2. Design and packaging

– Devialet Gemini comes with one charging box, 1 USB-C cord, 1 set of Eartips, and related papers.

– Sliding headphone box

– The headset is long but not thick; wearing it in the ear is less discomfortable.

The outer shell of the headset is made of polymer material coated with a soft matte layer to hug the ear canal when worn. The back of the earbud is rounded and printed with a rather luxurious logo. That is also the touch control surface for operations when listening to music.

Each earbud weighs only about 8g, so it is very comfortable to wear on the ear and is extremely suitable for sports training. IPX4 waterproof certification also helps the headset withstand light splashes or sweat, but it isn’t easy to survive if immersed in water.

3. Eartip has many sizes

The headset has a clip-on design that is easy to wear, comes with a set of XS / S / M / L ear tips suitable for most ear sizes. Eartips, in general, have good sound insulation when worn for a long time so that you can listen to music without opening the ANC noise canceling to save battery if needed, especially when the surroundings are not too noisy.

When you want to focus on work or enjoy music in the remaining cases, Devialet Gemini’s ANC noise cancellation quality is very good. It can cancel most of the ambient noise at High and Plane levels.

4. Devialet Gemini’s special technologies

Each earbud is equipped with a 10mm driver with a nominal frequency response of 5Hz-20kHz. Gemini owns Devialet’s exclusive dual-chamber design that has been used in high-end models, so you can be completely assured of its sound quality, in addition to Devialet Ear Active Matching technology for listening. Self-measured listening and customizing the audio signal best suit the wearer’s ear structure, thereby providing a one-of-a-kind listening experience.

The logo on the back of Devialet Gemini is also the touch control surface. Touch operations are detected quite sensitively and accurately, including basic controls such as playing music, stopping music, skipping songs, activating ANC noise cancellation, and opening Transparency Mode. Users can also add separate controls using the app on iOS and Android.

5. Noise-canceling performance

Devialet Gemini is equipped with two noise-canceling microphones and digital filters to analyze and eliminate ambient noise effectively. Internal Delay Compensation technology enhances noise cancellation performance with ultra-wideband. Allows customizing the noise cancellation level in 3 modes Low, High, and Plane (only when traveling by plane). Enabling ANC noise cancellation will slightly boost the bass and make the soundstage feel a bit narrower. However, in general, it still retains the necessary fidelity when listening to music.

Transparency Mode will allow you to quickly hear the person’s voice next to you and still cancel the surrounding noise partially. This mode is extremely useful when you need to listen to announcements in public or chat with people around. Transparency Mode also has two modes from low to high for you to choose.

6. Devialet Gemini Headphones Battery Life

The introduced headphones will have a battery life of 6 hours when noise canceling is on and 8 hours when noise canceling is off; the charging case adds another 16 hours, equivalent to 24 hours of use from full to empty. In actual use, I have to open the volume of Gemini to about 80-85% to hear it, so the actual battery when turning on noise cancellation and listening to music reaches ~ 5.5h, which is also too good.

The charging case using a USB-C port is also an advantage for today; Gemini also supports Qi wireless charging.

7. Other Features

In addition to a dedicated microphone for noise cancellation, Devialet Gemini also has a conversational microphone with very commendable quality, especially in environments with moderate noise levels; for example, when I sit in the office, the voice is loud and loud. My friend on the other end of the line said that my voice is warm and full, but when I ride my bike home, my voice when talking with Gemini will lose its thickness due to a lot of wind on the street and many vehicles, so this is Unavoidable.

The headset will automatically adjust the appropriate noise cancellation level for the clearest sound when receiving a call. Gemini’s microphone can also call the virtual assistant to perform standard commands, supporting Siri and Google Assistant.

8. Connection quality

Devialet Gemini has equipped with Bluetooth 5.0 technology that supports AAC, SBC, and aptX codecs for stable connectivity within a range of about 10m. The connection speed with other devices is also very fast, so you can listen to music right away without going through cumbersome steps.

9. Sound

Gemini has a bright sound, wide space, high mid and treble, although not harsh but sharp and strong, the midrange is slightly back, the bass is fast, rich, firm, compact, detailed low-bass, deep down. If you are a fan of EDM, Pop, City Pop, Classical, Gemini is reasonable.

Bass is a strength of Devialet Gemini. The upper bass is around and fast, very good force, but the upper bass is quite accurate, not much. The sub-bass part is deep, solid, clear, slightly strong bass listening to Lost Frequencies; Daft Punk gives a definitive feeling, no sound comes out. In my opinion, this bass is better for rock music than Momentum True Wireless 2.

And here are some tips to make it easier for you to control your Gemini headset:

Enable Pairing mode to connect to a new device:

– Slide open the cover of the charging case

– Put both ears in the box

– Hold down the button on the bottom edge of the charging case for about 3 seconds until the blue signal light flashes

– Open the Bluetooth settings on the phone and connect to the headset named “Devialet Gemini.”
