Berlin – September 10, 2026 -- DUVA, a brand created by Fitnexa, unveiled its DUVA ONE sleep earbuds at IFA Berlin 2026, with a planned launch in October 2026 at a target retail price of $349.99.
Unlike wearables that only analyze sleep after waking, DUVA ONE is built to respond during the night itself. The system pairs low-profile in-ear buds with a sensing charging case and a companion app to detect changes in the sleeper and the bedroom, then adjust sound and noise control accordingly.
