Product description


How do Ozlo Sleepbuds connect, and what should I do if audio cuts out or the app feels difficult to use?
Your Sleepbuds are part of the Ozlo Sleep System and must connect to the Ozlo App. For stable performance, keep the Case within 10 ft and your phone within 30 ft. If audio drops, place the buds in the Case for a quick reset.
How do I fix audio dropouts or Bluetooth disconnects with my Sleepbuds?
1) Check your audio source (i.e. streaming audio from an app; built-in masking sounds, etc.) & see if issue persists (this usually solves it.) 2) Keep phone a few inches away from Ozlo case. 3) Update firmware in app. 4) Reboot case (close lid 30s.)
Can I stream anything?
Yes. Sleepbuds can stream anything (Netflix, Spotify, Audible, Youtube, Calm etc) that a normal bluetooth headphone can.
What should I expect for comfort and noise masking, and what are my options if something doesn’t feel right?
Use the correct Silicone Eartip size for comfort and performance; four sizes are included. Sleepbuds use noise masking, not ANC. For louder sounds, use deeper masking or higher volume. The one-year coverage covers fit, comfort, and support needs.
Can Ozlo Sleepbuds 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 to support phone calls.
CLINICALLY PROVEN: Our Sleep Technology is Clinically Proven to Help You Fall Asleep Faster and Stay Asleep Longer, Without Pharmaceutical Intervention – and the Associated Side Effects.
STREAM ALL NIGHT: Enjoy up to 10 hours of playtime on a single charge, with the Smart Case providing extra power on the go for added convenience and portability.
SLEEP DETECTION: Sleepbuds’ biometric sensors can seamlessly detect when you fall asleep, auto-magically switching from your streaming audio to built-in noise-masking sounds.
HOW THEY WORK: Ozlo Sleepbuds use an innovative connection system where the Smart Case acts as a bridge—connecting to your phone via standard Bluetooth and streaming audio to the Sleepbuds using Bluetooth Low Energy (BLE). This reduces power needs, allowing for a smaller battery and ultra-tiny size that’s comfortable all night, in any sleeping position. For best performance, keep your Sleepbuds within 10 feet of the Smart Case, and your phone within 30 feet.
IN-EAR ALARM: Ozlo Sleepbuds have a built-in personal alarm that gently wakes you from your sound sleep without jarring you or your partner.
SUPER COMFY: Side Sleeper Approved. Ozlo Sleepbuds feature ultra-soft, squishy silicone tips that mold to your ears, providing unparalleled comfort and a secure-fit, even for all-night wear.
DESIGNED FOR SLEEP, NOT FOR CALLS: Ozlo Sleepbuds are made for one thing: helping you sleep better. They do not include a microphone and cannot take phone calls, because they are not regular earbuds. Instead, they are ultra-compact, incredibly comfortable for all sleep positions, and built to block out the noises that interrupt your rest. Every detail is designed to support better sleep, not daily use.
NOISE BLOCKING: Our soft silicone tips passively block noise, while our Science-Backed Sleep Sounds help cover up noisy sleep-disruptions like snoring partners, loud cities, dogs barking, and more.
SLEEPBUDS LEGACY: With decades of headphone engineering expertise, our team acquired the original Sleepbuds patents to create the next generation—Ozlo Sleepbuds. Redesigned from the ground up, they’re engineered for your best sleep yet.
NO MICROPHONE: These Sleepbuds are built for peace and privacy. No mic means no calls, no voice assistants—just uninterrupted sleep.

A light sleeper no longer being woken up!
I am a pretty light sleeper. I have four children, ages 9-17, and sometimes they stay up late, sometimes they wander into my room to get something or other late at night, sometimes my husband snores or coughs, 🙂 and sometimes we have a train that goes by the house at night. Just typical life stuff, but I crack my eyelid for a second when I hear things, and obviously that’s pulling me out of good sleep. I used to turn on the fan in my bathroom, hoping to drown out some of the noise. I also got a white noise maker to try to drown things out even more. I liked having those things, but I was still being woken up. These sleepbuds are a life saver for blocking all those little noises that would normally interrupt my sleep (even if just briefly).First, they are very comfortable. The medium size fits my ear very well. You need to twist it back into your ear for the little wing tip to fit snugly into the groove of your ear. Once you’ve got them in, there is no risk of them falling out. I am a side sleeper and 95% of the night I sleep on only my right side, so I usually just put the left ear in, and my right ear is pressed against the pillow.The sounds in the app are very soothing. My favorite right now is Crimson Cloak, which has a very nice even tone in the middle range. It’s perfect white noise. I’ve also slept with the crackling fire one, and the raindrops one – and both are also soothing. But, I go back to the simple white noise options most often. There are not very many sleep sounds in the Ozlo app, only about ten (I’d love if there were more options), but I had no trouble finding one I like. Plus, I have a subscription to Headspace and I’m able to use these sleepbuds with their night sounds if I want. One thing I like about the sounds in the app is that they don’t overwhelm. It doesn’t feel like anything is blasting in your ear. The sound almost feels “far away” like you’re hearing it from outside a window. This is not a defect of the earbuds, because I can use the buds when listening to other things on my phone and it sounds great. I think it is a feature of the sounds within the app. They don’t feel overwhelming, and I have no trouble falling right to sleep.My husband thinks I must be getting into a pretty deep sleep when I wear them, because he says I make noises in my sleep when I’m really out 🙂 and I’ve been doing that ever since wearing these. I dream often, so maybe that’s why?? Every morning my husband is asking, “Did you hear me cough? Did you hear me get up in the night? Did you hear the dog bark?” and whenever I answer “no” he is super impressed.I sleep about 7-8 hours a night and the battery always lasts through the night. But, they do have to go back in the case to charge every day. One night I put one of the earbuds back in the case flipped 180, and so it didn’t charge, and that night it did not have enough battery to use it.Connecting them up to my phone was easy. They walk you through how to do it in the app. It took about 30 minutes for the updates to download and then it was ready to go. They auto connect via bluetooth when I open the case. But, one odd thing is that to disconnect them I have to put them back in the case, close the lid, and then turn off my bluetooth for a second so they disconnect. I’m hoping that is something that can be fixed, so they disconnect automatically when I put them back in the case in the morning.My husband keeps talking about wanting to try them, but I’m reluctant to not have them for a night while he tries them out :). I guess I’ll just have to get him his own pair!

Worth $50, not $300
I find it relaxing to listen to audiobooks/podcasts while falling asleep. After using regular earbuds for this for years, I decided to splurge on myself and get a dedicated sleepbud-type product. I picked the Ozlo sleepbuds expecting a premium product experience for the $300 price point. The reality is they are a fussy, buggy product that is (to be fair) quite decent when it works and is awful when it doesn’t. I would return these if I wasn’t past the return window on Amazon.Here are more detailed pros/cons I have found after using them for 4 months:Pros:- The fit and comfort level is quite good. You can sleep on your side while they are in.- The battery life is good enough to get through a night of sleep on a charge.Cons:- They often don’t connect properly to my phone, so I have to repeat specific steps to get them working. Put them both in the case, ensure they are seated properly, open the app, open the case lid, then wait for them to connect in the app before I can take them out and use them. Not a huge deal but again, its fussy.- The sleepbuds must be kept close to the case (like 10 feet), or they will disconnect, forcing you to potentially repeat all the connection steps above if they bug out. So you can’t walk out of a room without the case unless you’re willing to risk disconnecting them.- The case must be kept charged, in addition to the sleepbuds. If the case has no charge, then the sleepbuds don’t work. Maybe that’s obvious to some people, but it is an entire additional device & battery to manage.- The case design, while clever, has a very flimsy hinge. It’s not the type of case you can throw in a backpack full of gear and expect to survive. I don’t have any faith it would survive even a short drop. Given how critical the case is to the device operation, this is doubly concerning.- There are random and intermittent audio quality issues even when the devices are well-charge and located close; pops and audio sources cutting in/out briefly.- After ~3 months of use, my left sleepbud developed an issue where it plays at less than half the volume of the right sleepbud. I can’t hear anything from it unless the volume on my phone is maxed out. Emailing tech support got me a list of basic troubleshooting steps which I followed but did not resolve the issue. They have failed to respond to my request for what next to try (3 days and counting…). [update 4/8: It took support 7 days to respond to my email. By this time I had reset the sleepbuds using the ‘pinhole’ reset button on the case and the left earbud audio was restored. Email support had never suggested this as a step to try, not sure why…I had to figure it out from reading other people’s issues.]

If sleep is a problem, Ozlo Sleepbuds are worth considering
This is actually the second set of Ozlo Sleepbuds that I’ve owned. And I owned a pair of Bose Sleepbuds before that. I loved them before the added the sleep tracking feature and the Sleepbuds are more valuable with the tracking. The sound quality is not as good as my AirPods, but I don’t expect them to be. I can lay comfortably on my side and they last all night. As with any product that is used every day, there is some maintenance. If you let wax build up on the contacts in the case, you are going to have problems; but cleaning with q-tips and rubbing alcohol is straight forward. The sleep sounds included are quite good; but Calm and Moongate have good sleep content worth exploring as well. I can’t claim all my sleep problems have disappeared; but my sleep is significantly better. The noise cancellation works quite well.

Bought these as a replacement for my Böse Sleepbuds which I loved but had problems with that couldn’t be fixed. These are perfect – every bit as good as the Böse were but with none of the battery problems. As a bonus, they can be used as ’normal’ earbuds to listen to anything, then when that ends- switch automatically to the sleep sounds.

Alla fine ho dovuto cedere a causa di vicini estremamente rumorosi e dei loro cani che abbiano in continuazione, notte e giorno.E finalmente ho trovato pace.Mi sono fidato del fatto che fossero cuffie realizzate da ingegneri fuoriusciti da Bose, e che siano sostanzialmente un’evoluzione delle Bose Sleepbuds.Come contro ovviamente bisogna menzionare il prezzo: 350 euro sono tanti.Ma per il resto, al momento, riscontro solo lati positivi. Hanno tante funzioni quindi necessitano di un po’ di tempo per essere sfruttate a pieno, come ad esempio tutte le indicazioni fornite dalle varie combinazioni di led sulla confezione.Mi soffermerò innanzitutto sulla comodità: ci posso dormire tutta la notte senza fastidi e senza perderle nel letto. Grazie ai tanti adattatori credo possano andar bene davvero a tutti.E poi le varie funzioni sono pazzesche: puoi andare a dormire ascoltando un podcast e loro percepiscono il momento in cui ti addormenti per commutare sul suono bianco prescelto (in un’ ampia bacheca di suoni disponibili). Oppure puoi scegliere tu dopo quanto tempo farle passare da streaming a suono bianco.Puoi decidere dopo quanto tempo si debbano spegnere.Puoi impostarle in modo che appena indossate partano in automatico con il suono bianco scelto in precedenza, senza dover passare da telefono. Hanno un’utilissima funzione di sveglia.Ma soprattutto, filtrano benissimo i rumori esterni.Le straconsiglio, a patto ovviamente di voler spendere una cifra che è decisamente importante.

I was very excited and looking forward to receiving the headphones as I am a very light sleeper. While the headphones themselves are good quality and fit well, the software is absolutely disappointing. It seems focused on iOS as the nightly sleep reports are already available for that platform (not on Android). On Android however, the app feels like its been developed by an amateur. Texts don’t fit on the screen and cannot be scrolled so buttons below the text cannot be reached (see screenshot) – Phone is a Samsung S24 Ultra.There are only a very small amount of white noise sounds available which would be an easy one to fix. Apps such as Ambience for example have tons of white noises.As the headphones are of no real use without the app, it would be a good idea to have an experienced developer take a few months and design a proper Android app so the luxurious price tag is actually justified.
