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 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.

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.

- JZJane Z.Verified Buyer3 minutes agoReviewingOzlo Sleepbuds 2Rated 5 out of 5 starsI fall asleep so much faster
One of the biggest problems I had was the time it took me to fall asleep. It was usually between 45 and 75 minutes. Now, I fall asleep in around 20 minutes. I’m amazed. I don’t even notice that they are in. Once in awhile one will fall out during the night, but it’s never interrupted my sleep. One of the best investments I’ve made for my sleep!
- CSCaron S.Verified Buyer8 hours agoReviewingOzlo Sleepbuds® 2Rated 5 out of 5 starsSecond pair that last longer
Great sleep buds. Easy to use with long lasting battery.
- CBCaitlin B.Verified Buyer12 hours agoReviewingOzlo Sleepbuds 2Rated 5 out of 5 starsLife changing
This is my second purchase of Ozlo earbuds. The originals were great; these are even better. I never thought I’d be able to sleep with earbuds in but these are so comfortable I don’t even notice them once inserted. I was easily able to find my perfect-fit sleep sound from their wide variety of options. I love the new feature where I can listen to other audio till I fall asleep, then my earbuds sense when I am sleeping and switch over to my sleep sound. What amazing tech! Also - my husband snores like a dinosaur and with these I notice nothing and sleep soundly beside him through the night (previously impossible)! They are a must-have for me, and I highly recommend them for anyone with sound-related sleep needs.
- KSKathy S.Verified Buyer13 hours agoReviewingOzlo Sleepbuds 2Rated 5 out of 5 starsGreat Nights Sleep
These sleep buds have been a life changer! My husband snores most nights so it made getting a full nights sleep difficult. I finally get a full nights sleep since I have been using the Ozlo sleep buds. Before there were may nights I would only get a few hours of sleep or I had to go sleep on the couch!
- CWChristopher W.Verified Buyer19 hours agoReviewingOzlo Sleepbuds 2Rated 5 out of 5 starsUseful data
Very useful to have sleep profile day by day.
- SBSally-Anne B.Verified Buyer20 hours agoReviewingOzlo Sleepbuds 2Rated 5 out of 5 starsSleep at last!
These sleep buds are so comfortable to wear, even for side sleepers like me. My sleep has become so much more restful since I started using them.
My only minor complaint is that even when I’ve put them back in the case and stored them away for the day, they sometimes automatically connect to my phone and I’ll suddenly loose sound from my phone.

So far, no complaints!
- KLKim L.Verified BuyerYesterdayReviewingOzlo Sleepbuds 2Rated 5 out of 5 starsControl!
I have options and I have control and that is a very big deal. As a menopausal woman, falling asleep is a mountain. I climb every night. I have always had a hard time turning my brain off and so I listen to a few standard shows every night to turn my brain off enough to fall asleep. The fact that the Ozlo buds allow me to listen to those shows quietly, since is when I have fallen asleep, and switches to white noise… Well, that’s just been a dream literally and figuratively.
