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.

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.

    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!

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! 😴💙

    Saved my relationship..

    Saved my relationship! My partner snores really loud, or at least she use to, & her daughter is very noisy @ night. I now fall and stay asleep all night. The option to have the sleep sound start once I’ve fallen asleep is amazing. I would definitely recommend these to anyone

    Sean, we might just frame this review! 🙌 From snoring to serenity—Ozlo for the win. So glad you're loving the delayed sound feature (such an underrated gem), and even more thrilled that you're finally getting uninterrupted sleep. Appreciate the love and the recommendation—sleep saved and relationship secured! 😴💙

    Love them!

    This is my 3rd pair. I keep one at our vacation home, one at home and this new set for traveling. I used the Bose version for years and was disappointed when they were discontinued. These are much better—longer battery, interfaces with my phone, etc. I’m a side sleeper and my husband is a loud snorer. These work great!!

    Linda, we love a Sleepbuds strategy! 🙌 Home, vacation, travel—you’ve got all the bases (and beds) covered. So glad Ozlo’s been an upgrade from Bose and holding up strong against that snoring soundtrack. Here’s to peaceful nights wherever life takes you! 😴💙

    Could be perfect

    If only they would work. I’ve set and reset over and over again. Just when I get them working they cut out. I give up for a few months then get around to trying again. Sometimes yes, sometimes, no. For the price they should be less of a problem. I’ve read every instruction and reconnected them a dozen times.

    Hey Theresa — sounds like you’ve been through a loop with these, and that’s super frustrating. You’ve clearly done your part with all the resets and reconnects.

    We’d really like to help figure out what’s going on behind the scenes. Mind reaching out to support@ozlosleep.com? We’ll take it from there and try to get you some sleep, minus the stress.

    Superior to the Bose iteration

    While the comfort is comparable, the longer battery life (can last a good 10 hours) is superior to Bose (8 hours if you were lucky after the first few months), as are the selections of white/background noises. My anxiety to buy extra pairs is real.

    Anthony, this is exactly what we love to hear—a true upgrade experience! 🙌 We're absolutely thrilled that you're experiencing that superior 10-hour battery life and loving our expanded selection of white and background noises. Coming from the Bose sleepbuds, you know exactly what makes the difference, and hearing that we've delivered on both the comfort AND the performance improvements? That's pure validation right there! And we totally get that anxiety about wanting extra pairs—when you've found something that works this well, you want to make sure you're always covered!

    lifesaver!!!

    I was struggling to sleep for months living in an old building on a busy city street, and these have been a lifesaver. I'm a side sleeper; it took me a couple weeks to get used to the earbuds but now I hardly feel them. I keep the volume at 50% or lower and it's enough to tune out most outside noise. I will say they're not noise cancelling so I still have trouble falling asleep with neighbors stomping overhead, but once I'm asleep I only wake up to the alarm in the earbuds. Gone are the days of getting woken up at the crack of dawn by my neighbors' spawn running laps around the apartment! My one complaint is that the connection process is a bit clunky. I wish these would connect automatically when you take them out of the case like airpods so I could use them without looking at my phone at night.

    Hey Caroline! So glad to hear the Sleepbuds have been a lifesaver for city living—that’s exactly why we built them! 🙌 Love that you’ve adjusted as a side sleeper and found the right volume sweet spot to block out most of the chaos (neighbors’ “morning track meet” included). We totally get your point on the connection process, feedback like yours helps us keep improving. Thanks for sharing your experience, and even more for sticking with us for those uninterrupted nights! 💫
