DEVIALET Gemini II Deep Forest

The DEVIALET Gemini II Deep Forest wireless headphones with a closed-back design deliver an exceptional listening experience with adaptive noise cancelling technology. They connect to your sound source via Bluetooth 5.2 wireless technology with support for AAC, aptX and SBC codecs. The built-in battery offers up to 22 hours of listening time, with charging handled by the included case. Their IPX4-rated construction resists water splashes during sports. The integrated directional microphone makes it easy to handle phone calls.

Sound and Tuning

The 10mm drivers operate within a frequency range of 5Hz to 20,000Hz. The headphones have a sensitivity of 120dB/mW with an impedance of 32 Ohms. Audio transmission uses AAC, aptX, and SBC codecs to preserve the detail of the recording. They ensure accurate reproduction of both bass and treble frequencies across various devices, with the system comprising two headphones for stereo listening.

Noise Cancelling and Transparency Mode

Adaptive noise cancelling dampens unwanted ambient sounds. If needed, you can activate the ambient sound feature, which lets sounds from your surroundings pass through directly to your ears. This setting facilitates safe movement in city traffic without needing to remove the headphones. Switching between modes is easily done directly on the body of the headphones.

Battery Life and Charging

The headphones themselves last for 5 hours on a single charge. By using the case, the total operating time is extended to 22 hours, which corresponds to the battery life. To recharge, you can use wireless charging or a USB cable connected to the case. The battery charging process takes place directly in the case, which reliably prepares both headphones for many more hours of listening.

Calls and Microphone

The integrated microphone uses directional sensing to accurately capture your voice. The system includes features for noise and echo cancellation during calls. You can handle phone calls without needing to take your mobile phone out of your pocket. Calls can be conveniently answered by pressing the control button directly on the earbud, which also supports a voice assistant.

Comfort, Fit, and Durability

The IPX4-rated construction resists splashes of water and sweat during exercise. The closed-back earbuds fit securely in the ears and are suitable for running or other sports activities. The package includes interchangeable ear tips in various sizes for an optimal fit. Their low weight of 61g contributes to comfortable all-day wear.
