A breakdown of the review per specifications


Ingress Protection (Ip) Rating

Devialet Gemini IPX4
Tozo T10S IPX8

IP ratings refer to the rating of protection given by a casing, against dust and liquids. In the format of IPXX, 'X' represents a number The first value of the IP rating refers to protection against solids such as dust, while the second refers to resistance against liquids (water).

Having a value of IPX4, the Devialet Gemini's rating for solids indicates that no data available to specify a protection rating, and the second number of 4 means that they can withstand low pressure spray similar to that of a shower head when tilted at 180° for 10 minutes.

In comparison to the Devialet Gemini, Tozo T10S have a rating of IPX8 meaning that we are not yet certain of their rating with solids (dust) and that of liquids is that, Devialet Gemini has a lower liquid rating than Tozo T10S


Devialet Gemini 8g
Tozo T10S 10g

Devialet Gemini have a weight of 8g . We consider a lower weight better because lighter devices are more comfortable to move with.

Tozo T10S, at 10g are heavier than the Devialet Gemini with a difference of 2g

Has No Wires Or Cables

Devialet Gemini
Tozo T10S

For a device to be true wireless it must have no wires connecting any part of the device together, Devialet Gemini are true wireless for this case since they don't have wires. This is a key distinction since wireless earbuds have wires connecting the two earbuds .

Tozo T10S also is true wireless because it doesn't have cables connecting the two earbuds together.

Sweat Resistance

Devialet Gemini
Tozo T10S

Devialet Gemini have sweat resistance

Tozo T10S's resistance to sweat makes both devices fit for use during long-distance running, marathons, cardio sweat workouts , etc

Has Stereo Speakers

Devialet Gemini
Tozo T10S

Devialet Gemini have stereo speakers, devices with stereo speakers deliver sound from separate channels on both left and right sides, creating a richer sound and a better listening experience.

The Tozo T10S also have stereo speakers

Waterproof Depth Rating

Devialet Gemini
Tozo T10S 1meters

Tozo T10S are rated 1meters any depth more than that they will be damaged. Devices that can withstand more water pressure are better for diving.

Sound Quality

Has Active Noise Cancellation (Noise Control)

Devialet Gemini
Tozo T10S

Active noise cancellation uses advanced kind of tech to reduce ambient sounds. ANC works when, it listens to the sound pattern outside and inside the earbud and then generates a mirror signal to counter it. In simple terms, it's like having +1 (noise) and producing -1 (counter sound by the device) giving zero therefore "diluting" the noise.

The Devialet Gemini have Active Noise Cancellation allowing you to listen at lower levels of volume, good for your ears since you don't need to crank up the earbuds volume to outcompete background sounds.

Has Passive Noise Reduction

Devialet Gemini
Tozo T10S

Devialet Gemini sit well in place, creating an acoustic covering that tones down background noise and also prevents the earbuds voice audio from leaking out .

Both of these devices have passive noise reduction this implies that they tone down ambient noise without using technology to cancel it out.

Driver Unit Size

Devialet Gemini 10mm
Tozo T10S 8mm

Devialet Gemini driver unit is 10mm in diameter, the bigger the unit the more powerful, therefor producing better bass. A driver unit is basically a mini speaker that makes sound in the earbuds, the unit size corellates with the loudness of the earbuds.

Tozo T10S driver unit is 8mm in diameter, which implies that they have a smaller driver unit than that of Devialet Gemini by 2mm , 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 mean that they deliver better quality sound.

Lowest Frequency

Devialet Gemini 5Hz
Tozo T10S 20Hz

Devialet Gemini's lowest frequency is at 5Hz, low-frequency response inidcates how well a particular audio component generates low frequencies that can be heard, and if it alters the signal while at it.

Highest Frequency

Devialet Gemini 20000Hz
Tozo T10S 20000Hz

The Devialet Gemini's highest frequency is at 20000Hz, high-frequency response shows how well a particular audio device produces high audible frequencies and if it adjustments to the signal on its way through.

Tozo T10S's highest frequency is at 20000Hz, this means that both devices can generate equal treble
