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.]

Good initial impression...will update review after more use...
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.

Comfortable earbuds that help me sleep, but they do have some drawbacks...
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.

Restorative, restful sleep inbound
I was an avid user of sleep buds by Bose, but little did I know, they were discontinued. I panicked when my buds died, but luckily, I saw these available and decided to give them a try. They were quite expensive, which I was apprehensive about, but my quality of sleep is worth the investment. My husband snores, badly. It interrupts my sleep AND his sleep because I'm constantly having to wake him up to turn over. On top of that, I'm a very light sleeper. First of all, I've been using these for about a year now, and I'm loving them. The battery life is sufficient, and the manual states that leaving them plugged in will not harm the case battery, which is also nice. So it sits on my bedside plugged in at all times. I've never had the earbuds die during the night. Just make sure you double check that both lights are blinking when you place the buds back into the case and you'll be good to go. They fit comfortably in my ear. The only problem I've had with it is that sometimes, if my head is positioned a certain way on my pillow when lying on my side, it cancels out the sound. I assume it's because there's too much pressure. That drives me crazy sometimes. I really love the option to be able to watch videos and hear the sound. This was not something the Bose sleepbuds offered. I doubt that this is what it was intended for, but I like to watch a few videos before going to sleep. I just set it to "When I Fall Asleep" which typically gives me about 30 minutes before the white noise sounds begin. It's my signal to go to bed :) There's a really nice selection of sounds to choose from as well. I personally like Rainfall, Crimson Cloak, and Warm Glow, they feel the most "white-noisey" to me. You can adjust the volume based on how you like it. When I am alone, I keep the volume lower, enough so that I can hear if something/someone is near me. But with a snoring husband next to me, I keep it at medium volume, which is plenty. These sleepbuds have given me restful sleep, something I've lacked for so long. I honestly can't imagine not having them. I hope they are never discontinued! They're superior to the Bose sleepbuds by far.

Effectively $300 Ear Plugs
*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.

It took me 3 days to figure them out but……
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.

Avoid Ozlo = poor design - unreliable - over priced Lipstick on a Pig
Why Bose ended the Sleepbuds line—both the first-gen (2018–2019) and Sleepbuds II (2020–2023). What sank the original Sleepbuds (2019) Unreliable silver-zinc micro-batteries. Bose publicly said the batteries “didn’t work as consistently or predictably as they should,” and discontinued the product while offering refunds. Multiple reports tie this to the chosen silver-zinc cell chemistry; Bose’s own launch materials confirm that chemistry. Not a safety recall, but a reliability retreat. Bose emphasized there was no safety hazard and continued warranty/replacement support, but the erratic charge/early shutdown behavior was widespread enough to pull the product. Why Sleepbuds II ended (2023) Limited mainstream adoption even after a redesign. Bose says plainly that Sleepbuds (including II) “did not reach the level of adoption we hoped.” That is Bose’s official reason for ending the line and the companion Sleep app. Bose Support Strategic focus. Reporting at the time framed it as Bose refocusing on core categories (headphones, speakers, ANC) after a niche product failed to scale. Design constraints made them niche. By design, Sleepbuds II couldn’t stream your own audio (they only played built-in masking tracks from the Bose Sleep app), which limited appeal next to multipurpose earbuds. Retail pages and reviews called this out. Supplier/chemistry headwinds for Gen 1. Industry notes around the time point to turmoil in silver-zinc suppliers (e.g., ZPower in hearing-aid markets). While Bose didn’t name a supplier, the chemistry choice is documented and aligns with the reliability issues Bose cited. (Inference based on silver-zinc use and contemporaneous supplier problems.) The concept was revived by ex-Bose engineers as “Ozlo Sleepbuds.” Three former Bose employees acquired the Sleepbuds trademark/technology and relaunched the idea with added capabilities (e.g., streaming your own audio, sleep-triggered auto-switch to masking). Rivals kept adding features Sleepbuds II lacked. Anker/Soundcore’s sleep earbuds line moved toward ANC, streaming, private alarms, and sleep tracking—features broad audiences expect—while staying comfortable for side sleeping. That raises the bar for adoption if your product is single-purpose. Gen 1 died from battery reliability. Gen 2 died from business reality: even improved hardware couldn’t overcome a narrow use case and rising competition, so Bose redeployed resources to bigger categories. Ozlo’s version retains the same general design for sleep-use, but adds more flexibility (ability to stream your own audio, biometric sensors, etc.). No improvement to battery life - left bud will fail - requires constant charging - when new battery charge after 7 hours = 1-2% Ozlo is a failed discontinued Bose product poorly resurrected by Ozlo - over priced - extremely poor battery life and as others noted - the left bud will FAIL in a new short months - I had to return/exchange two pairs. Update - the charging case will go dead very very quickly if NOT connected to a charger - other brands do not loose their charge if not connected to a charger as quickly as Ozlo both the buds and charging case do not retain charge Cons - Extremely poor battery life in both the buds and charger - the case does NOT retain a charge unless plugged in Left bud will loose audio level within weeks - Ozlo replies you need to clean the ear piece then why do other brands not have this problem - it's not the cleaning - it's a bad product Poor Audio quality Extremely poor battery life - at the end of 6-8 hours you might have 1-2% battery level Poor connection issues - difficult to connect to blue tooth - connectivity is unreliable Horrible software - brain dead software - lack of features - features built in = useless Value - if Ozlo was priced at 50.00 it would be a decent value - at 300.00 Ozlo is a rip off a very poor investment Pros - the ONLY redeeming factor is the fit - Ozlo although offers a terrible selection of ear bud sizes but Ozlo does fit well
