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.

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.

    Simply the best

    These sleep buds are simply the best. They are comfortable even for side sleepers. I use the sounds offered on the app. I do not use streaming or alarm. They last for at least 9 hours.

    These are amazing

    I used to use the Bose Sleep buds and have been looking for a replacement ever since they stopped working. These are even better. Sound quality is incredible and like all the features and options.

    Fantastic product

    Sleep is getting better. I used them for the 1st time this week whilst away in a hotel and I slept so well as they blocked out any external noise

    Amazing!

    The buds are really comfortable and block my ears from hearing the freight train snoring. I love them and will never be without them!

    The battery life is fantastic. I’ve had them for 2 1/2 years. The Bose earbuds lasted only a year. Great product!!

    Incredibly helpful!

    I’m ex-military with severe tinnitus and really bad sleep. The Oslos are comfortable to sleep in, and it really helps to have either white noise or an audio book playing that doesn’t disturb my wife’s sleep. I can’t go without them now.

    Great for blocking out my husband’s snoring

    Marriage saving earbuds!!! My husband snores and I’ve tried so many noise blocking earplugs and earbuds to block noise and sleep next to him: foam earplugs, a headband with speakers built in, Bose QC, Apple AirPods. All of those aren’t comfortable to sleep in and make my ears ache and hurt in the morning. I bought these and they are completely worth the investment!! They are small enough to comfortably fit in the ear and they stay in all night. While playing white noise I couldn’t hear my husband snoring. You can use the Ozlo app to choose white noise or play white noise from your phone. I’ve been so pleased with these so far.

    relief from partner snoring!

    These tiny earbuds have saved me! I'm sleeping more soundly, without outside noise disruption. It took a few tries to get the correct fit - I chose the smallest earpiece covers.
