DUVA ONE Reimagines Sleep Wearables at IFA Berlin 2026

BERLIN, Sept. 6, 2026, DUVA, a brand of Fitnexa, has unveiled its latest innovation, DUVA ONE, at the International Fair for Consumer Electronics (IFA) Berlin 2026. This cutting-edge in-ear sleep system promises to revolutionize the way users experience sleep, offering real-time, personalized adjustments to audio and environmental factors throughout the night.

DUVA ONE is designed to go beyond traditional sleep wearables, which typically provide post-sleep data. Instead, it actively responds to changes in both the user and their bedroom environment. Equipped with low-profile earbuds, an environment-sensing charging case, and a dedicated app, DUVA ONE can adjust audio, noise control, and device behavior based on real-time data.

The system begins with a customizable setup, allowing users to start the night with a podcast over Bluetooth. As the user falls asleep, the earbuds switch to locally stored sleep audio, optimizing power usage. Should a partner's snoring or external noise levels rise, DUVA ONE can adjust active noise cancellation (ANC) or introduce sound masking to ensure a more restful environment.

In the morning, the system features a private offline alarm that wakes the user without requiring an active phone connection. Integrated in-ear photoplethysmography (PPG) and motion sensors track sleep stages, heart rate, heart rate variability, sleep position, and movement, while the environment-sensing charging case monitors noise, light, temperature, and humidity. This data is interpreted by the AI Agent, which selects an appropriate response based on playback status and personal preferences.

Diego, founder of Fitnexa, commented, "Sleep does not happen in a static environment, so sleep technology should not remain static either. DUVA ONE is designed to respond while sleep is still happening."

Key features of DUVA ONE include: - Layered noise relief: Passive isolation, hybrid ANC, and sleep audio provide up to 42 dB of noise reduction with Transparency Mode and adaptive ANC calibration. - Personalized AI sleep guidance: The AI analyzes the user's real-time sleep state and generates personalized audio guidance to help them fall asleep. - Side-sleeping comfort: Each earbud weighs approximately 3.3 grams and features a 9.9 mm low-profile design. Users can choose from two ear-tip shapes and multiple tip and stabilizing-wing sizes to achieve the best fit. - All-night battery: Up to 16 hours in the most power-efficient configuration, including 13 hours of local audio with ANC off and 9.5 hours with ANC on. The USB-C and wireless charging case provides up to five additional recharges. - Private offline alarm: Alarms gradually increase in volume and offer 5, 10, or 15-minute snooze options through the earbud controls. - Privacy-first sensing: DUVA ONE does not record conversations, store ambient audio, or upload raw environmental audio. Users can disable individual sensors and delete historical data.

DUVA ONE is set for release in October 2026 with a target retail price of US$349.99. Target markets include the United States, Canada, the United Kingdom, the European Union, and Australia.
