FAQ's
What is the return policy?

Ozlo Sleepbuds come with a 30-day return policy. See details.

What is the warranty?

Ozlo Sleepbuds come with a 1-year warranty. In the EU and UK, that is extended to two years. See Details

Do they have noise cancelling?

Our Sleepbuds® feature passive noise cancellation to block out snoring and other disruptions. In addition, we offer “noise masking” audio content (think, white noise, ocean waves, babbling brook, etc) to cover up and replace any sounds that bleed through the passive seal of the comfortable silicone tips. This “block and replace” noise-masking technology is different from active noise cancellation, and our testing indicates that it’s more effective for the sleep use case in a bedroom environment.

Can I stream anything?

Yes. Ozlo Sleepbuds® can stream anything (Netflix, Spotify, Audible, Youtube, etc) that a normal bluetooth headphone can.

Do they have an alarm?

Yes, Sleepbuds® have a built-in private alarm which can be set up through the Ozlo app. The alarm doesn’t require the phone to be connected, and still works even in bluetooth disabled mode.

Is there a phone-free mode?

While a phone and an active bluetooth connection are necessary to initially set up and to stream audio, your Sleepbuds® can be configured to automatically play your built-in Sleep Sound as soon as you take them out of the case. No phone or bluetooth connection required.

What is the wireless range?

Ozlo Sleepbuds® have a range of up to 10ft (3 meters) from the Smart Case. The Smart Case has a range of up to 10ft (3 meters) from the source device (like a phone). This range may be reduced by physical obstructions, such as walls and doors, or by interference from other electronic devices. 

Does the Ozlo app work on Android and Apple Devices?

Yes, the app will be available for Android phones running Android 12 or later and Apple iPhones & iPads running iOS 17 or later.

No.

Can they take phone calls?

While there is a microphone in the charging case (to assess the noise level in your sleeping environment), there is no microphone in Sleepbuds® to support phone calls.

    Back to sleeping all night!

    After 30 days of use, I am very satisfied. They replaced my Bose which stopped working. Read the installation instructions first! Setup was easy with no connection issues

    Love them!

    I had been looking for earphones that I could use to sleep. These worked perfect! They are super comfortable don’t even feel them in and they definitely help with noise canceling too. Slept through my alarm one time but they do have the option to set an alarm so it hasn’t happened again. Have recommended them to everyone. Worth the price.

    so far so good

    Effective like Bose sleepbuds but so easy to use and hopefully more durable. I need much more time to test their longevity! Smooth and effective! Could use more options for whitenoise, meditative yoga music, sounding, chiming sounds,Tibetan singing bowls etc.. Now I may just not know how to access different sounds. If so that’s on me. That would just make them

    heavenly if they did have great sleep sounds and it’s just me who is definately not tech savvy!

    Emanuela, this made us smile! So glad you're loving how easy the Sleepbuds are—and yes, here’s to major Bose energy but with smoother vibes 😌 If you ever want help finding more sounds (or if we do need to add singing bowls 👀), just shoot us a message at support@ozlosleep.com. Sweet dreams and sound journeys ahead! 🌙✨

    Saved my marriage

    Both my husband and I snore. These are so comfortable so easy to use and make my night so much nicer. Sometimes I use the ocean sound at a very low level and sometimes no noise at all. The earbuds block sound perfectly.

    Hey Kelly — wow, "saved my marriage" might be the best review title we've ever seen 😄 So glad the Sleepbuds are bringing peace to both you and your husband's nights! Love that you've found your perfect setup with the ocean sounds on low (or no sound at all) and that the blocking is working so well for the snoring. Thanks for sharing this—it genuinely made our day. Here's to many more harmonious nights ahead! 💤

    So far so good

    Loving these, totally transformed my sleep. I work shifts and being able to block out all other noises has dramatically helped me. They were initially uncomfortable for the first week or so but now I don't notice them at all. Not had any connection problems as others have had. Would definitely recommend.

    Hey Stephen — so glad to hear the Sleepbuds have transformed your sleep, especially with shift work! That's exactly what they're designed for. Thanks for sticking with them through that initial adjustment period—it's pretty common and sounds like it was totally worth it. Really appreciate you sharing your experience and the recommendation. Here's to many more nights of uninterrupted rest! 😴
