FAQ's
What is the return policy? Minus Plus

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

What is the warranty? Minus Plus

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? Minus Plus

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? Minus Plus

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

Do they have an alarm? Minus Plus

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? Minus Plus

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? Minus Plus

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? Minus Plus

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

    Doing the Job!!!

    The product is good! I do sleep better, which is the most important feature. There are still some (technical?) problems - establishing connection is not always seamless, I still have to understand the analytics (one night I took the headphones out of my ears for a while, maybe like for an hour, but in the morning they showed normal measurement as if they were in my ears...). Generally - I do recommend testing them, especially if you have a noisy "environment"...

    Best purchase!

    I had the Bose sleepbuds before for 4 years and unfortunately one of the bud broke. I’ve purchased the Ozlo ones and it is even better than the ones I had. It changes your sleep life!

    Great for restful deep sleep

    I first bought the Ozlo Sleepbuds in June 2025 after years of struggling to stay asleep and get rest that actually felt restorative. They’re definitely a splurge, but I’m genuinely glad I invested in them because they’ve made a noticeable difference to my sleep quality.

    The app can be a bit buggy, and the initial setup wasn’t the smoothest. I also had some trouble using the Sleepbuds to stream other meditation apps. That said, customer service was excellent — they quickly sent me a replacement pair while I was still under warranty.

    Since using them, I’ve been sleeping deeper and for longer, feeling less anxious, and I’ve even stopped grinding my teeth. Overall, I wake up feeling much more refreshed and better equipped to take on the day ahead.

    Great value

    I finally found some actual sleepbuds meant for side sleepers. I can barely tell that they are there. And I love how simple they are. No useless noise cancelling, no weird buttons no nothing. Just a clever app and you're good to go. Thanks guys!

    Game Changer

    I work graveyard shifts, finding quality sleep with noise upstairs is often hard if not impossible. This has genuinely made my life better. Only thing I wish I could change is the reliability of the connection, especially when you first put them on, and the fact my phone alarms don't automatically sync to the case/buds.

    Life-changing sleep! Thank you for the new earbuds

    Thank you for developing the sleep earbuds again! I've been using them for two weeks and I'm very happy with the results. I sleep much better and wake up feeling great. I hope you'll continue to support this product for a long time."❤️
