Fitnexa’s sleep‑wearable DUVA ONE debuted at IFA Berlin, offering real‑time audio personalization and adaptive noise control during sleep.

Fitnexa unveiled its latest sleep‑wearable, DUVA ONE, at IFA 2026 in Berlin, promising real‑time audio personalization and adaptive noise control that adjusts to the wearer’s sleep stages.

What Sets DUDU ONE Apart

The earbuds combine built-in sensors with AI‑driven algorithms to monitor heart rate, movement and ambient sound, then automatically tailor soothing soundscapes or silence disruptive noises.

Unlike traditional sleep headphones, DUVA ONE’s responsive audio engine can shift from white noise to gentle music within seconds, matching the user’s physiological cues.

Key Features

  • Integrated biometric sensors for heart‑rate and motion detection
  • Adaptive noise cancellation that reacts to sudden sounds
  • Customizable sound libraries accessible via the DUVA app
  • Up to 10 hours of playback on a single charge

Design and Comfort

The earbuds feature a low‑profile, silicone‑coated design intended to stay securely in place without causing discomfort during prolonged wear.

Fitnexa also highlighted a companion pillow‑compatible strap that lets users position the device just behind the ear for a hands‑free experience.

Availability and Pricing

DUVA ONE will launch in select European markets later this year, with a suggested retail price of €199. Early adopters can pre‑order through the official website.
