Ozlo 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. 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 wanted to give these a solid month before writing my review. I have been using Bose sleep buds since the first edition in 2019. They were always a bit "wonky" The left bud always died first... I ended up purchasing a second pair, and would swap them out as the battery died. I have been watching Ozlo since they were in the money raise phase. After reading so many negative reviews, I could not justify spending the "ridiculous amount of money" for them. I finally tried the Anker Sleepcore 30's. I sent them back after 3 days. They were awful. Not sure if it was user error, but I spent more time awake at night trying to reconnect and adjusting settings, I gave up and went back to the Bose. Now that Bose is no longer updating their app, connectivity has been a nightmare.... and I finally broke, and bought these on sale. I wish I would gave done it sooner. The battery lasts far longer than the promised 10hrs. Keep in mind, I use these only for sleep and in power save mode... so I cannot attest to the battery if you're using them for the bluetooth options. They fit so comfortably (the Bose were starting to hurt the inside of my ear) I'm an "all over the place" sleeper.. both sides, my back and even face planted on my man.... They don't irritate me at all, and I have sensitive ears. Now for the real magic.... The snore activated masking. For the first few weeks, I was sleeping alone.... the last two weeks, I have had a snoring partner next to me. These are far superior for blocking snoring than my Bose ever were. I sleep soundly, through the night.... and it's fun to download your sleep data and see how many "noises" (snores) you were shielded from. :-p

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.

I got these headphones just a few days ago so my review is based on only a few days of usage and I will update the review once I have had more time to use them. However, so far they are looking pretty solid -- I was a little scared from reading other reviews where people had lots of issues while setting them up. Maybe those issues have been fixed in the recent versions of these devices. App installation, pairing, firmware updates, adding sleep sounds, setting up alarms, charging, etc. everything worked without a hitch. My favorite part so far is that Ozlo does not force you to create an account with them in order to use the sleepbuds. Too many devices now-a-days refuse to work without creating an account first. With Ozlo Sleepbuds, this is completely optional and you can use them indefinitely without creating another account that exposes you to potential privacy issues. Let us hope that Ozlo does not change this in the future. The headphones are very comfortable for me to wear while sleeping and are great at noise cancellation. I also really like the alarm feature (the phone's built-in alarms do not work with the headphones and I think I know why). The only annoyance so far has been that I have to leave the headphones in the charging case in order for the android app to connect to them. In other words, I have the tendency to take them out of the case, put them, and expect them to be able to connect to the app automatically since they have already been paired. This is how all other Bluetooth headphones work. Alas, this does not work with the sleepbuds. So then I remember that they need to be in the case to connect to the app and have to take them off again. I am guessing I will get used to it over time.

*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.

These sleepbuds are exactly what I was looking for. Great for side sleeping, they are comfortable. Fast charging. If you are looking for sleepbuds that last all night, buy these. They have lasted every night for 8+ hours using the prerecorded library. The crimson cloak sounds, sounds like white noise. Fabulous! I have bought other brands and these are amazing. By far my favorite! They do block out a snoring husband. Game changer! The only negative, you have to transfer your sleep score every morning. I wish it would do that automatically. With that being said, I would definitely repurchase these again when these no longer work. Buy these, you will not regret it! ,

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.
