Ozlo, a startup founded by former Bose engineers, has launched its Sleepbuds 2, an updated version of its sleep-enhancing earbuds. The new model, priced at $279, represents a 12% increase from its predecessor and aims to improve upon key areas such as battery life, Bluetooth connectivity, and sound quality.
The Sleepbuds 2 offer 14 hours of battery life, an upgrade from the original's approximately 10 hours, and the charging case provides power for two to three nights of use. Connectivity issues, a common complaint with the first generation, have been addressed with a redesigned antenna for longer range and more reliable connections. The audio system features a built-in amplifier for better sound masking and personalized tuning options including Spoken Word, Airplane, Focus, and Balanced modes.
New features include a "Sleep Shield" to block calls and notifications, and expanded sleep insights that monitor breathing and movement via the buds, and room conditions like sound, light, and temperature via the case. Ozlo plans to leverage AI to interpret sleep patterns and is developing an AI "sleep buddy" for users to discuss their sleep data.
The original Sleepbuds, launched in late 2024, were developed by Ozlo's co-founders who were instrumental in Bose's previous sleep earbud program. They acquired and licensed the intellectual property from Bose to continue the product line, which has since garnered over 200,000 customers. The initial earbuds were noted for their low-profile design, comfort for side sleepers, built-in sleep sounds, Bluetooth streaming, passive noise blocking, in-ear alarm, and sleep tracking capabilities.
