Ozlo updates sleep earbuds with longer battery life and new features
Ozlo says its new Sleepbuds 2 last up to 14 hours, but buyers are still being asked to trust a Bose-era category that Bose itself abandoned.
Ozlo has rolled out Sleepbuds 2 with up to 14 hours of battery life, a Smart Case that adds another 2 to 3 charges, and a redesign the company says is built for all-night comfort. The startup is also leaning on improved connectivity, a 30-day return policy and a 2-year warranty as it tries to convince buyers that sleep earbuds can outlast the problems that helped kill the category.
The update arrives after Bose discontinued Sleepbuds in 2023 and later said its Sleep app would no longer be available for download after July 21, 2025. Ozlo, founded by three former Bose employees, has built its pitch around carrying that concept forward, and its comparison pages position the new earbuds directly against Bose Sleepbuds I and II. Ozlo has also offered a discount to former Bose Sleepbuds users, a sign that the company knows this market still lives on customer frustration as much as on new features.
That legacy matters because the original Bose Sleepbuds II, launched in September 2020, were designed around noise masking and relaxation content rather than open-ended music playback. Ozlo’s materials keep that same sleep-first frame, describing noise-masking technology, science-backed sleep sounds and sleep insights and patterns. A related Ozlo page says some configurations support Bluetooth LE streaming for up to 10 hours, widening the product beyond the limited audio model Bose used, but also raising the question of whether more features make the earbuds better sleepers or simply more capable gadgets.
Outside recognition has helped Ozlo make its case. Time included Ozlo Sleepbuds in its Best Inventions of 2025 list, and the Consumer Technology Association named the product a CES 2025 Innovation Awards Honoree in headphones and personal audio. Reviewers have also cited a $349 price tag, while Mashable said the newer Sleepbuds 2 arrived with better battery life and a lower price point than the predecessor. Ozlo is now selling the earbuds through regional storefronts in the United States, United Kingdom, Canada, Europe, Australia and New Zealand, pushing a niche product once abandoned by Bose into a broader global sales pitch.
