Ozlo, the sleep earbuds startup from former Bose engineers, is launching its next device. On Tuesday, the company unveiled Sleepbuds 2, an updated version of its original product that tackles key areas of improvement, including battery life, connectivity, and sound quality. The new model costs $279, a 12% increase from its predecessor.

The launch marks Ozlo’s first major update since the release of its original device and reflects the company’s evolution from a continuation of Bose’s brand into its own sleep platform.

The original Sleepbuds, launched in late 2024, were meant to fill the hole left by Bose’s departure from the category the year prior. Ozlo’s co-founders, N.B. Patil, Brian Mulcahey, and Charlie Taylor, were Bose veterans who had been deeply involved with the Sleepbuds program and saw the potential to continue the business. They acquired and licensed the Sleepbuds research and IP for their new company, Ozlo, making its first product essentially a continuation of Bose’s earlier efforts.

The initial earbuds, which now have more than 200,000 customers, were smaller and more low-profile than AirPods. This made them more comfortable to wear at night, especially for side sleepers. They also offered built-in sleep sounds, Bluetooth streaming, passive noise blocking, an in-ear alarm, sleep tracking, and other features.
