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

iOS

By supporting iOS 17 and above, we support all Apple phones released from 2017 and later. Focusing our support to 7 years of devices allows us to provide the best experience for our users by enabling us to focus on supporting Apple’s latest feature sets and security enhancements while still supporting a wide range of devices.

Does the Smart Case support wireless charging?

No.

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.

    The most comfortable earplugs I have ever worn!

    I mainly use these as simple earplugs, with no white noise or audio. They're more comfortable for me as a side sleeper than any conventional earplugs I've tried (and I've tried many!), plus I can set an alarm for the morning that won't wake my husband. It has saved us many arguments!

    On bad nights I have the option to add white noise or listen to my own music or podcasts, and can drift back off to sleep without needing to physically switch between headphones and earplugs. Perfect.

    Great Sleep Aide!

    I previously owned many of the Bose Sleepbuds, but I like the ease of use of the Oslo better. I could not sleep without them and purchased two in case one of them isn't charged properly or quits working.

    These earbuds saved my sleep and my health

    I have never wanted to review a product so highly. I've struggled with nighttime sounds, including those coming from my husband:), for decades. No other buds have worked. No white noise machines have worked. Ozlo Sleepbuds do, and they are comfortable. I like the choice of sounds, and found my perfect one (brown)at just the right volume. Best gift from my husband or anyone ever.

    2nd pair

    This is my second pair of Ozlo sleepbuds. When I purchased my first pair over a year ago my sleep improved in such a huge way. Sleep was once something that was elusive, if I was lucky I averaged 4 hours a night and not any time that was consistent. When I decided to order from Ozlo my from 4 hours of interrupted sleep to 7 hours with so much more consistency. I will never live without them.

    Excellent noise cancellation

    These sleep buds are great!

    Outstanding noise cancellation especially when paired with the white noise options (rainfall, ocean, etc).

    Comfortable for side sleepers all night long.

    No issues with battery life.

    The one room for improvement: the charging case is large to travel with, but these are intended as sleep buds, not general purpose earbuds
