Ozlo - Sleepbuds – Snore-Blocking, Science-Backed Bluetooth Earbuds for Deep Sleep and Side-Sleeper Comfort - White

I’ve been genuinely impressed with these Ozlo earbuds. The sound signature is confident and well-balanced—clear vocals, detailed mids, and a low end that’s present without drowning everything else out. They’re comfortable enough for long sessions, and the fit feels secure without that “pressure” sensation some earbuds create. Connectivity has been stable, and the overall experience feels polished, intentional, and premium. If you want everyday earbuds that sound refined and simply work, these are an easy recommendation.

Pros: Nice sound quality Small, easy to fit in your ears, and they don’t fall out Great battery life Earbuds fit easily in the case, and are easy to place even in the dark Decent app Large selection of sounds Sounds are downloaded to plenty of memory in earbuds allowing operation without the case Helps you stop snoring (for whatever reason) Cons: Finicky to get it paired and connected Too many required steps and conditions to do anything with them Battery charge indicators hidden when case is closed Most sounds sound like white noise It takes too long to download the sounds to the earbuds and can’t use or wear them while downloading Snooze button does not work Build Quality: The earbuds feel high quality and well made, although the case feels a little less durable and flimsy. The earbuds fit in the case using a magnet and fit well, so well that they can be placed in the case in a completely dark room without a problem. Battery: The earbuds have excellent battery life. At 50% volume, I can get around 10.5 hours of use, plenty for a full night’s sleep. The case can charge the earbuds around three times, and it takes around an hour to fully charge the case and earbuds together. The batteries are probably the most impressive part of the system. Fit: The earbuds fit well in the ears although I do find them hard to get in initially. I’m able to get them in and stay in but not how they recommend in the directions. It’s kind of an annoying experience but that may just be me. They are small enough to allow you to sleep on your side without pain or them falling out. They come with different size tips, but my experience has been the same with all of them. The fit is snug and completely blocks most but the loudest sounds. Sounds: There are a few dozen sounds to select from of all different types, but I have found that most of them sound like variations of white noise. There are a few that don’t and those are ones I use. My favorites are jungle and ocean. I wish that thunderstorms sounded good, but that is one of the once that sound just like white noise. In general, they have good sound quality for what they are supposed to be used for. The sounds are selected from the app which allows you to preview the sounds before selecting them. Once selected, you can download them to the earbuds themselves. Unfortunately, they must be placed in the case to download them which means you can’t use them or even have them placed in your ears. That also means you can’t really download sounds while you are in bed. It also takes around 10 minutes to download each sound which is way too long. All this means is you really need to plan ahead when you want to use a different sound. Lucky, there is enough memory in the earbuds to download plenty sounds. Case: The case seems a little flimsy but gets the job done and the earbuds have a good fit in it. While the earbuds can play the currently selected sound without the case, you need the case to do things like change the sound, change the volume, download new sounds, and charge the earbuds. The case has a system where when you open it, it boots up the firmware in the case and connects to your phone. When you close it, it turns off the case. If you want to do anything that requires the app, the case must be opened and connected to your phone. The case charges via usb-c port. There are indicators that tell you that the case and earbuds are charging, but the case must be open to see them. It would be nice if they were visible all the time. Earbuds: They fit well in your ears although it is hard to initially get in based on the directions. They fit well when sleeping on your side and stay put. The connection between them and the case is reliable. They block out almost all sounds when the earbuds are worn, but playing sounds blocks out all outside noise, including talking. There are no buttons on the earbuds so you must use the app and case to do almost everything. Connections: Bluetooth connection to your phone is where things start to fall apart. Connection to the case is required for the phone to communicate to the earbuds. The connection between the case and the earbuds is reliable, but the connection from the phone to the case is not. I installed the app and followed the steps to connect the phone to the case, but it just would not connect. I tried several times until it finally worked. When you start the app, you must make sure the case is open and booted up before the phone can connect to it. This connection was extremely unreliable. I did get a new phone a couple of days after getting this to work. Again, it was painful to get the new phone paired with the case, only this time it seemed worse. I tried several times to get it to pair, and it was only after installing the app a couple of times that I could get it to work. I updated the firmware, and it seemed to make the connection from the app to the case a lot more reliable. Every time you open the app, or open the case, you must make this connection again which does take a few seconds, time that is noticeable. One more thing to keep in mind is that the phone connects to the case via Bluetooth and the case connects to the earbuds via Bluetooth LE. There is no direct connection from the phone to the earbuds. If any of these connections don’t work reliably, everything falls apart. Alarm: There is an alarm that you can set through the app. It will play piano sounds when the alarm goes off, and loud. They claim it is a gentle alarm, but it is not. The piano sounds just play at full volume as soon as the alarm goes off (again not gentle). Supposedly you can change the alarm sounds but I haven’t found a way yet. And here is the biggest flaw of the whole thing. There is no way to easily snooze the alarm. You are supposed to tap the case to snooze the alarm but no matter how many times I tried it, it did not work. The only way I was able to figure out how to snooze the alarm was to pick up my phone, unlock it, and click the snooze button. Those steps are the last thing I want to do when I want to snooze the alarm. Lucky the app is open, and you don’t have to open and connect it as well. This is the biggest bummer, except that I now get out of bed right away without snoozing which may be for the best. Snoring: My wife claims that I snore way less when wearing these, and she won’t let me in bed without them. That is something I can’t explain. Finally: Overall, these are worth the investment, even at the high price, especially if you like to hear sounds like nature and water when you are trying to fall asleep. When they work, they work well, but there are sometimes too many steps and conditions to do anything, such as sometimes having the case open, or closed and sometimes having the earbuds docked, or not. You do have to have a lot of patience with them, so keep that in mind. You also must update the firmware to fix a lot of reliability issues. This is mandatory. They will play your default sound when you just put them in your ears, but doing anything else beyond that requires the case and app which can be finicky. There are plenty of sounds but only a few makes sense. You also must use the app to do almost everything. You must use the sounds as just putting them in your ears to block out outside noise with no sounds, while works ok, does not make sense. Finally, I really wish the snooze button on the case worked.

Before you use, update the software. My rating is based on my first experiences using these prior to the update. And even a week later I’m still not sure these are ready for prime time without some major (to me) tweaks. The design of the buds and case are beautifully done. The buds are comfortable and come with multiple size ear tips which is great. They are tiny and so they fit and are nestled perfectly within the ear. I didn’t experience ear fatigue. The sliding feature of the case is very nice and smooth. Even my 8 yr old commented on how beautiful the color was and how cool they are to open. But for me that’s where the joy stopped. First use: the connection was extremely spotty even though the case and phone was practically glued to me. The sound would pick up microseconds faster in one bud from the next, which was confusing. It performed that way for both the native sleep sounds and other media. As far as its connectivity, it worked well for its native included sounds but if listening to anything outside of the Ozlo app it was a pain. It would constantly disconnect and I would have to remove the buds place them back into the case, close case and reopen to have them reconnect again. Try doing that multiple times in the span of 10 minutes. You get to the point where you’re over it quickly. After update: The update stated it was fixing connectivity issues. The sound greatly improved. The connectivity to videos and sounds outside of the Ozlo app was much more improved. Tolerable and worked as it should’ve from when I removed them from its packaging. Fewer disconnects. In fact, I don’t think it disconnected after the update. Yes, I understand that these are for sleeping, however, you are able to use them to listen to other media outside of the Ozlo sleeping sounds. Unlike other buds you have to restart them while in their case for everything. If you have them out and want to turn them on, you have to reset them which means placing them back into their case, closing it and opening it again. But once they connect and even if you place them into their case until you need them they are still connected to your device, which means that you’ll start watching or trying to listen to other media and begin to wonder why you can’t hear it. The buds do not auto disconnect once placed back into case. You’ll hear the buds playing the media while in the case, even when you don’t want them to. So you’ll have to manually disconnect from device Bluetooth, which is quite annoying. Also, it’s not as simple as opening up the case and the buds work (auto connect) because you have to go into the Ozlo app to connect them every darn time, which is also annoying. Once we do initial setup we should be able to open case, place in ear and it connects and once we remove them and place back into case they should disconnect. So the app…Well you can’t do much inside of the app unless you connect the buds first. Other than that you can look through the sleep sounds that they offer without them being connected. But you can’t download new sounds to the app if buds aren’t connected…again a bit annoying. I don’t see why the buds need to be connected to download sounds directly or locally to the app, when the sounds aren’t stored in the buds. The buds are supposed to be able to give you sleep data but that isn’t available yet and it states “coming soon”. They also are beta testing the buds sensing when you fall asleep so it switches from whatever media you may be listening to or if you aren’t listening to anything it is supposed to switch to your preselected sleep sounds automatically. I did select that option to test it, but I’m really unsure if it worked. So I’ll say that they haven’t perfected that as yet. Again it’s in beta. The app offers the option to set an alarm but if you have the volume set low in the app, the alarm goes off at the same level, which I understand, I wouldn’t want sounds blaring in my ear to cause damage but it didn’t wake me up at all. I will say that I like the alarm sounds. The alarm sounds are not jarring like what options you may have on your phone. They are cute gentle sounds that keep you blissfully asleep. The buds have no controls, so everything must be done locally in the app. You also can’t adjust the volume outside of the app. Which is good and another way to protect your hearing incase you fall asleep. The buds can’t be too far from the case and the case can’t be too far from your phone. The moment you step one foot past the range it becomes staticky and begins losing connection, so stay close folks. Don’t get up for a glass of water in the middle of the night or else you’ll have to reconnect. Granted, I’m still trying to get comfortable sleeping the whole night through with them in my ear. I would find myself waking in the middle of the night to remove them. Not because they were uncomfortable. They are very comfortable in my ear. I believe I was just aware that something was in my ear and even in sleep I subconsciously would be aware and nervous about my hearing even though I never had the volume above 20. So, I’m also a work in progress in being 100% comfortable going all night with sounds. My initial experience wasn’t the best and because many of the features are still in beta or coming soon, I wouldn’t be able to recommend to a friend. I really appreciate the update as it did fix my initial gripes and I fully expect that as the updates continue to improve the experience I would then be able to tell everyone to get a pair. As of today, not so much.

I’ve always been a light sleeper, even the dog moving around wakes me up at night. Not to mention all the noise or a neighbor having a party a couple of houses over. I always have a pair of safety earplugs next to the bed, those neon orange ones that are super soft, just in case I wake up in the middle of night and cannot fall back to bed for one reason or another. I was considering a white noise machine, but wanted something a bit easier to carry with and wouldn’t disrupt anyone else. That’s when I saw the Ozlo Sleepbuds, which not only streamed audio but provided background noise. So, I got a pair to try. Pros: - Very comfy earbuds. - Sounds are relaxing and customizable. - Multiple Eartips for perfect fit. Cons: - Connecting and updates takes a bit. - Comfort in ear will depend on your pillow and position while sleeping. Setup: The setup was simple; download the app, then pair to the case and then to the earbuds. You have to pair to the case to setup, but after that unless you’re going to stream audio from your phone or update the sounds, you don’t need to connect your phone to the buds each time. The initial setup will walk you through the first time to select your preferred background sound and set the few options available for how it triggers and your morning alarm. It’s very simple and takes only about 5 minutes after all the updates. Connecting: I usually watch a show or listen to something before falling to sleep so I’ve been connecting my phone each night before going to bed. I did notice that it usually took 45 seconds to a minute for my phone to connect to the earbuds each night, which is much longer than normal earbuds. I assume this has to do with the connecting to the case, then earbuds but I always catch myself wondering if something is going wrong waiting for the earbuds to connect. You’ll see a reminder multiple times to keep your phone 30ft from your smart case and your earbuds 10ft from the smart case, because of the tethering between phone to case to ear buds the distance is much shorter than most earbuds. This isn’t much of an issue unless you are getting up in the middle of the night to use the bathroom or go check on another room. I’ve lost connection a few times, but each time, the earbuds reconnect as soon as I get back into range with the case. Software: The Ozlo app is easy to use. Ozlo has been updating the app regularly, I’ve already seen an update come through that included more sounds and a soon to come feature to help you track your sleep. I found that I’m using the app regularly as I get used to the earbuds to adjust the sound and volume of the sleep noises. I also check out the new options that are available. The main page of the app provides you with all the controls to check battery life, current sleep sound, and volume right at the top. Below are the settings selected during initial setup, that can be adjusted anytime like Alarm, Sleep Timer, Auto-Play Sleep Sound (enable this!). The Auto-Play Sleep Sound is a great feature that automatically switches over from streaming your phone audio to the Sleep Sound once it detects that you’ve fallen to sleep. I’ve found it works well, usually triggering right after I start to drift off to sleep, which helps when I forget to stop what I was playing before I fall asleep. Fit & Feel: The earbuds are very comfortable, the silicone tips/wings make the Ozlo SleepBuds some of the most comfortable earbuds I’ve ever had. 4 sizes are included, 1 on the earbuds and 3 in the box to ensure you get the best fit possible. I did find the default tip was a bit too small, which let in additional noise while sleeping and allowed the buds to shift out of my ear the first night. But with the larger tip, I’ve not had any issues with the earbuds falling out. You can barely feel these in your ear in the beginning of the night. The only issue with feel I had was the next morning, as I usually sleep on a firmer memory foam pillow, which depending on how I lay my ear ends up as the main point of contact with the pillow. Which unfortunately pushed the earbud against the side of my inner ear, causing discomfort after long periods. When I woke up in the morning I had a sore ear, along with an indent in my ear. If you’re a back sleeper or using a softer pillow, you won’t even notice. But if you are using a firmer pillow, you might need to shift or switch pillows. I ended up switching to another pillow with a shape to it, where my neck and head get better support, and my ear isn’t the main point of contact. That solved the discomfort! Sleep quality: I did find the Ozlo Sleepbuds helped improve my sleep mainly by reducing the number of times per night that I would wake up due to a noise, though I would put them on the same level as my old safety earplugs there. They were much more comfortable than the earplugs, which block-out almost all sound and put pressure on my eardrum and inner ear. I can only wear the earplugs a few nights in a row before I need to not wear them, that was not the case with the Ozlo Sleepbuds after I swapped out my pillow. I look forward to the future feature that tracks your sleep, as I use my watch right now which is good, but I would like to have another measure of sleep quality to compare it to and see if there are any different suggestions besides “sleep more”. Alarm: The alarm is also a big part of the benefit of the Ozlo Sleepbuds, as it can be an issue when sleeping with earplugs to hear your alarm unless you have it blasting or shaking your bed. I’ve missed my alarm more than once because of having earplugs in. The Ozlo alarm comes with different sounds and nicely alerts you that it is time to wake up, though if you need one that shocks you awake there is a “Wake Up!” alarm sound that is reminiscent of the old alarm clocks. Sound Options: I found the different sleep sounds to be very calming, I mainly used the Fireglow and Soar as both gave me a warm but calming sound. There are a lot of options to pick from and Ozlo is adding more. I liked the consistency of all the sounds, being pleasant and constant background noises. I was going to suggest that they include some kind of city or road sound, but then with the last update I saw they had added an Interstate and All Aboard soundscape that mimics a highway and train. I was thinking these would be very helpful for anyone who lived in a city or populated area, when going on a trip to somewhere much quieter like camping in the woods or a lake house. As the transition from noisy night life to quiet night can be a shocker for many, so having the familiar background would allow them to sleep better. Conclusion: I really like the Ozlo Sleepbuds, as I’ve used earplugs for years to help manage my sleep due to how easily I wake up from any sudden noise. The earbuds are very comfortable and can be adjusted to fit almost any ear snuggly. Plus, with the variety of calming sounds, you’ll be able to find one that soothes you to sleep and helps keep you asleep. Just beware if you’re a side sleeper using a firm memory foam pillow, you might want to swap out your pillow or adjust how you lay on it. I’ll be adding the Ozlo Sleepbuds to my recommendations for anyone who is a light sleeper that wants a better way to sleep and wake up.

Bottom Line: These earbuds are a paradox. For a staggering $350, you get some of the worst Bluetooth performance I've seen in years. However, you also get incredible comfort, fantastic sound quality, and a truly transformative sleep experience. If you are a desperate light sleeper like me, the pros might just outweigh the frustrating cons. Pros: • Exceptional passive noise isolation blocks out most disturbances. • Extremely comfortable and small, making them suitable for side-sleepers. • Surprisingly fantastic audio quality for listening to music. • Long earbud battery life (lasts the whole night). • Premium look and feel of the case and earbuds. • Genuinely and measurably improved my sleep quality. Cons: • Bluetooth connection is unreliable and frustratingly slow. • Transferring new sounds to the earbuds takes an eternity (10-20 minutes per sound). • Very expensive for a limited feature set (no ANC, no multi-point). • Charging case is bulky and not designed for travel. • The built-in "soundscapes" are repetitive and low quality. • Can cause some minor ear soreness by morning. Bluetooth Performance (3/10): Let's get this out of the way: the Bluetooth connection is horrendous. It feels like first-generation technology. The earbuds connect to the case, which then connects to your phone, creating a weak and finicky link. Constant Issues: Nearly every night, I have to put the buds back in the case and reopen it to force them to connect properly. Painfully Slow Transfers: Adding a new soundscape is done over this slow connection and takes 10-20 minutes PER sound. In 2025, a $350 device should have Wi-Fi for this. It's unacceptable. The Case (7.5/10): The case is a premium, hefty puck made of a metal alloy. It feels substantial and looks great on a nightstand, which is where it's meant to live—it is far too large to be considered portable. The sliding mechanism is neat, and magnets snap the earbuds securely into place for charging. It provides 2-3 full nights of charge before needing to be plugged in via USB-C. Earbuds & Noise Isolation (9/10): The earbuds themselves are the stars. They are tiny and feature incredibly soft silicone tips, making them more comfortable than any other earbud I've tried for sleeping. They achieve their silence through excellent passive noise isolation, meaning they create a physical seal in your ear. This works incredibly well to block out sounds like roommates walking around. (Note: Because they seal your ear, be cautious about moisture after a shower to avoid potential ear infections). They smartly do NOT have Active Noise Cancelling (ANC). With ANC, microphones would pick up every rustle against your pillow, likely causing screeching or other audio artifacts. Opting for a great physical seal was the right engineering choice. Sound Quality (9/10): Here, it's a tale of two experiences. Music: I was shocked at how good music sounds. The bass, mids, and treble are all well-balanced, creating a rich and enjoyable listening experience before bed. Built-in Sounds: The pre-loaded "soundscapes" are a letdown. They sound like short, obvious loops, and the stock sounds on my phone are of higher quality. For the price, I expected much more variety and higher-fidelity background noises. Battery Life (7.5/10): The earbuds deliver on their 10-hour promise. I sleep for 7-9 hours, and they are always still playing when I wake up. The case provides about 3-4 nights of use before it needs a recharge, which takes a slow 2-3 hours. It's adequate for home use but would require planning for a trip longer than a weekend. Conclusion: Who Is This For? I desperately wanted to love these without reservation. As a light sleeper, my sleep quality has been chronically poor. With these, I am no longer woken up by small noises. My smartwatch shows my "time awake" during the night has dropped by roughly 75%. I feel more rested and have more energy during the day. And that is the ultimate selling point. What would you pay for a better night's sleep? Despite the infuriating Bluetooth issues, the difficulty in transferring sounds, and the high price, the core function works so well that it's almost worth it. If you are a light sleeper at your wit's end—and you have the budget and the patience to wrestle with the technology—these could honestly change your life. However, if you expect a seamless, modern tech experience for your $350, look elsewhere. I'm torn, but for now, the benefits of better sleep are keeping them on my nightstand.
