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

UPDATE: I got a great response from customer service. They emailed back and forth with me and finally after taking the steps they suggested twice, it ended with a factory reset which fixed it. The left earbud worked perfectly for 3 weeks and here we are again with the earbud with the same issue. I did all the steps as last time but now it won't even factory reset. So now I start the back and forth with customer service yet again. Earbuds at this price point should work. If I was the only one having issues I would think it was a fluke but clearly I am not based just in the Amazon reviews. I can't fault customer service, they are super responsive but I still want reliable earbuds. I will revisit this rating if I get a satisfactory response from customer service but the cons significantly outweigh the pros at this point. I've been using these for almost 6 months and I'm a side sleeper. They were so comfortable until about a month ago when I started waking up with my right ear really hurting. I thought maybe the cover I was using was worn out because it felt like a hard piece of the earbud was poking into one spot in my ear. I tried all the different covers thinking a change would help but it did not. I tried adjusting how it sat in my ear, no luck. It got so bad that it was waking me up in the middle of the night and I had to take it out. I could live with using just one but that wasn't an option thanks to the next issue. The left earbud either has no sound at all or it is so quiet I can barely hear it with the volume all the way up. This also creates a problem if I want to use both earbuds at the same time because I either get sound from the right only or get a little sound on the left and blasting on the right. I have reset the earbuds and factory reset the case several times. I regularly clean them according to the manufacturer's instructions. None of this works, it just keeps happening. It's interesting to note that so many reviews have similar issues with the left earbud and how many negative reviews are added after 5 or 6 months of use, well past the return date. I also was frustrated with the amount of time it takes to just add one new sleep sound and I can't use my phone or move it away from the case. I just gave up and use the default sounds. I took quite a while to take the plunge and spend $300 on earbuds. If you asked me 2 or 3 months in I would've happily recommended them. I was willing to overlook the bugs and the oddly complicated connection process. I wouldn't say that today. If you want to spend $300 for sleep earbuds that will work for 5 months at best then go for it but I would find another alternative. I really hope I get a real solution from customer service but based on other reviews I'm not holding my breath. Ozlo should have worked out the bugs before releasing these, not over promised what they will do, and definitely lowered the price to match what they could deliver. Seeing how many have posted reviews in May and June about technical issues and not getting great customer service responses, I fear that the ozlo house of cards is about to fall leaving us all with very expensive garbage.

Just returned from a week-long trip where both my wife and I used these every night. We had tried using Bose sleepbuds when they first came on the market and found the reliability to be wanting (Bose tried a few different designs and were very good about replacing the originals and refunding us when they finally took them off the market). The Ozlo Sleepbuds performed very well. They are quite comfortable. They come with 3 sizes of replaceable rubber ear fittings. I used the standard size with no problem and may experiment with other sizes to see if that offers any improvement. The selection of sounds is pretty good. I would be happy if they offered even more of them, but am satisfied with the current selection. The built in alarm is also useful - you will likely use it as the sound masking is very effective and sounds that might normally wake you in the morning are inaudible. And, of course, that means that the sounds you are trying to mask that bother you when sleeping are also effectively eliminated. There is volume control for both sleep audio and alarms as well. I’ve only had these for a few weeks now but so far the quality seems very dependable. They work very similarly to my Apple AirPods, and I suspect that technology advancements since the earlier Bose versions have made it possible to manufacture more reliable small battery products like these. Like Apple’s AirPods, they are stored in a case that you charge and the sleepbuds charge while inside the case. You get about 10 hours from charged sleepbuds, and about 3-4 full charges from the case, which makes them easy to maintain and travel with. They have so far made sleeping while traveling much more enjoyable and I recommend them.

I have a noisy upstairs neighbor in my apartment who stays up late and stomps around well into the wee hours of the morning. It was driving me MAD and making me dread going to bed every night. With these Sleepbuds, I can finally fall asleep and stay asleep without getting startled awake by a thud on my ceiling. While they don’t 100% block out those sounds, they muffle them a great deal to the point where it’s easy to ignore them. They’re also very comfortable and stay in my ears all night. And that’s saying something, because I’ve always had horrible luck with earbuds falling out of my ears my whole life, to the point where I never buy them and only use over-the-ear headphones. I guess I just have weird ear canals…but not with these! I didn’t even have to fiddle with the other sizes of silicone tips; the default ones fit me perfectly. The battery life is sufficient, but not great. Mine are always on the verge of dying when I wake up, but I have yet to have them die while I’m asleep thankfully. The only thing about these that I don’t love is the way the app connectivity works. They have to be in the case for you to be able to use the app, at least at first. You can still use the app for a bit after putting them on. I just think that’s an odd way to handle the app connectivity. UPDATE FEB 2026: I still love these, but I did remove one star from my original rating because there are some quirks about them that arise every few weeks—such as one bud randomly stopping the ability to charge, then back to functioning as normal the next day. They also get dirty VERY easily with dead skin and sweat (gross, I know, but a reality of sticking things in your ears for hours on end). This leads to sound muffling and blockage, making it seem like the bud has stopped working. I honestly think this is why many reviewers claim one of their buds “died” after several months, because of lack of proper cleaning leading to sound blockage. The dirt and debris will usually be totally invisible to the naked eye, leading people to believe they’re clean. After one of my buds went basically totally quiet, only slightly audible at 100%, I got some sticky tack and pressed it against the mesh of the bud a few times…then it was good as new. Full volume. Make sure you clean these often, even when they look fine!

*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’m the worst sleeper! I hated to go to bed at night because knew I would be miserable.I toss and turn all night and my husbands gets super early, and I just wake up with him making me exhausted all day long. I saw ad for sleep earbuds and purchased and returned several pairs from Amazon. I was sleeping in my apple ear pods trying to block out any noise I could but of course that wasn’t working either, they were so uncomfortable for side sleepers. I then reluctantly bought the Ozlo sleep buds and was very taken back by the price. I actually got $50 off.($299) because of a promotion. I figured I would return these as soon as I got them if they were uncomfortable like the previous pairs I purchased. It took me about three nights to get the fit in my ear, and to get them paired and to get them disconnected from the Bluetooth. Some of the annoying things that were happening just takes some patience on how to use them. I did connect with Customer Service and I did not appreciate the long list of things they tried to get me to do with a brand new pair of sleep earbuds that were connected to Bluetooth and up-to-date. However, I will say that for the first time in years, I am now sleeping soundly and not waking up to any noises. I set my alarm now because I have to, or I will sleep right through ‘till 7:30 AM! I am a side sleeper, and every once in a while, I get a tiny bit of discomfort, but most of the time with the sound blocking noises I sleep soundly. I wake up refreshed and in no pain. It has been a relief. I am fearful that they will break and I will be back to square one but so far so good! I will recommend that you are ready to go to sleep at night open the app on your phone, open your Ozlo case, connect the earbuds to your ears close the case go to sleep! In the morning open the app Connect the earbuds back into the Ozlo case make sure they are connected correctly,(the app shows you that they are connected correctly) and shut the case. The Bluetooth will then turn off if you don’t do the steps correctly, it will cause them to not work correctly. This took me three days to figure out sorry :-) but when I do these steps, everything is so nice. I go to sleep, listening to an audiobook, when I fall asleep, the earbuds go to sleep masking sounds automatically, my audiobook, pauses, and I am in a deep sleep until morning for the first time in years! This is a sincere true review, and I am still mad about the price, but I’m grateful for the small size of this noise blocking sleep earbud that actually works.

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.

Such a good product with so many fails. At $250+ price point, how in the world does it not come without a charging adapter but only the cord? Additionally it now has not charged after a week of use. Thought it was maybe the wire or charger but then used another and to the same effect. So weird. Then everytime you want to use it, you cant just put the earbuds in your ear, you first have to open and close case with ear buds inside the case, open the app and then you can properly use. Its so sad cause I love this item and wanted to keep it but its such a hassle of product for such a premium cost. Loved: -really reduces noises, missed my alarm the first night -music tones available in the app are nice, kept with the rain fall -after streaming meditation on iphone, the app can be set to play rain tones after all night while i sleep. -side sleeping approved and doesnt have noise cancelation that can bother but passive which is great for side sleeping -ability to have them turn off automatically after listening to my meditation so I have no bluetooth around me at night(used a few times) -really helps me sleep deeper at night cause mainly they stay in my ear as I sleep thru the night, noticed on my whoop my deep sleep improve. -its also cool to see that it tracks your sleep, but ofcourse to get that info you have to do the same thing, place ear buds back in case, open and close with app open, then you can see the sleep progress. You cant just wake up to see the app and how you did. This product has great opportunities ahead of it but surely feels like is a new launch of a product. Ill wait to they make a new version and hope to see improvements listed and will surely invest.

I’ll be honest and say I’m not sure this item is strictly necessary given the already high quality of the Ozlo buds’ charging case. However, if cases are your thing, and you’re going to be travelling a lot, you might find this worthwhile. It will undoubtedly protect your sleep buds case from damage, allowing you to toss it into a bag and not have to worry about what else is in there. It also has a useful internal pouch for holding a charging cable, which is a thoughtful feature and it looks very smart.

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.

As someone who sleeps with air buds in my ears every night, I've been on the quest for great sleep buds for years. I've been switching between my apple air pods which hurt my ears often, and a raft of different cheaper sleep buds from Amazon and other online stores. I was reluctant to drop $399 on these Ozlo sleepbuds, but after ready positive review after positive review I bit the bullet. Only only two days in, but I can confirm that they are the best sleep buds I've owned (and I've owned many) - and the first that actually last all night long with battery life! They're comfortable for side sleeping and really do cut out the outside world. So far they are a total win.

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

Finally! I get insomnia frequently so I listen to sleep stories to help relax me but usually 15 minutes in, my headphones or earbuds just start hurting so I need to shut it down. The headband ones are hot and annoying on the head, not to mention the sound is horrid and you risk an uncertified battery on both sides of your head…enter OZLO, the sleep buds. Expensive? Hell yes, but soooo comfortable (fyi this is Bose tech). The sound is good and the sound that plays after your personal audiobook is done etc is adjusted separately so it can be lower or higher than the sound from your personal programs. I really don’t feel them in my ear. I highly recommend.
