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.

- SSonja9 hours agoReviewingOzlo Sleepbuds 2Rated 5 out of 5 stars5 Stars
I have only ised 1 night as i just received it but I'm impressed already. The buds are comfortable they dont slip out. The spunds are soothing and i like you can listen to their sounds or anything you have on your phone. It will change over to a sleep sound once you fall asleep to help you stay asleep. It tracks your sleep patterns. It helos to block out external noises which for a nurse who works night shift is a huge plus. The sleep mask is so soft and comfortable with cushions around thw eyes for comfort and complete light blocking. This was the best purchase.
- ESEli S.Verified BuyerYesterdayReviewingOzlo Sleepbuds 2Rated 5 out of 5 starsI had the previous version, V2 is a big step up for me!
A couple of changes have changed my usage to a significant degree.
1. The battery life is now amazing! I used to wake with the battery running low, and in some cases the buds went to ground waiting for the alarm to go off. Now I wake after 7-8 hours and the batteries report 40+% remaining! Not sure the truth in that number, but I haven't had any "quiet" wake-ups.
2. Big change here is that if I wake in the middle of the night (as I regularly do), the buds reconnect instantly to my phone, and I can start a short radio stream before dropping back to sleep sounds. In V1, I would have to put the buds back in the case to reconnect and start the 10 minute countdown to get streaming going again. This is SO MUCH BETTER!
- DJDebra J. H.Verified BuyerYesterdayReviewingOzlo Sleepbuds 2Rated 5 out of 5 starsLove my Sleepbuds 2
I love the upgrades made to the Sleepbuds2. They are always ready and connected when I put them in at bedtime. I use them to stream a Hallmark series all night long. That keeps me from waking up and my mind racing. It's been a long time since I have had consistent nights of deep/REM sleep that puts me in the top 5% for my age group. Thanks, Ozlo.
- TOTheresa O.Verified BuyerYesterdayReviewingOzlo Sleepbuds 2Rated 5 out of 5 starsBest thing I ever did for my sleep
Love my sleepbuds so much. This new version fits even better than my last pair. They’re a tad smaller, lighter and more comfortable. I love seeing how many sounds are getting muffled in my daily sleep reports :) Best money ever spent on helping my sleep improve!!!
- MDMatt D.Verified BuyerYesterdayReviewingOzlo Sleepbuds® 2Rated 5 out of 5 starsThe product just keeps getting better!
I’ve been using the new model of sleep buds (I had been using the older model for a few months before this) and I’m having such a better experience with the new model. I can’t really place why I feel that way, but things work better than before: such as stronger battery life, and I don’t always have to be tethered to the app all the time.
Cheers to the Ozlo team for an improved experience!
- LSLeila S.Verified BuyerYesterdayReviewingOzlo Sleepbuds 2Rated 5 out of 5 starsGame changer
As someone who is an extremely light sleeper and has had insomnia since childhood, I have tried pretty much everything out there. These Ozlo Sleepbuds 2 have done the trick. We have a deaf 21 year-old cat, who likes to sing the songs of her people at all hours of the night, and I now sleep right through it. They tick several boxes: customizable sound (love that I can program to listen to music and then transition to sleep sounds), volume can be adjusted, they don’t hurt my ears or fall out (small ear canals so most earplugs/buds do), and I can have an alarm without waking my husband. The app is great, too.
- RTRegina T.Verified BuyerYesterdayReviewingOzlo Sleepbuds 2Rated 5 out of 5 starsThe upgrade is wonderful
I have the original and this upgrade is awesome for the simple fact that I don't have to have my phone/iPad in my bedroom to have it work! Love!
