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.

    Best purchase of my life

    I had the bose ones and they had nothing but issues and eventually died. Ive had these Ozlo for years now, hardly an issue. Whenever there was, it was just a restart or update needed. Cant sleep without them, best product ever. The sound options have only gotten better over the years too, I especially like the masking ones, which truly do block out a lot, for a light sleeper like me.

    Nicky, this is what we love to hear! 🙌 So glad Ozlo’s been your go-to for years—especially after the Bose letdown. Minimal issues, reliable updates, and sleep you can count on? That’s the dream. And yes, those masking sounds are chef’s kiss for light sleepers. Thanks for sticking with us! 😴💙

    Absolutely the best - worth every penny

    I was devastated when Bose stopped making sleepbuds, as mine were no longer working reliably, then I was very hopeful when I saw Ozlo on on Indiegogo and backed them. One of mine had an issue during its first year, but after some troubleshooting Ozlo replaced it and the new pair has worked perfectly. Great product, great company, great service - I’m a customer for life.

    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.

    Hey Pip — your review genuinely made our day. We’re so happy Ozlo’s helped you sleep easier (and even beat the meowing cat alarm clock 🐱). Hearing you’ve been able to rest better and step away from sleep meds is incredible. We totally get your point about noise cancelling — while the buds block sound well, they don’t use active noise cancellation just yet. Feedback like yours keeps us focused on what matters most: peaceful, consistent sleep. Thanks for sharing your story — it means a lot.

    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! 😴💙

    Really want these to be my go-to, but…

    Great product design/comfortable, however app needs help…for instance, app states it can “sense” when one falls asleep, but every time it switches to sleep sounds when I am still listening to a podcast…super annoying

    Hey Leigh — love that the design and comfort are working for you! Totally hear you on the app switching to sleep sounds too soon though — that can be really disruptive mid-podcast.

    If you’re still seeing that happen, feel free to email us at support@ozlosleep.com
    . We’d be happy to take a closer look and see if there’s a setting tweak that could help make things smoother.

    Can’t in good conscience recommend

    These had the potential to be as good as the Bose version. However, they never fixed the charging issue present in the Bose version and keep telling me my issue “might” be grounds for a warranty replacement, but then start the debug/troubleshooting process over again with the promise that the latest firmware update will totally 100% fix the problem for realsies we swear… over and over until I’m most likely now out of the warranty period. Great job, thanks so much. The problem is that the firmware updates fix the problem for a few days and then the issue returns and I honestly just don’t have time to constantly be emailing them back and forth so I gave up, which feels like what they wanted by sticking me in a constant reset loop. I haven’t used them in half a year (since my last contact where the update resolved the problem for exactly 3 days before it returned worse than before) because I can’t get them to retain charge for more than an hour of use despite constant firmware updates and factory resets and everything. I wish I could recommend these but as it stands they are actually worse than the Bose ones because I can’t use them, and I’m tired of going in circles with support.

    Thank you for sharing your experience, we’re truly sorry for the frustration you’ve faced. The charging issues you describe and the feeling of going in circles with troubleshooting are not the experience we want for our customers.

    The reason we go through those troubleshooting steps is to make sure the issue won’t repeat itself with a replacement set, but we completely understand how it can feel repetitive. We’ve located your ticket, and a senior member of our team will be stepping in directly to review your case and get this resolved as quickly as possible.

    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! 😴💙
