Devialet Gemini review: TWS headphones with French charm


</ img>

Devialet decided to enter a completely new segment of TWS headphones. Debut went well

successful.Devialet Gemini is a very interesting and functional model, albeit not a massive one due to the cost. Headphones sound good and “expensive” for their form factor. They are equipped with an effective active noise reduction system and are protected against moisture according to the IPX4 standard. They are light, compact and have a shallow in-ear fit that will surely appeal to some of the audience. Among the additional advantages, it is worth mentioning the functionality: in addition to the standard equalizer, there is an auto-pause, wireless charging, and also a check of the correct position in the ears. First of all, an impressive cost of about 11,500 UAH can stop you from buying. Of the minor complaints - a modest battery life and a low volume margin.

If we talk about competitors, then the most logical(considering the cost) are Sony WF-1000XM4: slightly outperform Devialet Gemini in terms of noise reduction and autonomy, but significantly lose in sound quality. And Noble Audio FoKus Pro, the sound of which seems to me both more interesting in general, and the study of frequencies is more detailed. Plus, they last longer on a single battery charge and are definitely more comfortable if you like a deep fit in your ears. On the side of Devialet Gemini is the presence of active noise reduction and wider functionality.

What is Devialet known for?


</ img>

Devialet started its work in 2007in France. The first device was the D-Premier amplifier, which was released in 2010. A couple of years later, it was updated and the line of amplifiers was replenished with two more models. The main fame of the company was due to its very unusual and technologically advanced wireless acoustics. The first model was the Devialet Phantom, which was announced in 2014. At the moment, the company produces amplifiers, soundbars, a whole line of expensive Devialet Phantom acoustics with an impressive sound, which all music lovers probably know about. To all this, the first Devialet Gemini wireless TWS headphones were added, in which the company used a bunch of its proprietary developments. Today we will get to know them better and find out what happened in the end.

What is in the box?

Devialet Gemini are packed in comparativelya small square black box with a picture of headphones from the “facade” and a list of the main technical features on the back. Inside there are headphones in a charging case, a USB Type-C cable, three additional pairs of silicone eartips of different sizes, and a copious amount of documentation.

What do Devialet Gemini look like?


</ img>

Devialet Gemini made of black plasticdifferent texture. The outer parts are glossy, everything else is a nice soft touch. The headphones are very compact and lightweight, in shape and design they resemble the aforementioned Devialet acoustics of the Phantom line.

On the outside of each earpiece is a flattouch pad with gray Devialet logo. Nearby in the recess is a hole for the microphones of the active noise reduction system. On the upper part - the designations "left" and "right".


</ img>

On the inside, four magnetic contacts, a sensor for the presence of an earpiece in the ear and small holes are visible. Apparently compensatory.

Below - one more microphone hole.

The sound guides in Devialet Gemini are quite short, butdiameter standard or close to standard. Third-party nozzles hold quite well, including thanks to the edging for additional fixation. Protective mesh silver color with a rather unusual pattern.

Devialet Gemini are protected from moisture according to the standardIPX4. And this means that you can play sports in them without problems, nothing will happen to them from sweat. Visually, the headphones look good and expensive, but there are some minor quibbles about convenience. We will talk about this a little lower.


</ img>

The charging case is large, also made of blacksoft-touch plastic. Due to the shape and impressive dimensions, it will not work to carry it in a jeans pocket. In winter, it is possible to stuff it into the inner pocket of a jacket. There is a button on the front of the case to check the charge or switch the headphones to pairing mode.

The case is opened by sliding the top cover.There is an excellent clear finishing mechanism that works in both directions. The process of opening and closing causes great aesthetic pleasure. Inside there are only places for headphones with contacts. The magnets are quite strong and the headphones hold securely even when shaking.

On the back is a Type-C port for charging. Qi wireless is also supported.

How convenient is it to use Devialet Gemini?

Thanks to its compact shape and smallweight, using Devialet Gemini is quite convenient. They do not press anywhere and do not strain during prolonged use, they do not fall out of the ears while running. The only point of contention is a very shallow landing. This is a very individual and taste feature. But I constantly subconsciously tried to shove the headphones deeper. Although with passive soundproofing, everything is in perfect order.


</ img>

The headphones use Bluetooth 5.0.There are no problems with signal stability: no stuttering or interruptions in almost all situations. It is possible that there will be some difficulties in rooms with a large number of Wi-Fi networks, but I have not encountered it during use. There is no multipoint function. Only SBC, AAC and aptX codecs are supported. aptX Adaptive, aptX HD and LDAC are not, although this is not critical.

To pair your headphones with a source, you need tojust take it out of the case. There is touch control, but the touch pad does not occupy the entire outer area of ​​the earphone. Which entails periodic misses, especially when used on the go. In the standard version: one short touch of any earphone - play / pause. Double tap - activate the voice assistant and answer the call. Long touch - Switch between noise reduction and transparency modes. In the proprietary Devialet Gemini application, you can update the firmware of the headphones, view the battery level, switch noise reduction modes, adjust the control, equalizer, channel balance and enable autopause when the earphone is removed from the ear. Of the interesting features - checking the fit of the headphones: a melody is played, and the microphones determine how correctly the headphones are inserted.

What about the sound quality, noise reduction and microphone?

The company does not specify whichemitters and in what configuration they are used, so obviously one dynamic per earpiece. But several proprietary technologies are mentioned at once, which serve to improve the sound. EAM (Ear Active Matching) analyzes the shape of the user's ears in real time (10,000 times per second) and adjusts the sound accordingly. IDC (Internal Delay Compensation) is a technology for internal delay compensation created by the noise reduction system. They promise higher noise reduction efficiency, especially at high frequencies. And PBA (Pressure Balance Architecture): cascading decompression chambers maintain optimal internal pressure to reduce fatigue during long listening sessions.

Devialet Gemini sound very nice, naturaland pretty detailed. Particularly pleased with the natural sound of live instruments. There are no significant peaks or dips over the entire frequency range. But, it is worth noting that in terms of musical genres, Devialet Gemini is still not suitable for everything. The overall mood of the sound is calm and tidy. It is very pleasant to listen to classical, jazz and other “light” styles of music, as well as diverse electronics in them. But when it comes to heavy music, there is not enough pressure and audacity. And overdriven guitars fall into the overall mix a little. The low frequencies of Devialet Gemini have sufficient density, elasticity, depth and are accentuated just a little. Sub-bass is not very much, but enough to create the desired “substrate”. On the other hand, bassheads may not find it enough. Lows are well controlled and sound natural, well emphasizing the character of the instruments. The mids are very well developed, lively and natural. Without going into super-detail, but with the necessary emotional coloring, conveying the character and timbre of the instruments. The imaginary stage is quite good, both in width and depth, with a decent separation of instruments. Especially given the form factor of the model. The high-frequency part of the range is transparent, with good elaboration, but without busting: with no sources or materials, high frequencies do not cut on the ears, at the same time they add volume, space and the necessary emotionality. The only thing worth mentioning is the low headphone volume margin. Some may not have enough.

Active noise cancellation works very wellespecially in combination with passive soundproofing with the right fit and good selection of nozzles. The top-end Sony WF-1000XM4 in terms of noise reduction almost fall short, but overall very good. The quality of voice transmission, given the form factor, can also be assessed as good: the interlocutor clearly hears information even if you are on the street. The voice sounds relatively natural, although the overall frequency range is, of course, cut down.

What about autonomy?


</ img>

Devialet promises that Gemini is able to work up to4 hours in noise canceling mode and up to 6 hours without it. And the case allows you to charge the headphones four times. In reality, the headphones were used at high volume with noise cancellation. Batteries last approximately 3.5 hours, maybe a little less. Far from a record figure, although in most cases this will be enough. Of the useful and convenient features, it is worth noting the support for Qi wireless charging.
