Devialet Gemini II In-Ear Wireless ANC Headphones

(IM)PERMEABLE SOUND

You can’t be in two mindsets at once. Or can you? With second-generation Devialet Gemini II True Wireless earbuds, your feet may be on the ground, but your mind is in another world. Fifteen years of acoustics R&D and engineering have been condensed into an even smaller and more ergonomic design that brings you the best of sound in all its dimensions. A new custom titanium-coated driver, Qualcomm® aptXTM codec, Devialet Adaptive Noise CancellationTM, Bluetooth 5.2 with multipoint, enhanced user experience and connectivity are just the beginning.

Second generation. Second to none.

DEVIALET GEMINI II packs a suite of enhanced innovations to take the listener even
deeper into pure unaltered sound: a brand-new custom 10 mm Devialet titanium-coated
driver and Qualcomm® aptXTM codec offer an even deeper acoustic experience and with the new patented Active Wind Reduction (AWR®) technology, the earbuds will actively reduce wind noise to reinforce the user immersion automatically and in any environment. Voice calls have also been completely redesigned to encompass an advanced voice pick-up algorithm along with a built-in modern bone conduction sensor.

With DEVIALET GEMINI II, the user is protected from the ambient chaos and transported
to a place that’s harmonious and pure. Our new Devialet Adaptive Noise CancellationTM
technology dynamically adjusts to the shape of the ear to reduce any audio artifacts and
white noise. A hybrid dual-microphone structure teams up with digital filters using proprietary Internal Delay Compensation (IDC®) technology to improve both the level of active noise reduction and its effective bandwidth even further. Enjoying music at its finest is easier with Devialet Gemini's Bluetooth 5.2 connectivity with multipoint connection and auto switch between two active devices simultaneously.

On the design front, the reimagined second-generation earbuds boast the same soft touch and iconic shape, but in a more compact, sleek, and versatile design. Their curvature has been optimized to fit any ear, and improved microphones are more seamlessly encapsulated inside the earbud. The charging case now features a flip top for instant access and is 40% smaller to fit easily inside any pocket.

PURE SOUND. PURELY INSEPARABLE.

Next-generation earbuds, next-level sound. Devialet Gemini II packs a suite of enhanced tech to take you even deeper into pure sound: a brand-new custom 10 mm Devialet titanium-coated driver and Qualcomm® aptXTM codec offer an even deeper acoustic experience. With the new Active Wind Reduction (AWR®) technology, your earbuds
will actively reduce wind noise. This is uncompromised listening.

Custom 10mm Titanium coated driver.

DEVIALET GEMINI II embeds a customized loudspeaker specifically chosen to
complement the electroacoustic and mechanical characteristics of the earbuds.
The 10 mm diameter driver unit, wider than the average of the competitors, allows the
earbuds to provide rich and powerful bass down to 5 Hz, melodic mid-range, 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 ultra-precise noise cancellation signals. The unit uses a high-field neodymium
magnet, providing excellent sensitivity.

Qualcomm® aptXTM codec: high-fidelity audio and low latency connectivity

DEVIALET GEMINI II features Qualcomm® aptXTM 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 synchronisation.

Wind noise reduction with AWR®.

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 the user experience. On the mechanical side, both external microphones are tightly cradled in a protective layer of high impedance anti-wind 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.

Each external mic is hidden in behind a layer of high impedance anti-wind material, and a cavity protects the microphone membrane from any wind blowing on the surface of the earbud.

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

With Devialet Gemini II, you're protected from the ambient chaos and
transported to a place that’s harmonious and pure. Our new Devialet Adaptive Noise CancellationTM technology dynamically adjusts to the shape of your ear. The result? Reduction in audio artifact, reduction in white noise and a more pleasant listening experience with zero compromise on performance. Additionally, a hybrid dual-microphone structure teams up with digital filters using our proprietary Internal Delay
Compensation (IDC®) technology to improve both the level of active noise reduction and its effective bandwidth even further.

Internal Delay Compensation (IDC®).

In practice, conventional ANC systems are less efficient on middle and high frequencies (generally from 1.5 kHz upwards). The higher the frequency, the greater the delay in reduction in the higher frequencies. Therefore, a phase shift in the system can be observed. Additionally, the strong directionality of the higher frequencies are more difficult to cancel than the less directional low frequencies. 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 anti-noise 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.
