DUVA Launches DUVA ONE: Personalized Sleep Earbuds at IFA 2026

DUVA, developed by Fitnexa, unveiled its new sleep innovation, DUVA ONE, at the IFA Berlin 2026. Unlike traditional wearables that analyze post-sleep data, DUVA ONE acts during sleep. The in-ear system adapts audio, noise control, and behavior throughout the night, responding to the user's surroundings.

DUVA ONE's technology includes low-profile earbuds and an app-driven charging case, capable of adjusting to environmental changes like snoring or increased noise through active noise cancellation (ANC) or sound masking. Moreover, it detects sleep stages and tracks vital metrics, employing its AI to personalize user experiences.

Key features include up to 16-hour battery life, lightweight design for comfort, and data privacy measures. DUVA ONE will be available in October 2026, priced at $349.99 across major markets, including the US and Europe.
