- Sleepbuds® | Comfortable Side Sleeper Headphones | Up to 10 Hours of Bluetooth LE Streaming | Science-Backed Sleep Sounds | Snore Blocking Comfortable Earbuds

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!

Had them less than 24 hours and I already know … they are going back. Bottom line: Don’t waste your time and money with these. Go for a cheap, ~35-ish pair and get about the same performance with better battery life and a better charging case. Or - if you only care about noise blockage and not streaming or sleep sounds, get the wax ear plugs ($15 for 10 reusable pairs) and sleep sleep sleep away in silence, even on an airplane. I read the reviews of Ozlo and decided to try them anyway, even with the mixed sentiments. I am an experienced user of sleep buds and ear plugs due to years of travel, noise sensitivity, and a snoring spouse. These absolutely are not worth the money. The flags arose even before sleeping with them. Red flag #1: Trying to download the update. They were connected to my phone but the app didn’t recognize that and wouldn’t install the update. Tried over several hours and this morning. No dice. Red flag #2: They don’t charge evenly. Not sure how or why, but after several hours in the case, one was 100% and one was 3%. As another reviewer said, the case looks and feels nice but is impractical and, I think, very sensitive to perfect positioning. If the case is anywhere but on a flat surface, I fear it won’t work properly. Not good if you travel. Red flag #3: The fit isn’t snug enough to block sound. Nuff said about that. Also, one came out of my ear while sleeping and I had to look for it. You don’t want that on a plane or in a hotel room. For fun, at the same time, I purchased a $35 pair to evaluate them side by side. I am keeping those. They are slightly bigger but still comfortable and, for the money, seem to do just as well. They also have a cool feature where you click four times and it turns them to sleep mode so that you don’t press buttons via the pillow while you sleep. They give you the audible that they are in sleep mode. Great. I also now have the Soundcore A30s and those are also far better than the Oslo’s. If Beats Fit Pro were smaller and had a feature to go to a similar sleep mode, they would be fabulous sleepers for home. I also have the Philips Kokoon. I would recommend these over the Ozlo, even though their sound quality isn’t the greatest. The best thing about these is that they connect quickly and easily, and the left and right are held together by a wire that goes behind your neck. It’s not bad and you get used to it. That’s also good for airplanes and hotel rooms because you are less likely to misplace one. Skip the Ozlo’s. Not worth the money.

I bought these in January, 2026. I’ve owned Bose sleepbuds and they were helpful but they didn’t have the option for Bluetooth. The Ozlos do and they connect perfectly and easily every time I wear them at night. THE CRITICAL THING TO NOTE IS TURN OFF OTHER BLUETOOTH DEVICES. IF YOU DON’T THE OZLOS CAN “ROUTE” TO UNWANTED DEVICES AND CAUSE A DISCONNECT TO THE DEVICE THAT SUPPLIES THE SOUNDS YOU WANT TO HEAR THROUGH THE OZLOS. #1. I live near an airport used by both commercial flights and military jets. At night, the noise is unbelievable when very loud fighter jets pass overhead at 900 feet (I’m a pilot and can verify altitude knowing what the glide slope is here.) Now that I’m using my Ozlo Sleepbuds I’m able to sleep through the night, never EVER bothered by outside noise now such as military aircraft, barking dogs and thunderstorms. #2. My wife snores like a chainsaw. Maybe the neighbors down the road can hear her but I can’t now that I’m wearing my Ozlos. #3. I sleep on my side and these don’t bother me a bit. In fact, the Ozlos are much more comfortable than Bluetooth sleep masks that didn’t block exterior sounds at night. #4. I also have an auditory problem called TINNITUS and that made me get really bad sleep scores at night but with the flawless Bluetooth capability of the Ozlos, I’m able to play pleasing soft sounds that drown out the TINNITUS and my sleep score improved significantly. (thank you Ozlo.) I suggest using “Sleep Sounds” found on YouTube. WOW, a lot of the sleep videos on YouTube that are very helpful for tinnitus and people who get help relaxing at night. #5. These easily placed in my ears, they are very comfortable and the Ozlos quickly connect to my iPhone through the Ozlo app. These come with optional ear fittings for people having different size ear canals, so you’ll rest assured that they won’t fall out of your ears when snoozing. The app quickly connects to the Ozlos and that same app has an assortment of sorts sounds to help drown out exterior noises but for my tinnitus I use a app called “MyNoise”and when I use that app, the connection is very quick and I have dozens of pleasant night sounds to choose from. #6. Each and every night, I’m able to wear the Ozlos for 8 hours and they hold a charge and never have “knocked” out. When the Ozlos are placed back into the charging case, they quickly and easily go to “full charge.” The charging case works really well and on occasions when my wife wakes me up, I easily can place the sleepbuds in the charger when the lights are turned off. The easy-to-slide lid closes on top and and they are easy to remove again when I come back to bed when it’s dark. Here is THE BAD NEWS THOUGH… I paid $297 for the Ozlos and they are worth every penny.BUT THE GOOD NEWS FOR YOU IS… the price has dropped. Bottom line, my sleep has improved and I am not bothered by that “chainsaw” in the bed next to me.

I've been using these earbuds since the first week of November, 2024 and they really do help me fall asleep and stay asleep. Once I settled on the best fitting ear bud tips, they were pretty comfortable and I can sleep in any position without really even noticing that they're in my ears. There is still a tad bit of ear fatigue in the morning, but it subsides quickly. The various Sleep Sounds are pretty good for the most part. I'm particularly fond of the Rain, Crimson Cloak, & Fireplace sleep sounds. The others are okay, but I can't bring myself to try the Babbling Brook one, because I irrationally fear it will make me pee myself in my sleep.. My favorite feature of these buds is the Alarm. Before, I would just use my phone's alarm, but I would need 4-5 separate alarms that would go off at different times before I would wake up. My wife was not a fan of this, since she wakes up an hour after I do. Now that I am using the alarm that's built into the Ozlo app, I only need 2 alarms to wake up. I'm sure that my wife much prefers this setup. The alarm choices are also quite pleasant. They're not harsh, so they don't jolt you awake. Instead, they gently wake you up, which is nice. Now for cons: - First, and foremost, they're expensive. $300 is steep for any set of earbuds. - I exclusively use these for the Sleep Sounds & I don't stream anything from my phone. Because of this(and another issue mention below), I only use these in "Battery Saver" mode, which turns off Bluetooth after 10 minutes. This greatly increases both the battery life of the sleep buds over night, but also the battery life of the case itself. The downside to this mode is that once the Bluetooth turns off, the only way to reconnect the buds is to put them back into the case. This is pretty annoying if you're 30 minutes into laying in bed and decide that you want to change to a different Sleep Sound. - Connecting to the buds in the app seems to take 30-45 seconds, even though they connect to my phone within just a few seconds. When I slide the case open, only a few seconds go by before the Bluetooth connection icon appears on my phones Notification Bar, and I'm able to listened to whatever Sleep Sound that I have selected right then. Now if I want to get into the app to change settings, the app seems to take 30-45 seconds to connect to the buds. - I wish there was a earbud tip that combined the actual tip size of the Medium, but the "Finger"(the piece that holds it into your inner ear) size of the Large. Both features on each size get bigger/smaller accordingly, but if the combination that I mentioned existed, that would be perfect for my ears. - I wish there were a few more Sleep Sounds to choose from. The ones I mentioned are my favorites(even though the Fireplace one is noticeably repetitive), but it would be nice to have a bit more variety. - After the first week, or so, of getting these, I noticed that the buds would cut out for a couple seconds a few times a night, which was jarring. This is the main reason that I switched to the Battery Saver mode, which solved the issue. - The sleep tracking feature, aka "My Sleep - Sleep Data", has been "Coming Soon" for month now.. EDIT: It seems that the case is unable to charge the earbuds while the case is plugged in and changing, or there is at least a bug that makes it seem that way. Twice now I've went to use the buds, only for one of them to die within a few minutes. Both times happened right after unplugging the case from the charger that I also use for my phone.

IF U CAN AFFORD THESE BUY THEM! Im a light sleeper and side sleeper with a husband who snores LOUDLY. Like SHAKES the bed loud. 20 years of trying EVERY product on the market from custom molded earplugs to white noise machines to beds with antisnore modes and vibrating pillows and noise blocking headphones and sleeping pills to all of the above at the same time…you name it ive tried it. These SLEEP BUDS have CHANGED MY NIGHTS and improved my marriage and we can actually sleep in the same bed again! I now find myself frequently sleeping thru the night, or sleeping in late when before i was giving up and just getting up At 4:30am since there was no going back to sleep with the noise. PROS: I can sleep comfortably on my side while wearing these and the battery lasts all night. I do recharge them every day faithfully because i am now Completely addicted and feel panic if they are not charged at bedtime They are especially valuable when traveling as i can now sleep in noisy environments. I love the sleep Sound SOAR as it sounds like flying in a jet and the low frequencies block snore noise for me. Lots of other good noises too. I also LOVE being able to play my audiofiles and have it auto transition to a sleep sound once i fall Asleep. Love this feature—make falling asleep easy and staying asleep easy. They stay in place. I used 2 sizes to get the best fit For me. CONS: They dont charge well unless on a flat surface—so traveling requires planning—you cant toss them In the case and expect them To recharge rolling around in your bag. Pricey but honestly i would buy a pair every year if needed. My improved sleep is worth every cent. Rarely the bluetooth falters for a few seconds. The initial setup was a bit tricky and resetting them up Is tricky. You cant just share them to another device easily. That said i guard them with my life so sharing isnt an issue. These are NOT suited to be dual daytime earbuds as they have no controls on them —this keeps them small and comfortable for side sleeping. These are noise masking rather than than blocking. The seal Is not tight enough to really block noise (I previously used swimming wax earplugs) So you do need to play a sound to get the noise canceling effect. The looser seal makes them more comfortable to wear all night in my opinion tho. They’re addictive. Summary—Ive been using these for over 6 Months now. LOVE THEM. if you are a side sleeper struggling with a noisy sleep environment these are worth every $. Good sleep makes you a nicer human and you deserve rest. This is by far the Best most effective product ive ever used!!!!

*Changes Below... I have been extremely torn on whether to give these three or four stars. I would say 3.5, but I can't, and I can't say they are a full 4/5. Despite what I am about to say, I am very glad these exist. I am glad people are trying to do this after Bose proper decided to kill the product/project. Good sleep is so important for health, and for me, noise is one of my biggest problems when I'm trying to sleep. And I travel for work. I spend about half my nights NOT at home, and it isn't fun. I have to have tools to block noise. My wife started snoring after child two. It's off and on. Ear plugs and sound machine wouldn't do it. I am not sure whether these block it because she doesn't always do it. But she hasn't woken me up in the couple weeks I've had them. One big issue is that if you're side sleeping, the snoring comes through the bed and pillow, regardless of sound machine or ear plugs, which is what I hope these solve. That said, are these better than ear plugs and a white noise sound machine? Maybe, but not by much. At least not at a volume that will last the night. I will say these are way more comfortable than ear plugs. That is an amazing step. But, $300. The description says "up to 10 hours of Bluetooth LE Streaming." That is being VERY generous. I've used basically exclusively the power saving Bluetooth mode which turns off streaming after 10 minutes, and with volume set between 64% and 75%, and after 7-8 hours of use, I have woken up with them at between 5% and 10%. In my picture, you can see the left is at 7% and the right at 10%. The fact that they aren't evenly draining when brand new is concerning. 64% volume also isn't that loud with my chosen sound. If I had to crank these up, I doubt they would get me through the night. Might I also remind you that Li-Ion batteries have so many charge cycles in them before they lose capacity. 300-500 is the general limit. So if you use these every day, with them barely scraping through a night's sleep as new, I doubt they will last much over a year. $300. Another issue I've been having is when I go onto my side, if I don't rest my head just right on the pillow, somehow the earbud sound gets blocked in that ear. I am not sure if it's just me or the earbuds. I have actually had that wake me up a couple times because I was moving around and the sound would stop and start in my pillow ear. I still use my sound machine with these, so I might try using the sleep timer off since falling asleep is the hard bit, and it should prolong the battery life. One thing I hate is the case. I really do. It has a slide open, spring assisted lid. I frequently find the case open in my travel bag and they're connecting to my phone unwanted. It's nice and all. It feels nice to open, and it's a clever, different design. But I think there's a reason most use a clam shell hinge open case. In practice, this doesn't work all that well. The bottom line is, if you have tried ear plugs and white noise sound machines (lectro fan is awesome), these may be a good step, if you have the money. But don't spend money you can't afford if you haven't tried the other things. Overall, I would say these are very impressive. They do last the night at this point. But I am worried they won't do that for long if I need sound all night. Hilariously, the alarm is advertised to not startle you or your partner. Yeah... The other day was the first time I recall being startled awake by an alarm (that wasn't my backup scary alarm), and me jerking awake also woke my partner. They are right in your ear and they don't ramp up like my phone alarm. They just go. But I probably would get used to it and not do that. The tech is certainly cool. The way it stores sounds on board and reconnects to sound your alarm is a neat way to conserve precious battery. If these were $150-200, or the battery life was much more promising, I would give a solid 4 or 5 stars. Edit: After a month of wearing these off and on, and every night at home and thinking they were working, it turns out I was just already sleeping at the right times. Just like before I used them. I have finally tested them against snoring, air conditioning fans, etc. Anything that produces a low rumble just comes straight through. I just woke up having to take care of business. My sleep timer had already shut them off. So I started them back up. Snoring. I changed them from 66% to 100% volume. Still there. The snoring just rumbles straight through the pillow, blanket, etc. I would honestly say that these are equally effective as ear plugs and a good sound machine like a $40 Lectro Fan. These still are more comfortable than any ear plugs I've tried. But Lectro Fan will 100% last the night at whatever volume you set.

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.] - Update 12/10/2025: The left earbud went back to only playing at half the volume. I have tried all troubleshooting steps and the issue remains. I've given up on fixing this and just have been using it as-is. - Update 3/6/2026: The sleepbuds now disconnect from the case very frequently, even if they're close to the case and phone (even a few feet). I don't know if this was caused by a recent firmware update, or what happened. I would consider them unreliable to the point of being unusable. They're more like pair of earplugs now. I'm really disappointed.

As a former user of the Bose Sleepbuds, I’m happy that Ozlo carried on the torch. They are very comfortable and perfect for side sleepers. I have not had any issues thus far. The set up was a bit time consuming due to required updates. The buds connected to my phone without any issues. After a few nights, I noticed the right bud’s battery level would be about 5-10% lower than the left bud. I ended up turning the sleep tracker function off, and that took care of it. Maybe the right bud is used more for sleep tracking data, not sure. I use my watch for sleep tracking, so I don’t need the Ozlo’s to do it. The results seemed pretty accurate though. And the buds do last all night for me. 8-9 hours or so. I don’t use them for streaming any audio. The masking sounds that Ozlo uses are great. There are plenty to choose from. However, most of the sounds needed updates. That’s about 2-3 minutes for each sound to update. The buds themselves, can’t hold the entire library of sounds, so you may need to swap sounds to your liking. Again, this is a 2-3 minute process per sound. Not a deal breaker for me. I’m just glad they have plenty to choose from. A lot of the negative reviews I read were complaints about sound quality. Keep in mind these are made for sleeping and noise masking, not jamming out or head banging to your favorite tunes. As I mentioned earlier, I haven’t used them to stream any audio other than the masking sounds, so I can’t comment on the audio quality. I use proper earbuds for listening to music and streaming. To sum it up, I’d recommend these for better sleep. I’ve been using this style of sleep buds for many years now, and my sleep has improved a lot. Hope this helps.

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.

Very comfortable, great sleep aids, block out most external noise

Les Ozlo sont très confortables. Bien sûr, on les sent dans les oreilles après quelques heures, mais elles restent nettement plus supportables que les bouchons classiques du commerce. On peut dormir sur le côté sans problème. Le bruit de fond, qui peut démarrer dès que vous les mettez ou automatiquement lorsque vous vous endormez, couvre efficacement les bruits environnants et facilite l’endormissement. Tout dépend du volume : n’hésitez pas à l’augmenter si nécessaire. Un seul conseil pour éviter de perdre du temps : lisez attentivement les instructions avant la première utilisation. Par exemple, il faut toujours commencer par ouvrir l’application sur votre téléphone, puis ouvrir le boîtier et connecter les écouteurs, en attendant que les lumières à l’intérieur du boîtier s’allument. À ce moment-là, vous pouvez les sortir. De même, après utilisation, lorsque vous les replacez dans le boîtier, il faut le fermer, puis le rouvrir et le refermer afin qu’elles se déconnectent correctement. À noter également : une petite LED verte s’allume sur le boîtier lorsque vous le mettez en charge, puis s’éteint. Cela ne signifie pas que la charge est terminée ; le boîtier continue à charger normalement.

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.
