You Have Questions. We Have Answers.
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 2-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.

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.

- JSJennie S.Verified Buyer4 minutes agoReviewingOzlo Sleepbuds 2Rated 5 out of 5 starsHappy girlfriend
I have been able to get great sleep next to my snoring boyfriend, I am so pleased with these earbuds.
- RARAQUEL A. W.Verified Buyer2 hours agoReviewingOzlo Sleepbuds 2Rated 5 out of 5 starsGreat
Thank you
- DMDawn M.Verified Buyer7 hours agoReviewingOzlo SleepbudsRated 4 out of 5 starsWonderful
The fit and comfort are nothing short of wonderful. They block outside sounds, neighbour noise, enough of the snoring and let you sleep.
I don’t want to be without mine.
For 5stars, the sound quality could use a tweak, as could the soundcapes included.
- JTJason T.Verified Buyer9 hours agoReviewingOzlo Sleepbuds 2Rated 5 out of 5 starsPerfect for sleeping and listening
I have been on the search for comfortable ear buds for listening to music and books. And I had been searching for buds that were comfortable while sleeping. And I had hoped I could find something to get to sleep (and get back to sleep). Bonus: this product does all three. They are so comfortable in your ear. The soft rubber fits into your ear such that you are confident they won't fall out. And there is no problem when lying on your side.
- MMMonique M.Verified Buyer15 hours agoReviewingOzlo Sleepbuds 2Rated 5 out of 5 starsAn investment, but worth the spend
I have had broken sleep for years, but the tipping point was recently when my husband was unwell and was snoring and coughing all night. I was browsing online at 3am and saw that the sleepbuds 2 had finally released, and I have been sleeping so much better since. I feel more cognitively present during the day and it's great to track my sleep stats over time. my only gripe is opening the case and being blinded by flashing lights when trying to get ready for bed.... hahahahahaha
- KPKevin P.Verified Buyer17 hours agoReviewingOzlo Sleepbuds 2Rated 5 out of 5 starsUnexpectedly, fantastic
I really didn't expect these to work. I have been using foam earplugs to sleep for years and really wanted an alternative. I was very skeptical about these, because they don't fully block ambient sounds. They have been awesome - I sleep really well with them. I'm a side sleeper and they are totally comfortable, no issues at all. I can hear ambient sounds when I need to, but it's like the sleepbuds distract your brain from anything keeping it from sleeping. Really glad I tried them.
- SCSam C.Verified BuyerYesterdayReviewingOzlo Sleepbuds 2Rated 5 out of 5 starsA great successor to Bose Sleepbuds
Very much enjoying my new Ozlo Sleepbuds 2. Having relied upon the Bose version to mask my tinnitus at night for many years, I was quite concerned when they were discontinued — but relieved to learn the core team were continuing with a new venture. I still use them in the same way ie just the sleep sounds playing as the buds are removed from the case. Works a treat and the much longer battery life is a boon.
Not particularly interested in the sleep tracking and I don’t think it’s very accurate either — but personally I feel better without an app telling me I’ve had a bad or good night’s sleep when I can work that out already! Very much a recommended product though.
- MCMariela C.Verified BuyerYesterdayReviewingOzlo Sleepbuds 2Rated 5 out of 5 starsWorks great!
When I first tried it I couldn’t sleep from all the noise. The masking does not work for me but the soundscapes are great especially the water sounds. The ear buds stay in all night. I like to listen to something else when I fall asleep so the delayed timer was much appreciated. I also like that I can set a time limit so the sound isn’t on all night. And if I wake up in the middle of the night I like that I can just press the button in the charging case to start the rain again instead of having to fumble with my phone. Everything was well thought out.
