A startup founded by former Bose engineers is redefining the sleep audio market with its second-generation earbuds. Ozlo unveiled the Sleepbuds 2 on Tuesday, addressing battery life, connectivity, and sound quality complaints from the original model. Main Developments Priced at $279—a $30 increase from the original's $249—the Sleepbuds 2 represents Ozlo's first major hardware update since launching in late 2024. The company improved core features without abandoning the original design philosophy. Background Ozlo emerged from Bose's 2022 decision to exit the sleep earbuds category. Co-founders N.B. Patil, Brian Mulcahey, and Charlie Taylor had led Bose's Sleepbuds program and saw an opportunity to continue the work. They acquired and licensed the Sleepbuds research and intellectual property, making the original Ozlo Sleepbuds essentially a direct continuation of Bose's abandoned effort.

The price increase signals confidence in the standalone brand, while the focus on battery and connectivity addresses the most common barriers to adoption in the sleep audio niche. What's Next Ozlo will likely face pressure to prove its product roadmap extends beyond incremental updates. The company's ability to attract new users—not just former Bose customers—will determine whether this second device cements its place as a sleep-tech leader.
