Devialet Gemini II Overview

From Manufacturer

Benefiting from 15 years of acoustics R&D and engineering, the Devialet Gemini II True Wireless Earbuds deliver state-of-the-art noise cancellation technology, highly effective Active Wind Reduction, and potent 10mm titanium-coated drivers for the best possible listening experience no matter where you are. With Transparency Mode, you'll never lose awareness of your surroundings, and thanks to the built-in Bluetooth 5.2 technology, you'll never lose connections to your devices either, with multipoint support for up to two devices and convenient compatibility with Google Fast Pair and iOS App Match.

Intuitive touch gesture control makes it absolutely painless to execute a number of control functions, such as engaging in hands-free phone calls or switching modes. With the Devialet Gemini app, you can customize touch controls and dive even deeper into your custom listening experience. IPX4 rain and sweat resistance keeps your earbuds safe and functional during inclement weather or heart-pumping workouts. And with the handy Qi wireless-compatible charging case, you can get a maximum of 22 hours of playback for the longest journeys and commutes. The Devialet Gemini II includes four pairs of silicone eartips and a USB-C charging cable for the case.

Pure Sound, Purely Inseparable
Devialet Gemini II embeds a customized loudspeaker specifically chosen to complement the electroacoustic and mechanical characteristics of the earbuds. The 10mm diameter driver unit, wider than the average of the competitors, allows the earbuds to provide rich and powerful bass down to 5 Hz, melodic midrange, and crystal-clear treble up to 20 kHz. All of this while maintaining excellent linearity and power sensitivity. The inclusion of titanium coating to top the three layers of polymers, as well as a signature neodymium magnet, substantially optimize the earbuds' stiffness and help generate ultraprecise noise-cancellation signals. The unit uses a high-field neodymium magnet, providing excellent sensitivity.
High-Fidelity Audio, Low-Latency Connectivity
The Devialet Gemini II features Qualcomm aptX codec, the state-of-the-art audio coding technology designed to enhance Bluetooth wireless sound quality. Whether the users are tuning into their favorite track or gaming with friends, they will benefit from seamless synchronization. You also get support for standard AAC and SBC formats as well.
AWR: Active Wind Reduction
Devialet Gemini II also features AWR (Active Wind Reduction), a proprietary solution that uniquely blends mechanical and design innovation with software algorithms to greatly limit the impact wind has on your listening. On the mechanical side, both external microphones are tightly cradled in a protective layer of high-impedance antiwind mesh material to limit the impact of wind on the microphones membranes.

Additionally, the microphones are hidden behind a cavity to protect them from the wind blowing and turbulence that can form on the surface of the earbuds. On the software front, the teams have built a precise wind-detector program, using the microphones as input and real-time digital processing to smartly control the intensity of the Transparency gain to limit the presence of wind noise inside the signal.

Devialet Adaptive Noise Cancellation
The new Devialet Adaptive Noise Cancellation dynamically adjusts to the shape of your ear, which greatly reduces audio artifacts and white noise to allow for a pleasant listening experience with zero compromise on reduction level and bandwidth effectiveness. The Devialet Gemini II noise-cancelling system relies on a hybrid dual-microphone structure coupled with digital filters using proprietary Internal Delay Compensation (IDC) technology to improve both the level of active noise reduction and extend its intensity in the higher frequencies.
IDC: Internal Delay Compensation
IDC is a proprietary signal processing system that allows for the precise adaptation of noise processing filters by anticipating the natural limitations of an ANC system. Sound signal processing is performed digitally in the frequency domain.

The IDC algorithm acts directly on the transfer function of the antinoise filter. It ensures that its response is optimized to extend the range of action of the filter to extend its action band from the infrasonic bass to the midrange.

Transparency Mode
Thanks to the transparency mode, the listener can enjoy the best of sound while staying in tune with the surrounding world. The external environment and dialogues become permeable for better interaction with the user's surroundings. Based on the same hybrid structure as Devialet Adaptive Noise Reduction, the transparency mode uses the two microphones of the ANC system to allow users to actively hear external sound as naturally as possible.
Supreme Ergonomics
Four distinct eartip sizes (XS, S, M, L) ensure an optimal fit and a sensation of lightness making Devialet Gemini II earbuds more versatile and comfortable. The all-in-one touch button at the top of the earbuds makes it easier to use and more customizable, letting you select which gesture will switch on the Devialet Adaptive Noise Cancellation, activate your voice assistant, play/pause music, and more.
Resilient Design
Devialet Gemini II's IPX4 rating guarantees resistance to sweat and water splashes, providing additional support when exercising. A new protective grid at the end of silicone eartips combined with a foam component integrated into the earbud tube prevent any foreign substance (dust, debris) from entering the earbuds. If damaged over time, both components can be cleaned and/or replaced, maximizing Devialet Gemini II's longevity.
Bluetooth 5.2 with Multipoint Support
These earbuds supports Bluetooth 5.2 wireless connectivity enabling the signal to remain clear and stable within a 44' radius. The second-generation earbuds also offer multipoint connection and autoswitch. In other words, the user can connect their earbuds with up to two devices at once and the earbuds will intelligently switch devices. This way, the user could listen to music on their laptop and take an incoming call on their phone seamlessly.
Devialet Gemini App
The Devialet Gemini App offers the ability to:

  • Navigate between the ANC and Transparency modes
  • Access battery levels directly from the home screen
  • Control a customizable 6-band EQ, which lets you amplify or attenuate sounds between 6 and -6 dB in 0.5 dB steps
  • Select 6 preselected EQ settings including Bass, Mid, Treble, and Podcast mode
  • Configure touch controls
  • Deactivate Smart pause
  • Control the multipoint automatic connection function
A Refined User Experience with Fast Pairing
Devialet Gemini II is now compatible with Google Fast Pair, which greatly simplifies the Bluetooth connection and pairing process. The cutting-edge Google protocol enables Android users to seamlessly set up their earbuds with a single tap without having to fumble through the Bluetooth settings.

It also offers to download the Devialet Gemini App from the Play Store. The second-generation earbuds also come with iOS App Match, offering iOS users a way to download the Devialet Gemini App directly via a pop-in, without having to search for the app in the App Store.

Devialet Gemini II Reviews

The best, but still flawed

By Brad
Rated 4 out of 5
Date: 2024-05-21

Best microphone quality, miles ahead of Bose QC Earbuds 2, Apple AirPods Pro, and Sony WF-1000XM4 (I've owned each of those). The first earbuds that actually sound clear and unaffected by reasonable amounts of wind or ambient noise. Gemini 2 is worth it for this aspect alone. Check Rtings.com for their recording demo that you can compare between headphones. Best sound quality I've heard from wire-free earbuds. Almost perfectly follows the Harman target HRTF frequency response curve, but with a slight bass boost. I prefer setting -5dB at 80Hz and -1.5dB at 120Hz in the 6-band graphic EQ of the Devialet Gemini app, to get closer to perfectly neutral. Active noise cancelling is as good as the best: about the same as QC Earbuds 2, EXCEPT Gemini 2 has almost NO noticeable self-noise. Meanwhile QC generates a significant amount of white noise by itself. In terms of dB reduction, Gemini 2 wins in some frequencies, while Bose wins in some others. Pretty comfortable but not perfect. Much less ear canal pressure than WF-1000XM4 with foam ear tips. Stays in my ears better than it and AirPods Pro. LESS comfortable than QC Earbuds 2 even though smaller and lighter, because the latter has silicone shark fins that help retention and oblong ear tips. I notice Gemini 2 in my ears more than Bose, and I have to reseat them more frequently. BUG 1: Signal glitches out (suddenly losing one channel for 0.5sec) frequently while using my Sony A7S3 camera's Wi-Fi connection feature within 0.5m away. It also glitched out when cars passed nearby. Bluetooth range is noticeably worse than Bose. This is on firmware 1.3.7, which is latest as of 2024-5-21. BUG 2: Crackle/pop noise when stomping down stairs, jogging, or jumping. Nearly but not quite as bad as WF-1000XM4 or AirPods Pro 1 pre-recall (before October 2020). I believe this is caused by the earbud body bouncing inside the pinna and the lower ANC mic smacking the antihelix. Bose is immune from this because its shark fins stabilize the earbuds.

Hi end sound

I had the previous generation. Compare to it, the Gemini II achieve a more accurate and precise sound which is what I'm looking for when it comes to speakers or headsets. Connectivity works now seamlessly. I recommend these to any real audiophile.
