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.

Focusing our support on more recent devices allows us to provide the best experience for our users by enabling us to focus on supporting Android’s latest feature sets and security enhancements while still supporting a wide range of devices

Does the Smart Case support wireless charging? Minus Plus

No.

Can they take phone calls? Minus Plus

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.

    These earbuds saved my sleep

    Not only am I a light and anxious sleeper, I have a very loud oriental shorthair cat who has not helped with my already fragile sleep. After trying many different earbuds (foam, silicone, loop and other gimmicks) I was nearly all out of options. I was at first hesitant to purchase ozlos due to the price, but became desperate due to my deteriorating sleep and sleep med dependency. Enter ozlos - they have completely changed the way I sleep, I am often able to sleep through the night with a couple of short wakeups and have successfully blocked out my cat who often meows at my door. They also do not come out of my ears all night. I have now become much more confident with my sleep subsequently stopping all sleep medication. My only suggestion is it would be awesome if there was noise cancelling, especially with the price point. Nonetheless, ozlos would have to be nearly the best on the market and they have saved my sleep.

    Saved my sleep life!

    After 15 years of dealing with nighttime noises from my wife due to a medical condition, I have slept without interruption for almost a year. Since the VERY FIRST NIGHT, I have slept through without being woken up. It has helped my sleep quality as well as kept me from waking her several times a night, nudging her out of REM sleep until I could get to sleep. The different sounds and frequencies allow you to pick one that matches the sounds you are looking to cover, so it isn't just for snoring. TOTAL GAME CHANGER. My ONLY take away is when they 'disconnect' in the middle of the night and I have to reboot. But that is only a few times here and there. When they disconnect and I try to go back to sleep, I am reminded of the years of struggles, and it makes me realize how great they really are.

    Lee, we might just frame this review—15 years to sleep salvation! 🙌 We're absolutely thrilled that from the VERY FIRST NIGHT, Ozlo gave you that uninterrupted sleep you'd been searching for all those years. What makes this even more meaningful is knowing that both you AND your wife are getting better rest now—no more nudging, no more disrupted REM cycles, just peaceful nights for everyone. We love that you've discovered how those different sounds and frequencies can be perfectly matched to whatever you need to mask—it's so much more than just snoring coverage! And honestly, we appreciate the real talk about the occasional disconnect issue. The fact that those rare moments remind you just how transformative Ozlo has been? That's the kind of perspective that shows just how life-changing good sleep really is. Here's to many more years of that uninterrupted, game-changing sleep you both deserve! 😴💙

    Was skeptical w/ my snoring husband

    My husband and I have opposite work schedules and for the last year we have been sleeping in opposite rooms because he snores INCREDIBLY loud. Even with my fan setting at the highest I cannot drown out his snoring, and he can’t fall asleep to white noise. Standard earplugs didn’t work, bulky noise canceling headphones didn’t work. I was hesitant to buy these because of the price but I did and they are INCREDIBLE. They fit comfortably in my ears as a side sleeper, and the white noise (Crimson Cloak at 100%) allows me to sleep straight through the night with no waking up to his snoring! We can sleep in the same bed again without any disturbances. It actually improved for our relationship to be able to do that again. 5/5 recommend!!

    Julie, this is exactly the kind of story that makes our hearts full—from sleeping in separate rooms to sharing the same bed again! 🙌 We're absolutely thrilled that Ozlo brought you and your husband back together after a whole year of that frustrating arrangement. We totally get how defeating it must have felt trying fan after fan, earplugs, bulky headphones—everything that should work but just didn't cut it against that incredibly loud snoring! And we love that you found your perfect match with Crimson Cloak at 100%—when you find that sweet spot that lets you sleep straight through the night, that's pure magic. The fact that you're comfortable as a side sleeper too? Chef's kiss! But honestly, what means the most to us is hearing that this actually improved your relationship. Sleep affects everything, and being able to share that intimate space together again—that's what real solutions are all about. Here's to many more nights of peaceful sleep together and that stronger connection you both deserve! 😴💙

    Love the sleep bud functionality but significant battery duration issues after only 15 months

    I purchased these during the Indie GoGo campaign, waited 4 months for them to arrive and received them in June 2024. Up until several months ago I’ve thought they were fabulous, a game changer for sleep and I’ve recommended them to many friends BUT over the past few months the battery capacity has degraded significantly and now they last only about 7.5hrs before they die. Not good when you are relying on their alarm to wake you. I contacted support and since the warranty is only for 12 months, they said all I could do was buy any other pair if I wanted to have more battery life. They did offer $100 off a second pair as I was a “valued backer” but that’s such a disappointing response (and the cost would be more than I paid originally even with $100 off) and doesn’t speak well to their long term commitment to their customers, especially the early backers. I can’t afford to buy a new pair every 15 months when the battery capacity declines well below the advertised duration (up to 10hrs).

    Thank you for being one of our early backers and for recommending us to friends, we truly appreciate your support. We’re sorry to hear about the battery decline, as we know how important reliable performance is.

    Battery life can vary depending on usage, including factors like volume level and certain settings, and sometimes adjusting these can help extend playtime. We see you already have a ticket open, and a senior team member will be reviewing your case to help find the best solution.

    Game Changer

    I purchased the OZLO SleepBuds for my wife to replace her QuietOn SleepBuds. She indicates it’s a significant upgrade. Although the QuietOn buds were effective, they sometimes made her ears sore and provided only noise canceling. The OSLO SleepBuds are not only comfortable but provide soothing backgrounds sounds of variable selections. The ability to utilize the Bluetooth feature is also of value. She is quite pleased with the upgrade and so am I.

    Peter, this is exactly what we love to hear—from QuietOn to Ozlo and what an upgrade it is! 🙌 We're absolutely thrilled that your wife is experiencing that perfect combination of superior comfort AND all those soothing background sounds that QuietOn just couldn't offer. It's so frustrating when you find something that works but causes discomfort, so hearing that she's getting the best of both worlds—effective sleep support without any ear soreness—is pure validation for everything we've designed! And we love that you're both appreciating those extra features like the variable sound selections and Bluetooth capability. When both partners are happy with the upgrade, that's when you know you've found the perfect sleep solution! Here's to many more nights of that comfortable, customizable sleep experience you both deserve! 😴💙

    Love these!

    After having 2 different sets of Bose sleep buds, they discontinued their product. Tried 2 other kinds of buds for sleep. Not satisfied. Then I found this product. Ozlo is amazing! So similar to my Bose, down to the case. 100% recommend if you’re a light sleeper!

    Julie, this is exactly what we love to hear—from Bose to Ozlo and loving the familiar experience! 🙌 We're absolutely thrilled that after trying multiple alternatives, you found us and discovered that amazing similarity to your beloved Bose sleepbuds, right down to the case design! We know how frustrating it must have been when Bose discontinued their product and then going through the disappointment of trying other options that just didn't measure up. The fact that you're a light sleeper and found Ozlo to be the perfect solution? That's pure validation for everything we've worked to create! We love that you're experiencing that same quality and comfort you trusted before, but now with all the improvements and reliability we've built in. Here's to many more nights of that light-sleeper-approved, peaceful rest you deserve! 😴💙
