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.

    These are the best! Got for a friend as I’ve had a pair since they launched. Unlike the Bose predecessor that had serious issues, these work perfect. SO sleeps with the tv on and snores, and these do a great job of masking the noise. Customer service is also extremely responsive if you have any questions. These alao work great on planes when trying to get some rest.

    Couldn’t live without them!

    I was a previous Bose sleep bud convert- mine were still working! But I figured they would surely give out at some point so decided to give the Oslos a try. I’ve had them for 3 months and I’m finding them great. I read reviews before I bought them and was a bit worried about the battery life and connectivity issues- so far, they have worked perfectly. I’m enjoying being able to listen to a podcast to fall asleep, and definitely sleeping much better than when I wasn’t using them. I wasn’t using the Bose ones for a while before I got these and I definitely notice a difference- my sleep app from my watch shows a noticeable improvement! They totally work for blocking snoring for me, and just improve my sleep in general. Couldn’t live without them now!!

    Excellent product and outstanding customer service

    I’ve never slept better! I lost a bud and they responded immediately and installed the replacement for me. Truly never experienced such personalized, helpful and responsive customer service. Would recommend to everyone who has ever used a noise machine.
