Ozlo launches Sleepbuds 2 with longer battery life and improved comfort

Ozlo, a startup founded by former Bose engineers, unveiled the Sleepbuds 2, a dedicated sleep‑focused earbud priced at $279. The new model offers up to 14 hours of playback on a single charge and a smart charging case that can power the buds for two to three nights. It features a smaller, low‑profile design intended to stay in place for side sleepers, softer ear‑tips for added comfort, and a redesigned antenna for more reliable Bluetooth connectivity.

Additional upgrades include an amplified audio system with personalized sound modes, a Sleep Shield that blocks calls, alerts and notifications, and five customizable sleep modes that automatically switch streaming audio to built‑in sleep sounds when sleep is detected. The product builds on the original Ozlo Sleepbuds launched in late 2024, which already had more than 200,000 customers and filled the gap left by Bose’s exit from the sleep‑earbud market.
