numerical terms.
