About
Ozlo Sleepbuds are purpose-built sleep earbuds that combine advanced noise-masking hardware with a smart companion app to transform any environment into a sleep sanctuary. Unlike general-purpose earbuds, every design decision—from the ultra-low-profile shape to the soft ear-tip materials—prioritizes all-night wearing comfort, even for side sleepers. The earbuds use passive noise-blocking combined with soothing audio streams (nature sounds, white noise, and more) to mask disruptive sounds like snoring, traffic, and urban noise. With up to 10 hours of continuous battery life, they last through even long sleep cycles without needing a recharge mid-night. The Ozlo App pairs with the buds to surface personalized sleep-pattern insights, letting users understand how sound and environment affect their rest. Users can customize their audio experience, review nightly data, and refine their sleep routine over time. Ozlo Sleepbuds are backed by a medical advisory board that includes sleep neurologists and scientists from institutions like Brigham and Women's Hospital. They are HSA/FSA approved, come with a 1-year warranty, free shipping, and a 30-day money-back guarantee, making them accessible for anyone serious about improving sleep quality, recovery, mood, and daytime cognitive performance.
