The Sleep System That Understands You Best.
BERLIN, Sept. 6, 2026 /PRNewswire/ -- DUVA, created by Fitnexa, is introducing DUVA ONE at IFA Berlin 2026. This intelligent in-ear sleep system is designed to sense changes in the user and the bedroom, then personalize audio, noise control, and device behavior throughout the night.
Most sleep wearables explain what happened after users wake up. DUVA ONE is designed to help while the night is still happening. Its low-profile earbuds, environment-sensing charging case, and app work together to determine when and how to respond.
A user might start the night with a podcast over Bluetooth. After they fall asleep, DUVA ONE can introduce locally stored sleep audio and optimize power use. If a partner begins snoring or traffic grows louder, it can adjust ANC or add sound masking. In the morning, a private offline alarm wakes only the wearer, without requiring an active phone connection.
In-ear PPG and motion sensors estimate sleep stages and track heart rate, HRV, sleep position, and movement, while the case monitors noise, light, temperature, and humidity. The AI Agent interprets these signals alongside playback status and personal preferences to select an appropriate response. Users control sleep audio, playback duration, ANC strategy, and nighttime interventions in the DUVA App.
"Sleep does not happen in a static environment, so sleep technology should not remain static either," said Diego, Founder of Fitnexa. "DUVA ONE is designed to respond while sleep is still happening."
Key Highlights- Layered noise relief: Passive isolation, Hybrid ANC, and sleep audio provide noise reduction of up to 42 dB, 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 gradually fall asleep.
- Side-sleeping comfort: Each fitted earbud weighs approximately 3.3 grams and has an approximately 9.9 mm low-profile design. Two ear-tip shapes and multiple tip and stabilizing-wing sizes provide more than 40 fit configurations.
- 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 planned for release in October 2026 at a target retail price of US$349.99, with target markets including the United States, Canada, the United Kingdom, the European Union, and Australia.
