A breakdown of the review per specifications


Ingress Protection (Ip) Rating

Devialet Gemini IPX4
Nuraphone NuraTrue IPX4

Ingress protection ratings is the rating of protection given by an enclosure, against solids and water. In the format of IPXX, 'X' represents a number The first value of the IP rating refers to protection against solids say dust, while the second refers to protection against liquids (sweat).

Scoring IPX4, the Devialet Gemini's rating for solids indicates that no data available to specify a protection rating, and of liquids that they can withstand low pressure spray similar to that of a shower head when tilted at 180° for 10 minutes.

Compared to the Devialet Gemini, Nuraphone NuraTrue have a rating of IPX4 meaning that we are not yet certain of their rating with solids (dust) and that of liquids is that, they both have the same rating against liquids


Devialet Gemini 8g
Nuraphone NuraTrue 14.8g

Devialet Gemini have a weight of 8g . We consider a lower weight better for the reason that lighter devices are more comfortable to transport.

The Nuraphone NuraTrue, at 14.8g weigh more than the Devialet Gemini with a difference of 6.8g

Has No Wires Or Cables

Devialet Gemini
Nuraphone NuraTrue

True wireless devices have no cables connecting any part of the device together, Devialet Gemini are true wireless for this case since they have no cables. This is an important difference as some wireless earbuds have cables connecting the pair of earbuds .

Nuraphone NuraTrue also is true wireless since it has no wires connecting the two earbuds .

Sweat Resistance

Devialet Gemini
Nuraphone NuraTrue

Devialet Gemini have sweat resistance

Nuraphone NuraTrue's resistance to sweat makes both devices good for use during long-distance running, marathons, training in workout bodysuits, etc

Sound Quality

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.
