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.

Reviews Summary
Customers say these sleepbuds effectively mask snoring and ambient noise, allowing deeper, uninterrupted sleep. Many find them comfortable for side sleeping and appreciate the ability to stream music or podcasts that automatically switches to sleep sounds. Users report improved sleep quality and longer rest periods. The sound library offers good variety, with ocean waves and white noise being popular choices. However, some experience connectivity issues requiring frequent Bluetooth reconnection, and a few find the earbuds uncomfortable during extended wear. Battery life generally lasts through the night, though occasional charging problems occur. Several customers mention these are improvements over previous Bose models, while others report volume limitations for very loud environments.

    So far they work great.

    Noise canceling is working great. My wife snores really bad and with white noise I can sleep for the first time through the night in years. Thank you so much.

    A life-changer for my sleep!

    I’ve been using these for three years now, and every single night has been wonderful. Before getting them, I had a hard time sleeping because of my neighbors upstairs and downstairs who have small children—now, I don’t hear a thing.

    I also take them with me whenever I travel, whether it’s for work or vacation; I no longer have to worry about whether a hotel will be noisy or not. I always manage to get a good night's sleep and wake up feeling refreshed.

    They are incredibly comfortable and fit perfectly. I love being able to choose from different music and sounds, which accompany my sleep beautifully without ever bothering my ears. This is truly an exceptional product!

    Life-Changing Ear Buds

    I’m a genetic night owl but also a very light sleeper that lives in a condo made of paper maché. I’ve tried white noise, ear plugs and even other ANC sleep ear buds but nothing has worked. The ANC of the Ozlo ear buds is better than anything I’ve used for sleep. They are fairly comfortable for this side sleeper and the battery lasts longer than a typical nights sleep. It’s simple to use, many different sounds to choose from, as well as streaming content if you like. I use a combo of the ANC and one of the “white noise” sounds and no one has woken me up at 6am getting ready for work, yet. My only issue is I have sensitive ears so anything in them eventually irritates the skin. I find silicone to be the least irritating but it’s still not zero.

    As advertised

    Really I have only been wearing them for 3 nights.

    I have tried all kinds of ear buds and ear plugs for sleep in the past. From Expensive noise cancelling ones that were great, but too quiet…to just foam ear plugs.

    Adding in the quiet noise is one of two Ozlo advantages. Once you find the right noise and proper volume setting, it’s gold.

    The way the ear buds fit into your ear is the second advantage… comfortable throughout an 8 hr night and secure… haven’t had them become loose or fall out… unachievable with anything else I’ve tried

    Game changer - sleep has improved & love looking at my stats each morning.

    Great for side sleepers, stay in all night, fall asleep listening to my favourite podcasts, auto switch to soothing sleep sounds as you drift off to sleep, deadens the noise of my husbands snoring. Great purchase!

    Comfortable and effective

    Effectiveness: Noises from partner and random noises in the night have disappeared. You can customize the white noise type and volume - works superbly!

    Comfort: I'm side sleeper, and I barely notice I'm wearing these.

    Battery: The buds last ~10 hrs.
