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.

Focusing our support on more recent devices allows us to provide the best experience for our users by enabling us to focus on supporting Android’s latest feature sets and security enhancements while still supporting a wide range of devices

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.

    So far so good!

    I've used a variety of ear buds over the years to listen to music, books on tape, and YouTube videos. I use them to drown out ambient noise. In recent years these have been Bluetooth buds with wires connecting the buds. Having struggled with the wires I decided to find wireless buds that would have enough battery life to last eight hours. I tried one brand but found them far too bulky to wear comfortably.

    I then elected to try Ozlo buds--been using them for the past few weeks. So far I've been quite pleased with them. I'm still getting used to how they fit and find-even with the smallest set of adaptor earpieces-a bit of pressure in my right ear. I'm also still learning how to set the various setting in the app. I found a sound setting that is pleasing. I initially listen to music or YouTube which switches to one of the built-in sleep sounds.

    I'm pleased that the ear buds stay in all night with enough battery power to last all night.

    When I purchased them I didn't realize there was a limit to how long I could listen to music and/or YouTube. Perhaps I didn't read about how they function in this respect closely enough.

    Game changing

    Have made a huge difference in being able to sleep beside my wife, blocking out snore sounds. Wish I had tried sooner.

    Brilliant

    I used to own some Bose sleep buds but they stopped working some time ago after Bose withdrew support.

    Finally, after a long wait, I splashed out on these Ozlo Sleepbuds.

    After a couple of teething issues with connection - which the latest firmware update seems to gave sorted - i can honestly say they are better than Bose.

    Comfortable to the point of forgetting they are in.

    Soundblocking - amazing. I travel with a friend in his motorhome and sadly he SNORES. I'm surprised we don't get other campers banging on our door at 2.00am with pitchfork and torches.

    All is blocked apart from very occasionally when he exceeds 10 on the Richter scale. (then a prod with a long sharpened pole seems to do the job).

    Excellent job guys, highly recommended.

    Absolutely love these

    I have had terrible sleep for many years but these are a game changer. Super comfortable and they stay in, even with side sleeping. I used to wear the Bose version but these are next level.

    Snoring Problem Solved!

    They are honestly really good and totally worth the hype. The sound masking works great and they’re super comfortable to sleep with. Yes, they’re definitely on the expensive side, but in my opinion they’re more than worth it if snoring keeps you awake.

    Also, since my boyfriend is the snoring one, he’s the one who bought them for me… so I’m extra happy about it 😂 Best gift!

    Best sleep in years

    Bought these to replace a failed pair of Bose Sleepbuds which, to be honest, I had never really been a fan of. Why Bose chose to limit these to streaming sounds native to its app I never did understand.

    The ability to stream what I want through the Ozlo Sleepbuds, added to the fact that they seem smaller and more comfortable (side sleeper), make these perfect.

    I have had the best sleep in years since I started using these a week ago.

    The sound masking is pretty much as good as active noise cancelling. Sound library is good. But having the choice of music, audiobooks, podcasts and other streaming services with the option for these to switch to sounds when the sleep buds sense you are asleep is exactly what I wanted.

    The sleep profiling app is excellent. Reassuring that my Ultra3 and the app see almost exactly the same sleep patterns and data.

    In short - the Oslo Sleepbud product is brilliant and great value. Buy some!

    Pretty Amazing

    There is a learning curve when getting started with these sleep buds. One of them didn't charge the same as the other at first but that quickly fixed itself - just needed longer at the very beginning. I LOVE that I can start out listening to my audio book and then when the timer is up (and I'm asleep) it just switches over to whatever soundscape I have chosen. I don't hear my husband snore AT ALL and I'm a light sleeper. My oura ring now shows longer and deeper sleep results. Couldn't be happier.
