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.

    Love My Ozlos

    Was so disappointed when my Bose Sleep buds stopped charging! Was so happy to find the Oslo’s. They are even better than the Bose Sleep Buds!!

    Hey there — glad to hear the noise masking is doing its job! Totally hear you on the comfort though. Everyone’s ears are a bit different, and we know that finding the right fit can make all the difference for sleep.

    If you haven’t already, feel free to reach out to us at support@ ozlosleep .com

    — we’d love to help troubleshoot and see if a different tip size or fit combo could work better for you.

    Thanks for giving us a try and sharing your honest thoughts!

    Superb noise cancelling and comfort …

    Like others I was very disappointed that Bose had stopped manufacturing their equivalent of Sleepbuds but delighted Ozlo was a viable alternative. I am delighted with them especially as our teenage daughter has worked out how I can play podcasts to fall asleep to which then switches to white noise sounds which cancels out my husband’s frequent and noisy snoring! They are fabulous! The only downside is that our daughter wants a pair now so she can sleep better - she has Autism and ADHD and sleep is a frequent challenge for her as her mind is constantly processing thoughts. Given their cost, she’s going to have to wait until Christmas but I think she’ll be OK with that.

    Fern, this is such a lovely review—thank you! 🙌 We're so glad Ozlo stepped in after Bose and that your daughter cracked the perfect podcast-to-white-noise sleep setup (genius, honestly). It sounds like it’s been a total game-changer, snoring and all! Fingers crossed your daughter gets her own pair under the tree this year—she clearly deserves them. 😴💙

    Terrible support/customer service

    Think twice before purchasing and if you do, pay attention to the 30 day return window. I was able to use the buds once and they seemed promising. However after one use they stopped working and the case kept draining battery even though the buds weren’t in use. Support was so slow to respond and I had to send follow up emails each time to get a response. Eventually they agreed the unit was defective and offered a replacement. However, due to their slow response times my 30 day return period was about to expire. I couldn’t be sure I wanted to keep them since they only worked for one night. Support refused to extend the return period based on shipping the replacement unit. Their only suggestion was to return my pair and place a new order. That’s an absolutely ridiculous response given that they sent me a defective unit. They also wasted two weeks of my 30 day return period because it took two days each time to get a response from support each time their suggested fixes didn’t work. I can’t recommend and won’t be buying a new unit to replace the defective one.

    I really didn’t like these at all. The noise cancellation made me nauseous above 30% volume.

    Every time you use them they need to paired with your phone. Every other blue tooth device I have you pair once and it’s paired forever. This would also interfere with my phone volume when I wasn’t using them. My phone would try sending all volume to my Bluetooth device that wasn’t active.

    They are marketed for side sleepers, but I couldn’t fall asleep with them due to pressure and eventually hurting my ears.

    Basically I didn’t like anything about using them. Not for me.

    I returned these.

    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! 😴💙
