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.

    They work!

    As promised they sit in your ear and you can't feel them. I've slept in them for about two weeks and am extremely satisfied with their performance. There are a lot of listening options. I also like that I can listen to my saved bedtime stories from my collection. I'm gifting a pair to my husband for his birthday.

    Masking the noise

    I had the Bose sleepbuds, but these are improved. The sounds are better and it does cover the snoring and talking. For this I am truly grateful. I believe it has more options but I haven’t figured out how to use them yet.

    Great Product

    I was a previous user of the Bose Sleep buds so I knew what I was buying and they do not disappoint. The earbuds are very comfortable for slide sleepers, they are good at blocking before any sound is activated. With the sound, lovely and quiet. To be fair some noise still gets through but it’s now at a level where it doesn’t wake me or stop me sleeping, which is the point.

    Best nights sleep ever

    It took me a while to find the right ear buds for me. But these work an absolute treat. One ear bud needed to be slightly bigger than the other and I have a perfect fit.

    If you use the alarm its one you cannot ignore.

    I like the flexibility of being able to listen to 2 hrs of what I want - although I never make it past 30 minutes or I allow the buds to detect when I fall asleep - this function was not always correct - especially when you don’t move around.

    I live in an area where you can hear traffic noise or late at night a tearing past motorbike. I don’t hear these anymore.

    Great when flying too!

    Perfect for side sleepers. Keep them clean - I use a microfibre cloth once a week.

    I cannot do without them and hope they are here to stay.

    Literally changed my life!

    I have had to use wax ear plugs for 30 years as my husband is a dedicated snorer. I was getting all sorts of problems with ear wax, dry skin and infections, but the alternative was no sleep or separate rooms, neither of which were acceptable. Since starting with Ozlo I literally cannot hear him snoring at all and sleep through the night, even though the app informs me that his snoring comes in at a solid 98 decibels most nights!

    Convenient to wear

    I can wear the Sleepbuds all night without any problems; they don’t feel tight and are very comfortable. I’d give them a slight deduction because they don’t block out external noise perfectly, but they’re still quite good.

    Very comfortable

    These are way more comfortable and work better than the latest model of Soundcore, which I also own. I can sleep with these in for a long period.

    Game changer

    These earbuds have been a game changer for my sleep. They are very comfortable and stay in my ears with no irritations or pain (and I am a teeth grinder). There are many different masking and sleep sounds that are available and what I found is some work(mask) better in different environments (like hotel vs snoring)- higher pitch brown noise vs calming sounds like ocean. This is a huge benefit to have many options.

    These saved me when I had to sleep at the hospital with a sick friend and they cancelled much of the typical sounds allowing me to sleep.

    The sleep analysis is in the works (beta) and not reliable yet. I do agree that the battery life could be longer and occasionally when replacing the ear buds into the case, they do not make contact or engage and so do not charge. Just have to make sure they are placed in correctly.
