In the era of the popularity of true wireless earphones, no matter walking on the road or entering the room, almost people "ear" a pair of true wireless earphones. Of course, due to the large market demand, more and more acoustic brands are attracted to invest in true wireless earphones. In the development and manufacture of wireless earphones, DEVIALET, an acoustic brand from France, recently officially launched its first true wireless earphone Gemini in Taiwan. In addition to the main top-notch sound quality and active noise reduction technology, it also has three exclusive brand-new acoustic patents: PBA pressure balance structure, IDC internal delay compensation, and EAM audio active pairing core technology, users can also use the dedicated Devialet Gemini app to set more noise reduction and transparency modes, and enrich the listening experience of headphones .

Devialet Gemini's outer box packaging BC547AZL1 adopts a black-based color matching design. There are photos of the headphone body and the charging box on the outer box. The three core technologies of the brand mentioned above are printed on the back of the outer box, including the ANC active drop After noise, the maximum continuous music listening time is about 6 hours, IPX4 waterproof level, support for Qualcomm aptX decoder and Bluetooth 5.0 wireless transmission technology and other simple specifications, in addition, Devialet Gemini also provides a 2-year global warranty in Taiwan.

The design of the inner box packaging is quite neat and simple, including the charging box with the headphone body, the USB-C charging cable and the sealed earplugs of three sizes. In addition, the instruction manual and safety manual are also included in the inner box packaging.

Although Devialet Gemini's storage and charging box is made of reinforced plastic material, it creates a high-quality visual sense through the fog black coating. The upper cover of the charging box adopts a sliding-type opening and closing design, and the shape design is similar to the earphone. The main body forms a style that echoes inside and outside. There are four metal contacts on the earphone charging slot in the charging box, which adopts the mainstream magnetic suction design.

The size of Devialet Gemini's storage and charging box is slightly larger, but it is not as large as the charging box that was previously tested for Bose QC Earbuds true wireless noise-cancelling headphones. There is a Bluetooth pairing button on the front of the charging box, and a power indicator on the top. There is a USB-C charging port configuration, and the front end of the upper cover of the outer box has anti-slip particles for easy sliding of the upper cover.

The Devialet Gemini headphone design is inspired by the side panel design of our classic Phantom audio series, the panel with the brand Logo on the outside of the case is a touch panel configuration, the upper and inner rear of the headphones are equipped with independent internal and external microphones, and a can enhance The microphone for voice transmission, the headset also has a wearing sensor and a metal charging contact inside. Devialet Gemini uses a short tube design, which will not have a strong sense of intrusion when wearing it. The way to disassemble and install the earplugs is simple, and it is easy to clean up.

The Bluetooth pairing method of Devialet Gemini true wireless earphones, as long as you slide the top cover open and long press the Bluetooth pairing button, you can find the earphones on the Bluetooth list of the device to connect. It is recommended that you also go to Google Play and Apple App Store Download the dedicated app to use with the headset. Devialet Gemini, which uses Bluetooth 5.0 wireless transmission technology, has a very good performance in Bluetooth connection stability. I tested it near a MRT station with a complex wireless environment, and there was no disconnection. This true wireless headset also It supports a single headset to be used alone. If you want to use it as a call headset when driving, there is no big problem.

In the exclusive Devialet Gemini app of the same name, users can check the remaining power of the left and right earphones. There are three ambient sound modes: noise reduction, normal and transparent at the bottom of the main screen. Especially in the noise reduction mode, there are a total of There are three modes of low, high and aircraft to choose from. As for the transparent mode, there are also two modes of high and low. I will introduce the listening experience of each mode for you below. In the settings menu on the right, there are double-tap operation settings, automatic pause function on and off, and settings including Custom, Preset, News/Podcast, Bass, Treble, Dynamic, and Mid Bass. Select the sound mode, and finally you can see whether the earplugs have a check function for correct wearing.

On the whole, Devialet Gemini's dedicated app is actually quite complete. It is not difficult to see that although this product is its first true wireless earphone, there has been a lot of painstaking efforts in the overall planning of the product, which also makes the use of Users can have a better experience when using it, and this part is fully worthy of recognition.

Devialet Gemini adopts the wearing method of earplugs. After putting the earphones in, it needs to be rotated to the ear socket. It is a small skill to wear. It can increase the stability when wearing. The design of the short tube greatly reduces the sense of intrusion when wearing, and the arc-shaped case with skin-friendly layer and lightweight earphone design will not have too obvious pressure when wearing. Wearing comfort is also remarkable. Due to the IPX4 dust and water resistance rating, I will also wear this headset for sports, including jogging, heavy training and cycling, etc. Basically, in the sports mode with large movements, the wearing stability of the headset is quite sufficient. , If it rains or sweats, it is recommended to clean with a wet paper towel and a dry cloth.

The touch operation of the left and right earphones is quite sensitive. Basically, it can be operated after a light touch without the discomfort of plugging the earphones into the net. However, it is relatively easy to set the personalized operation function only for the double-click operation. Unfortunately, it is recommended that more personalized touch operation options can be turned on later.

Devialet Gemini has ANC active noise reduction technology and can be matched with a dedicated App. There are three noise reduction modes, normal mode and two transparent modes (that is, transparent modes) that can be adjusted. Let’s share three noise reduction modes first. In the "low" noise reduction mode, it can isolate most of the low-frequency ambient noise, but retain the complete human voice or keyboard percussion sound, but in this noise reduction mode, there will be more uncomfortable noise. Negative pressure, you need to play music to reduce the negative pressure, the volume can be set at 45~50%.

As for the "high" noise reduction mode, there will be no negative pressure. It also isolates low-frequency ambient noise, but the human voice is still clearly audible. The last "airplane" noise reduction mode, because it is impossible to take a plane to go abroad now, Therefore, there is no way to take a plane. I will turn it on when I take the MRT or bus, but I feel that it is similar to the high noise reduction mode. I guess this mode should be the same as the atmospheric pressure of the Sony WF series true wireless noise canceling headphones. The optimization is the same, except that it cannot be detected by the user through the application.

In normal mode, the headset will also have a slight negative pressure. If it is matched with suitable earplugs, it will have a passive noise reduction effect of about 70~80%. When the music playback volume is at 45~50%, it can enter about Up to 90% sound isolation, you can still hear human voices and high-frequency sounds. The last transparent mode is the transparent mode that is generally used. There are two modes: “low” and “high”. The difference lies in the acceptance of the external ambient sound. In the low transparent mode, you can hear the human voice and the high audio frequency in the environment. In the high-transparency mode, you can also hear low-frequency ambient sounds, such as the continuous operation of the electric fan, etc. You can switch according to the environment and usage needs.

In the listening experience part, I also maintain the listening device configuration of my daily life, use the iPhone 13 Pro to play music from Apple Music, and use the preset (average) equalizer mode for audition. Devialet Gemini belongs to the back of the vocals. The sound quality setting is also fully in line with the general user's sense of hearing. Although the high-frequency part is clear, it is not Slightly dull, it will be slightly insufficient for the interpretation of the high position of the violin or the high key position of the piano. Although the treble can be enhanced through the application, this style is presented in the basic listening performance.

Devialet Gemini features an exclusive Hearing Active Pairing (EAM) algorithm that captures the listener's specific ear shape in real time and automatically adjusts the signal entering the ear up to 10,000 times per second for a fully immersive and comfortable listening experience. In the actual listening experience, it is not difficult to find that in the noise reduction, normal or transparent mode, there is no obvious difference in sound quality, and the resolution of the sound also maintains a very good performance, and the interpretation of each instrument and vocals is quite similar. There is a level, and what Brian likes most is that the sense of space and positioning of this headset is quite good. It is suitable for playing live concerts, operas or symphonies and other music, and can feel the vast sense of space.

This Devialet Gemini true wireless noise-cancelling earphone from France has a comfortable and stable wearing experience, plus IPX4 dustproof and water-repellent rating, it can be used whether it is commuting to work, indoor work or outdoor sports, the actual use level is considered Quite rich, I myself turned on the "high" noise reduction mode, with 50% of the music playback volume environment, the single use time is about 5 hours and 46 minutes, and the remaining power performance is less than 10%, the battery life performance is not bad Moderate.

Devialet Gemini also has three noise reduction modes, two transparent modes and general modes. Although in the noise reduction mode, there will still be a negative pressure, but in actual use, it can also cope with different use environments, and in three different In the mode, there is not much difference in sound quality performance, and you can get a sound quality experience above the level in any environment. On the whole, Devialet Gemini is not cheap for its first true wireless noise-cancelling headphones. The planning of headphones, charging boxes and apps are quite complete, so that consumers can get started immediately after purchasing, but this one Devialet Gemini from France is also priced at 10,990 yuan, and the starting price is high. If you want to buy it, you can try it on and listen to it, so as to know whether it is worth starting with the boutique price.
