Customer Ratings & Reviews

I had been a user of the Bose Sleepbuds so jumped on the chance to get these. The biggest shortcomings to the original Bose were bad connectivity (one earbud would suddenly stop working in the middle of the night) and inability to stream my own music or audiobooks. These Ozlo Sleepbuds 2 solve both issues. One critical technology that was not available when the Bose Sleepbuds were around was Bluetooth LE Audio. This form of Bluetooth allows streaming of audio (not just data) over a low energy wireless connection. And this is the part of the magic that lets Ozlo stream your own audio. The case not only charges, but also serves as a wireless bridge. Your phone streams personal audio to the case using regular Bluetooth. And the case then streams it to the sleepbuds using Bluetooth LE Audio. Unlike regular Bluetooth, not all phones support Bluetooth LE Audio. By using the case as a bridge, it ensures wider compatibility with smartphones. PROs • Very comfortable for me as a side sleeper. Some minor adjusting is required from time to time, but as long as your pillow is soft enough, it’s easier to wear these all night than foam ear plugs. • I can stream my own music and audiobooks from any app. Librivox, Kindle and Calm, for example, have a great libraries of audiobooks that are just engaging enough to distract you from your own thoughts, but boring enough to lull you to sleep. • When listening to your own audio stream, you have several options of what happens when your audio stream ends (such as end of playlist, audiobook, timer, etc…). One notable option is that if you fall asleep listening to your own stream, the sleepbuds detect you’ve fallen asleep and will switch to the local sound you’ve selected. This lessens the chances that you will wake up due to a change in volume later when your audio streams ends, though I do wish there was a crossfade option to make it more seamless. • The extra tips are nicely labeled so you don’t have to guess the size, especially once they are out of the bag and you’re trying different ones for fit. • The biggest impact these sleepbuds have had on me is that I can finally listen to my own audio without disturbing my wife. Even if we agree on what to listen to over my phone’s speakerphone, the rustling of the sheets means I miss some of the audio. These sleepbuds ensure choice and continuity in what I’m listening to. CONs • Like the Bose, these are sound masking, not sound blocking. Loud noises like a snoring partner, sirens, etc… are still likely to wake you. But background noises like tend to get lost in whatever you’re listening to. • When listening to your own audio stream, you can use your phone’s buttons to adjust volume. But when listening to Ozlo’s sounds that are transferred to your sleepbuds, you have to use the Ozlo app to adjust the volume. So you better make sure it’s set to your desired volume before you go to sleep. Interestingly, the case has a button that acts like a play/pause if you don’t want to open the app. I wish they had included volume buttons on the case as well. But I really hope they redo this bit of software in a future release since it’s so natural to use the phone’s buttons. • Because the case is a wireless bridge between the phone and sleepbuds, it must be kept within ten feet of the earbuds to stream your own audio. This means you can’t walk around wearing the sleepbuds unless you take the case with you. If you are using one of Ozlo’s sounds that were transferred to your sleepbuds (”local sound”), the case does not need to be kept near you. • The sound lacks bass, especially when comparing them to regular earbuds. It’s not a big deal for sleeping purposes, but it can throw you off the first time you try them and are expecting them to sound as good as a pair of Bose QC, AirPods or such. That said, the sound has good clarity and works well for spoken word audio. OTHER The sleepbuds can track your sleep and give you data on how well you slept. My watch also does this but Ozlo gives more detailed tracking data, especially because the case also monitors the environment. After tracking my sleep for a while now, I find the data interesting but not necessarily useful. I know when I’ve slept well and when I haven’t without needing a device to tell me. If you have trouble sleeping because of loud noises in your environment (snoring, trains, pets, etc…), these sleepbuds will not magically make those noises disappear. But they are great for anyone who wants to listen to their own audio to fall asleep without disturbing their partner.

A sleep-enhancing and monitoring system incorporating comfortable, light-weight earbuds that are customized for side-sleepers and optimized for delivering compatible audio for sleep. Who - Several former engineers and principals from Bose, the well-known pioneer of sound products in the Boston, MA area created a company to further the goals of the now discontinued, Bose Sleepbuds. With a wide variety of expertise and the licensed and highly-valued IP mostly from Bose, Ozlo was created to transform the Sleepbuds concept to a more sophisticated, effective tool for consumers to sleep better and interpret sleep patterns detected through technological advancements. What - Sleepbuds 2 arrive in sumptuous packaging that imparts a feeling of indulgence. Central to the system, is a round case that slides open to reveal the Sleepbuds wearing a pair of the four included sizes of custom silicone tips. Upon opening, there are several status lights that indicate the state of charge of the base and the communication status to the Sleepbuds 2. The case is designed in such a way as to be unobtrusive sitting on a bedside table and effortless to access prior to dreamland. Accompanying the case and the extra silicone tips is a USB-C to USB-C cable that comes free to insert into any of your previously-owned chargers, as none are included. The Sleepbuds 2 are designed to have a very slim profile that fits within the pinna’s conchal bowl that allows for comfortable side-sleeping. When the silicon tip size is selected correctly, it fits very well and provides a good mechanical seal, helping to isolate from external sound, staying in place throughout the night and providing the most accurate lower frequency reproduction. The Sleepbuds 2 partner with a very attractive and sophisticated-looking app that allows for a number of sounds to be selected from and downloaded into the Sleepbuds. Some of the sounds are typically-expected nature sounds perhaps synthesized, but certainly blended with masking sounds like white, pink or brown noise that all have unique spectral balances. One sound called “Dream”, that I’ve listened to for several nights now, evokes a sort of audiologist’s Rorschach test of a combination of what sounds like brown noise (lower frequency hiss) combined with distant and low volume inclement weather warning sirens that fade in and out. Kind of hinted at what it might sound like to be in the lobby of purgatory. Happy dreams? There are plenty of other choices. Some of the sounds are free and others require payment. The quality of the recording engineering is top-notch in my humble opinion. There are no poor looping-edits noticeable. Audio quality is high throughout with an active stereo sound-stage present in most everything I listened to. Also, no abrupt dynamic range changes to startle you. When - Ozlo has been in business independently starting from about 2022 with much of the work on the Sleepbuds 2 starting in about 2025. The Sleepbuds 2 are the supposed culmination of a number of customer-driven suggestions and refinements based on the strengths of the original Sleepbuds. Where – Based in the Boston area for the research and development aspects and ultimately manufactured in China. How - The all-important how is where the magic happens. Through the knowledge applied from all those patents and the microelectronics that yield approximately 14 hours of playback with some usage of a Bluetooth connection and at only about 1.6 grams of weight for each earbud, this hardware and the app software collaborate to identify your sleep patterns and promote better sleep by blocking external disruptive noise and by attempting to calm the mind while getting to sleep. It will be up to you to determine what sounds you find the most effective at doing so and at what volume level you are comfortable with. There is a balance to determine between being in communication with the external physical aural world and being nearly totally isolated from it. For those who feel a need to make a transition into dreamland from conventional content, these earbuds can be streamed to with non-sleep-inducing content and then seamlessly redirected to the sleep-supporting content from the app at the moment the system detects that you have fallen asleep. Other derivatives of similar functions can be selected from the app. In my experience, I found that a little lower volume was actually helpful to alleviate concerns of being too isolated, yet just enough to separate from the mundane noises that might be a distraction from falling and staying asleep. Another feature is the ability within the app of selecting to isolate your sleep from the phone’s distracting messaging, notifications, calls, etc. There are also a number of different alarm noises that you can choose to give you notice that it is time to rejoin the world. Also helpful are the sleep trends section in the app that accumulate and compare your duration of sleep, quantity of awakenings, your duration goal averages, consistency goal, efficiency goals, noise events that could have disrupted your sleep, light in the room while sleeping and your reported feeling of your night’s sleep’s effect upon waking. Conclusion – I would recommend this product to those that have noises to overcome and might require a little help with getting to and maintaining sleep. This product is by no means a panacea for all, but might assist if you need some sleep-detective investigation of the timeline and depth of your sleep that you probably wouldn’t necessarily know without a little help. The upload of data from the Sleepbuds 2 once they are removed from your ears and placed back in their case in the morning is sometimes problematic. It occasionally takes me multiple attempts to get the sleep data to upload to the app on the phone, where it can then be observed. Hopefully that can be improved upon and may be just my phone and it’s settings, but it is by no means a deal-breaker.

The Ozlo Sleepbuds rely on isolating outside sounds by using their unique fit and masking soundscapes which are played via the mobile app. While I found them comfortable to wear I did not feel like they would be very helpful in eliminating the sounds of someone snoring in the same bed or traffic noises from a busy street. They do mask some of the sound but I would not recommend them as a sound isolating device. They are however useful in helping to lure you into a relaxed state for sleep. The auto sleep detect functionality and ability to capture sleep patterns to customize your personalized sleep routine does seem worthwhile. Pros: - Comfortable to use even when side sleeping - Over 50 types of soundscapes to help you drift off - App is intuitive and easy to use Cons: - Bluetooth connectivity goes through the case to the earbuds so the case has to be near the phone with the app open to work consistently - No control on the earbuds – everything including volume needs the app - Relies on masking outside sounds vs active noise cancellation - Mediocre sound quality with very limited equalizer settings Fit and Feel: I found the Sleepbuds easy to insert and the soft silicone wings hold them in place without irritating your ear. Because the earbuds do not use active noise cancellation they rely solely on the ear tips to isolate you from the outside sounds. The trade off becomes getting a tight fit to isolate the sounds without creating pressure on the ear canal. Ozlo provides 4 sized ear tips but the main difference is the length of the wings which hold them in place. I tried all four sizes and decided the best fit for me was the size two. I used my phone’s camera to see how the wing interacted with my ear to help with the choice. Because these earbuds are so small they don’t feel intrusive and are easy to use while sleeping on your side. Use: These earbuds rely solely on the silicon tip to isolate you from external noises. Even with the best fit I found that I could still hear my robot vacuum on the floor. For someone in a loud environment or next to a loud snorer I don’t believe these earbuds will have a big impact on eliminating the external noises. The earbuds combined with the included soundscapes might help mask some of the noise but that will depend on how sensitive one’s hearing is and how loud you can tolerate the earbud’s volume The included soundscapes in the app definitely help in a relaxing manner and the automatic sleep function is an interesting option. According to the app it will give you more insight into your sleep patterns over time so that you can customize your sleep routines. After each night you have to pair the earbuds in the case with your phone to upload the data. The apps shows your Awake, Rem, Core and Deep sleep along with the noise detected, temperature and light of the room. It also will show you trending information as it captures your sleeping data over time. I haven’t used these long enough to judge the accuracy of the information or compare it to other sleep detecting devices. The overall audio quality of the earbuds is fine for listening to a podcast or the soundscape sounds but its only mediocre when it comes to playing music.

I am a night owl, and falling asleep is difficult at times. I normally play thunderstorm sounds on my speakers, but I have always wanted them to sound more "present," like headphones would offer. I’ve tried to sleep with normal earbuds, but none of them work as they are too large. The Ozlo Sleepbuds 2 fill that need quite well. They are very small and designed so you can wear them while you sleep. I mostly sleep on my side, and so far, I’ve been happy with these headphones. The case is impressive and slides open & shut with a magnetic mechanism, although it would be nice if it had a lock, as it might slide open in a bag. I also think the case could be smaller, but it’s a minor quibble. As for comfort, they are about an 8/10 when lying on my side. I use a pretty firm pillow, so when I lie on my side, they push into my ear and are a little uncomfortable. They fit much better when I use a soft pillow, FYI. Also, despite trying several of the rubber fins that keep the buds in my ears, every night I used them, I woke up with both having fallen out at some point. They have some useful built-in sounds for things like masking noise and lulling you to sleep. You can also transfer the sounds you like to the earbuds themselves, which is nice if you don’t use your phone in bed. I mostly use the MyNoise app, but the built-in sounds are nice to have. It is also nice to stream anything that puts you to sleep, such as an audiobook or whatever else you want to listen to. Additionally, there is a feature called "sleep shield" that silences your phone notifications so you aren’t woken up by a 3 a.m. text. However, you cannot use them for phone calls or with a microphone, as they are listen-only. You can also set an alarm so they alert you when you want to wake up, which is useful since I’m a very heavy sleeper and would hate to miss my regular alarm because I couldn’t hear it. They also feature a sleep tracker, but I use my smartwatch for that. The case is solid and has USB-C charging. Unfortunately, it doesn’t support wireless charging, but that doesn’t surprise me. All in all, I really like them, find them comfortable, and toss them in my work bag when I travel. I haven’t yet figured out a way to keep them in my ears the whole night, but once I’m asleep, I don’t notice the difference. I definitely recommend them if you are in the market for sleep earbuds!

Trouble sleeping? Give the Ozlo Sleepbuds 2 a try. I’ve never been a good sleeper and have tried all kinds of noise machines and sleep devices. Some work better than others. These come packaged beautifully. Instructions are clear and concise and you’ll be up and running in minutes. After downloading the App, you’ll be synced up and running. Give them a full charge before your first night of sleep. Choosing different sounds was easy. There is a library to select from. Note that only so many load onto the earbuds, as there is a limit. So you’ll have to “replace” sounds. Settings was straight forward and the App overall is pretty easy to use. There are many different masking sounds to choose from. One note, the volume can only be controlled through the App, not the volume dials on your phone. I do wish the volume could be controlled by the phone as well, especially when in bed and you want to tweak the volume. You will have to open the App and do so there. As for the buds, they come with a wide variety of size inserts to fit your ears perfectly. They are comfortable when inserted and super lightweight. Now, for me, it comes down to sleeping positions. I can only sleep on my side and that’s where I have an issue. I don’t blame the buds, but the fact is when sleeping on your side, they do slightly push in your ears and it can be a slight “pain”. I’m sure some will not mind at all. For me, the pressure on my ears is slightly a “pain”. For back and stomach sleepers, these would be ideal. For side sleepers, it all depends on your tolerance level and the softness of your pillow. I find I can make it through most nights, but as a side sleeper, there are times I have to take them out due to them being irritating from the pressure of them pushing into my ears. Again, that’s just my personal experience. These can be a game changer for most. The battery life is superb and make it though the entire night with life to spare. I love the charging case as well. All the components are super well made and durable. I recommend these to give them a try. For most, they will be awesome and truly help you sleep. It is just that I’m a light sleeper and the being a side sleeper makes it a little tough for me. Overall these are an incredible product and should be tried by all looking to get a good nights sleep.

As the spouse of a loud snorer, I’m willing to try just about anything for better sleep. Earplugs fall out and feel uncomfortable, wedge pillows didn’t help, so I was hoping these Ozlo Sleepbuds would finally make a difference. Design & Setup The Ozlo case is beautifully made—aluminum with a smooth sliding cover—and the setup through the Ozlo app was straightforward. The app is easy to navigate and offers more than 50 different sounds, ranging from rain, ocean waves, and white noise to more unusual options like an idling engine or a passing train. I got a laugh out of the “soar” sound, which mimics the inside of an airplane. When I’m actually flying, I use noise canceling headphones to block that exact noise. Comfort The Sleepbuds fit my ears comfortably and sit recessed enough that I can sleep on my side. I still notice them, but they aren’t painful. I’ve only used them for a few days, so I may get more accustomed to the feel over time. A few nights, I woke up and removed them because they were bothering me. Even without playing any sound, the soft rubber tips block out roughly half of the snoring volume, which helps. Usage The Sleepbuds worked well overall. The soothing sounds helped me fall asleep several nights, and I didn’t hear my partner snoring at all. Snoring volume varies, so I can’t say whether those were particularly loud nights, but the buds definitely helped. You can also stream music and podcasts from your phone if you prefer. One minor inconvenience: although the app offers 50+ sounds, they must be uploaded to the Sleepbuds rather than streamed. Each time I chose a new sound, I had to place the buds in the case so it could transfer—about four minutes per sound. The buds can store only ten sounds at a time, so adding a new one means replacing an existing one. Overall I like these Sleepbuds more than I expected. They’re comfortable, offer a wide variety of sounds, and genuinely help reduce snoring noise. They do take some getting used to, and my ears occasionally itch after wearing them for a while. I haven’t tried the sleep tracking feature yet since I already use other devices for that.

Ozlo - Sleepbuds 2, Noise-Masking Sleep Earbuds This product became available for evaluation shao I accepted the opportunity to evaluate it. But first, let me share some reasons why this product interested me: I do have excessive hearing loss so I wear hearing aids. I also have a constant tinnitus ring, as well as the hearing loss. I also have difficulty falling to sleep and often lie awake for hours before falling to sleep. Once I do fall asleep, it is a deep sleep but doesn't last as long as I need. So now that you know this, you can understand my interest in this sleep-aid product. First off, I will say this is a high-quality product. It is delivered in a 4-inch box with the accessories included. So, the unit is a convenient size. Included are various size earpieces to suit comfort level. The system works through Bluetooth with your phone. The many sleep sounds seem extensive and though I haven't explored it yet, but also supports music, as well. The unit comes with a charging cable and a downloadable app to the phone. Put it all together and it may help make sleep more beneficial. I have two issues with this product. I wear hearing aids all day and take them out at night. To use the Sleep Buds means I would have them in at night. So that means I have something in my ears all the time. The second issue is the price. If I had to pay the price that is displayed on the Best But website, I would be hesitant to make the purchase. But again, it is an excellent, wee- thought-out product. I found no issues with how the system works. So I would have no problem recommending this product. Each person has to make a decision on how much they are willing to spend to make the purchase.

My significant other is a very light sleeper so it was an easy decision to get these Ozlo nighttime sleep buds for her. I figured it would be a win-win situation for us both if she liked them. After a few nights of use I was pleasantly surprised that not only did she like them, but that she loved them! Everything you need to use these earbuds is included in the box. Setup is easy because the App walks you through the pairing process. Once they are paired to your phone, all it takes is putting the earbuds on your ears at night and let them do their thing. Of course the App has numerous features and customization options available. The setting she mainly uses is to turn on a white noise after the earbuds senses she has fallen asleep. There are a few different sleep sounds to choose from. But even if you don’t use a sleep sound the noise cancellation capability does an excellent job of identifying and canceling out sound. The earbuds are comfortable to wear and most people will not even notice that they are there. They are comparable to earplugs in size so if you can tolerate having earplugs in you should have no problem wearing these earbuds. A great feature the Sleepbuds 2 offers is that they sense the timing and quality of your sleep. Every morning a sleep report is available for your review. The App even identifies how many times at night it blocked a noise and the decibel level of said noise! Since I game them to her, my partner has used them every night without fail. For this reason I give the Ozlo Sleepbuds 2 the highest possible recommendation.

These OZLO Sleepbuds® 2 are not my first pair of sleep buds and have to say they have come quite a ways since my first pair. The OZLO Sleepbuds® 2 case is beautiful and well made. The case can charge the sleep buds a few times before needing to be recharged. They include several different ear tip sizes help fit comfortably into your ear. I downloaded the OZLO app and paired the case and sleep buds to my phone. It was very easy to get the OZLO Sleepbuds® 2 customized to all my preferences. There are so many ways to customize the sleep buds to aide in sleep. You can listen to audiobooks, music, or masking sounds. The OZLO Sleepbuds® 2 are comfortable and do help mask my husband’s snoring and outside noise. I will say if you are a side sleeper like I am, I have noticed it can make my ears a little sore in the morning. I have not had any issues with connectivity while sleeping which I have experienced in the past with other brands of sleep buds. My preference is to use the masking sounds to keep the levels consistent throughout the night. The sleep buds have done a good job masking the sounds outside to help keep me asleep. In the morning you can upload the sleep data to the OZLO app to see how well you slept the night before. The app can help analyze your sleep patterns to help improve the quality of your sleep. So far, I find the OZLO Sleepbuds® 2 to be helpful in masking the outside noise and help me sleep a little better. I do hope one day to find a pair of sleep buds that are more comfortable for side sleepers. These do help me relax and fall asleep quickly, so for that, I do really like these sleep buds!

I am a person who has occasional difficulty both getting to sleep and staying asleep, so I was anxious to try this new technology to see if I could at least gain some insights if not improve my sleep. The first question I had to answer was if they were comfortable enough to wear while sleeping. I am a side sleeper, which means that I would be right on top of one of the sleepbuds. The 2 version has apparently been engineered to be smaller and fit flush in the ear so they are not uncomfortable while sleeping on my side and I did find that to be the case. The box comes with different sizes of silicone tips to get the right fit so they do not fall out or feel too tight. The battery life is just good enough to make it through the night, which I guess is all you need. The charging and data transfer case needs to remain close to your phone so that it can transfer "sleep session" information each morning when you put them back in to recharge. The sleep data is what I really like about this product. The sleep session details (Awake, REM, Core, Deep sleep) are beyond anything I have experienced with any other product.It also provides details on environmental noise levels, temperature, and light in the room. The last thing I will mention is that it has an alarm option, so I can hear the alarm in my ear without having to worry about waking up my wife. Yes, it is yet another case I have to carry and charge via USB-C, but I am willing to take it on my overseas trip based on what I have experienced so far.

If you have a hard time sleeping due to weird noises in your surroundings, or when traveling, or a mind that just won’t stop, the Ozlo Sleepbuds 2 might be worth considering for certain people. Think earbuds, but not quite what you think in terms of earbuds. These are not meant to be worn when walking around or about the house or at work. These are for sleep and rest only. The Sleepbuds 2 come in a larger, round, charging case. They of course include the pair of buds, as well as four sizes of silicone tips and wings that secure them to the inside of your ear, with size 2 being pre-installed on them. You also get sizes 0, 1, and 3. A USB-C charging cable is included as is a QR code to link you to the Ozlo app where you can control various aspects of the Sleepbuds. There’s no charging light on the outside of the case weirdly, but when you slide it open, you’ll see various pairing lights and a center control button and light. You seem to only be able to see the charge status of the case and each bud via the app. These do not connect to your Apple or Android phone in the traditional way most Bluetooth buds connect, as these connect to your phone through the actual charging case and app, so you need to keep the case within about 10 feet of your phone in order to keep a stable connection. Again, since these are for sleeping, you won’t be carrying the case around with you. It’s an odd way of connection, though. The way the Sleepbuds work is that you have a base of 10 sleep sounds built into the app that you can access once you set up an account. They range from nature sounds like an ocean and stream and various wind noises, to soft sounds that are basically white or pink noises, etc. There are other sounds available in the app that include things like the sound of a fan, being in a car, and more, but you need to swap out those for what’s on the device itself if you want them, so you only have 10 at a time on your case device, but can flip and flop them as you want. At the time of this writing, they have give or take, about 50 sounds in the app, and promise to add more. So far at least, I don’t see any indication that a subscription is required to access these. Once set up, you put the Sleepbuds in your ear and secure them after they’ve paired to your app and phone. They are comfortable. Very soft. The buds themselves as well as the ear wing to secure them in place. Now, Ozlo says they are also mean for side sleepers – as one, I can say they do not hurt on my side, but you DO know they’re there. I’m using the correct size bud tip, and it takes a few times to get used to them when sleeping, but again, they are not uncomfortable, but also not invisible to your brain – you do know you’re wearing them. The app along with letting you choose various sounds, allows you to set up modes that vary from allowing you to fall asleep listening to your own podcasts or music, where it will then switch over to a nature sound, or you can set it up to just listen to the built-in sounds right off the bad, or use a timer. You have varied options. There are NO mics on these, so if you get a call while wearing them, you cannot conduct your phone call through them; they are for listening only. There is also no true “noise cancelation” feature on these; instead, the sounds themselves are supposed to suppress and dissipate distracting outside noises on their own, with mixed results. I have noticed that using the timer (you can set up to 2 hours) will display the timer at the top of the app when set, but so far, it keeps playing even after the app timer runs out (?), and a few times the app has hung up when trying to use a mode and back up to use another, and I have had to close the app and reopen it again to unfreeze it. You can keep track of your sleep habits with the app as well. It does collect data, but you can turn this feature off in settings if you like. There does not seem to be a way at least that I can find in the app, of adjusting the individual volume of each bud, though. So if you want one to have a lower or higher volume than the other, so far I see no way of doing this. As far as the sounds go, most to me, are relaxing. A couple of them such as a stream, sound like a very short loop that just keeps repeating itself with an odd noise in the background that my brain fixates on. The ocean waves are so-so, but there are alternatives in the app you can replace them with. The rain and white noise sounds work best for me. Now, will these completely block out things like a loud snoring significant other, or a dog barking or kids screaming in your house? Definitely NOT. I tried playing various videos near me and in other rooms of snoring and dogs, and they again, did not fully block these. They will help diffuse the noises that are loud and indoors with you, or perhaps on a plane. I could also see these being useful for someone who’s in a hospital or physical rehab facility so they can get rest, which is impossible normally in those environments. I notice they’ve been good when my neighbor decides to leaf blow his yard at 7am, or when the neighbors across the street just has a loud party that went on until 3am. The Sleepbuds worked great in keeping those disturbing outdoor sounds out. They work well for what they are so long as you don’t expect miracles. Battery life is very good. You get about 14 hours on a fully charged set of buds (depending on volume), and can recharge them 2-3 times with the case. So, overall, I like the IDEA of the Sleepbuds 2. They do to a degree, mask out unwanted noises. They are very comfortable. Most of the sounds are relaxing and you have a decent amount to choose from, and battery life is very good. What do I not like? The case not having a charging light on the outside is odd. Needing the open case and app on to use the Sleepbuds as opposed to the more traditional Bluetooth way is also a bit quirky. The app while versatile, is so far for me a little buggy, has frozen a couple of times, and lacks a couple of basics like adjusting individual sound volume on each bud, or having any time of way to control base or treble on the sounds. And there’s the price… these are quite pricey for what they are. If you need them, you need them, and the price will be worth it to you. If you are a more casual-need type of person for this type of things, you can maybe get by with more traditional buds and a nature sound app working together. I give the Sleepbuds 2 three stars. I don’t think they’re bad at all. I just think they’re a little more of a specific niche item that could use a little work on the device and app (and price) to make them more attractive to the masses. I recommend these for people with niche uses for them, but also feel like for the majority, you may be able to get by with traditional comfortable earbuds and a nature app, for less.

I have had two prior versions of the major competitor to the Ozlo Sleepbudsfor. Each of them were very good but had their pros and cons. The comfort level of the Ozlo product is significantly better; they truly do not protrude from the ears. The sound quality is very good. Battery life is excellent. I don’t find the flexibility of the app regarding sleep masking to be quite as good as my prior earbuds, but that is a trade-off that I am more than willing to accept in order to have a comfortable night sleep. Ozlo is certainly more expensive, which is why I had delayed in purchasing these earbuds. I am, however, happy with the decision to move forward.  In a perfect world, these earbuds would have a microphone so that they could be used throughout the day for phone calls, etc. However, I understand that this would increase the size and weight of the earbuds and thus decrease the comfort level during sleep. 

I had been using my AirPods for sleep due to snoring but they never lasted the whole night and were so uncomfortable for nightly wear. After a google search I found these and they’re worth every penny. Completely block out the snoring and I sleep so much better.

10/10 wish these had came out sooner. Case is incredible blocks out noise for an excellent nights rest.

I love the fact that they stay in your ear even after you fall asleep. I was a little hard to understand the operating instructions, however once I did, they worked perfectly.

I really like these, super comfortable and really work well. I use them to mask my tinnitus and works perfectly.

Very comfortable earbuds barely feel them while sleeping but volume is too low for the price not worth it full price

I'm not a particularly light sleeper, but I've grown more sensitive to noise when trying to fall asleep. Anything that sticks out or follows an irregular pattern -- ceiling fans, neighbors, outdoor critters -- tends to distract me and make falling asleep that much harder. I started sleeping with a white noise machine years ago and find it invaluable. But that can't block everything out, and isn't the most travel-friendly option. Enter the Ozlo Sleepbuds 2. I remember reading about the original Sleepbuds when they came out, with their sleek look and Bose designer heritage, both of which came at a price and seemed a bit superfluous to me. Why not just wear earplugs if you really need to block noise? This category of purpose-designed sleep buds has definitely evolved quite a bit, and as someone who travels somewhat frequently, I thought it was about time to give it a try. Ozlo packages the Sleepbuds 2 in premium packaging in line with the price. The box is small and sturdy, nicely-layered and nearly all recyclable. I'm a sucker for a premium unboxing experience that's also sustainable, and Ozlo did a good job here. The Sleepbuds 2 system consists of a rather sizable aluminum case with a nifty sliding cover and embedded sensors. The case charges the buds and serves as the bridge with your phone, which is different than most earbuds, but enables much of the "smarts" to live outside the buds themselves, keeping them small and light. The case interface consists of a small round button with round LED light and two half-moon LED lights on the edge, one near each bud. The buds themselves are impressively small and lightweight; most of the material is actually the removable eartip/wing combo, of which four sizes are included in the box. The buds are a nice light beige color, while everything else -- case, packaging, charging cable -- are a soothing blue. The overall look and feel is definitely premium. The Ozlo app is similarly sleek yet soothing. It walks you through the initial pairing process, earbud fitting and general usage. The buds pair fairly easily and are responsive to the app, despite the fact that all commands run through the case before being transmitted to the buds. The only thing that took a bit of time was updating the firmware and loading Ozlo's masking sounds unto the Sleepbuds 2, both of which took a few minutes. Uploading sleep data also takes a fair bit of time, definitely more than a minute or two. I'm guessing this is all due to the limited bandwidth of Bluetooth, which the Sleepuds 2 case relies on to communicate with your phone. Tailoring the buds to your preference involves selecting from the many masking sounds in the app, setting an alarm and deciding how you'd like your buds to handle switching from streamed audio (podcast, book, music) to masking sounds. You can specify a time limit for streaming audio or let the buds detect when you fall asleep and switch automatically. I chose auto sensing, although I don't generally listen to audio when falling asleep. I think this is a great feature for those that do so you're not woken up when your podcast or playlist ends in the middle of the night. All settings are handled through the app and stick between sleep sessions. The only physical control is the case button, which allows you to play and pause audio, snooze the alarm and reboot the buds. It's designed to give you basic control in the dark without reaching for your phone, which is great. My only wish would be for some sort of volume control as well. There's no way to raise or lower your masking audio without reaching for your phone. The buds themselves are impressively small and light. I appreciate the multiple wingtip sizes, as I was able to go down a size for more comfort. I've had no trouble with the buds falling out of my ears, although sometimes one or the other comes a bit loose after tossing and turning. I know I can go back up a size if this bothers me, which I appreciate. As a side sleeper my chief concern was whether the Sleepbuds 2 would be uncomfortable, and I'm happy to say they're not. I can feel the buds in my ear, and if I put too much pressure on the ear facing the pillow I feel a bit of discomfort, but in general I've been able to sleep on my side without discomfort. This is pretty impressive. What I realized as soon as I put the Sleepbuds 2 in the first night, and what has continued to bother me, is that the Sleepbuds 2 give me the same annoying sensation as earplugs: there's something in my ear, I can hear my own heartbeat, breathing and blood pumping, and I don't like it. I was hoping the buds would somehow avoid this sensation, but as they rely entirely on passive noise blocking, they require a tight seal in your ear. With this comes the earplug feeling I don't like. This is part of the reason I went to a smaller wingtip size, as the seal is a bit looser and the sensation a bit reduced. Regardless, it's still there, and particularly prevalent when laying on my back. I found switching to my side eliminates a lot of the blood pumping/internal humming that drives me nuts. Thankfully I'm naturally a side sleeper, or this would be a dealbreaker entirely. After repeated use I'm a bit more comfortable with the sensation and can fall asleep, but more than one night I've woken up, taken the Sleepbuds 2 out and felt noticeable relief. Of course, no buds means no noise blocking, so I have to fall back on my white noise machine and turn off my noisy ceiling fan. It's a toss-up of which bothers me less, although I find myself not using the SLeepbuds 2 more than I use them. At the end of the day, this sensation is something that really bothers me, and is inherent to anything that seals tightly within your ear. I've gotten used to the sensation with earbuds (mostly due to playing music or other audio at mid/high volume), but with the Sleepbuds 2 I listen to a steady masking noise at low volume, making the sensation harder to ignore. That said, I can't fault Ozlo here too much: the device is doing what it's designed to do, which is seal tightly to block noise. I do see room for improvement here, though. First, with respect to the wingtips: it would be great to see some alternative designs that don't seal perfectly tight, but allow a bit of air movement. This would reduce the earplug feel and, yes, the sound isolation, but I'd be willing to sacrifice some isolation for more comfort. With the ability to turn the masking sound volume up I think I could find a better compromise than what's possible now. I'd also like to see a few usability/quality of life improvements to the case itself. First off, there's no wireless charging, and the case battery drains every few days. With Qi now a ubiquitous standard it feels a bit cheap to not include this, especially on a premium-priced product. Second, a physical volume control would be nice, whether through the existing center button or a separate volume rocker. I shouldn't have to open the app in the middle of the night if I need to adjust the masking sound levels. Third, despite the premium build, the Sleepbuds 2 case is not really travel-friendly. The lid slides open with the gentlest of touches, which starts the Bluetooth connection process and exposes the buds. Ozlo is well aware of this, as they sell a separate zippered travel case; at this price, I'd like the case included, or some sort of lid lock to activate when packing the buds for travel. Putting aside my personal annoyance with the sensation of earplugs, the Ozlo Sleepbuds 2 look and feel premium and generally perform very well. They are sleek enough to sleep on your side, they block noise well, they have all-night battery life and a wide variety of options in the well-designed app. That said, I think the case is too minimalist, and Ozlo should at minimum add wireless charging. I'd like to see a lid latch and volume control as well, or the travel case included in the purchase price. Finally, I'd happily try out different wingtips that give up some sound isolation for improved comfort/airflow. Despite all this, I'll keep using the Sleepbuds 2 when I need to really block noise. I think in particular they'll be a great addition (with the travel case) for hotel use, where loud HVAC units, hallway noises and snoring family members are the norm.

How much is a good night of sleep worth? If you’re considering the purchase of sleep buds, that’s the question you must answer. I generally have no trouble falling asleep, and I prefer to do so in silence, but sometimes my spouse will start snoring, and even minor snoring can be irritating when you’re desperate to fall asleep. I’ve been in situations where I’m sleeping away from home in a group setting (camping) and the different noises and sleep sounds prevent me from getting any sleep. In those situations, I’ve resorted to putting my regular ear buds in and downloading some “white noise” such as rainfall to help drown it out. Yes, that works, but regular buds aren’t designed for sleeping, and they inevitably fall out, meaning that the noises may wake you back up, and you have a scavenger hunt in the morning to find the lost buds. Enter the Ozlo Sleep Buds 2. I was intrigued by this product when the first iteration came out, but I never got around to getting them for myself. They’re pretty pricey, especially for something designed for such a specific purpose, but that’s why I asked the question above. If the Ozlo Sleep Buds could give you your sleep back, would that be worth it to you? I took the plunge and got the latest version, and I must say, I’m impressed! As a side sleeper, I couldn’t imagine being able to lay on my side while wearing earbuds. I’ve tried so many different styles of earbuds for normal usage, and I mostly don’t enjoy having them in my ear canals for very long. Fatigue sets in within about 2 hours, so I was skeptical about the Ozlo Sleep Buds. They come in a very nice aluminum charging case with a sliding top. Inside the case, you’re greeted with 2 LED light strips indicating the charging status. The only documentation you’ll find in the box is a tri-fold page telling you to download the app. There is a thick little booklet included that’ll give you safety information in lots of different languages—you know, the stuff that none of us read. I usually prefer at least some printed documentation to get me started, but I understand that it would take quite a booklet to convey any meaningful information, so they rely on the app. The app is well-done, and it walks you through the connection and setup process--it’s pretty smooth. There are 5 different sleep modes, and there’s also a Sleep Shield that will silence phone sounds and alerts while streaming from your phone. The simple, low-distraction mode allows you to simply put the buds in your ears and your sleep sound starts playing without requiring you to use the app. This is nice for when you just want to get to sleep, and it’s what I use. There are more than 30 options for a choice of sleep sounds, including things like rainfall, ocean waves, mountain winds, and more. There are also a number of steady white noise sounds that don’t fluctuate, which is great because there’s no distraction when you’re trying to remain laser-focused on sleep. While my focus is on masking noise and getting to sleep, these are fully functional Bluetooth earbuds, and that means you can use them to listen to music, podcasts or audiobooks while drifting off to sleep. I was pleasantly surprised at how good they sounded for music, so if that’s how you want to fall asleep, you won’t be disappointed in the sound quality. The buds and the case feature rudimentary sleep tracking functions, so you can set it to switch from streaming music to your chosen sleep sound when it senses you’re asleep. You can also set it to disable all Bluetooth connections after a time. Speaking of the case, I thought it did a good job of tracking my sleep. It actually matched the sleep tracking of my smart watch, which has access to other characteristics such as my heart rate. It’s not a dedicated sleep tracker, but it does a very good job of providing insights into your sleep, including what may have awakened you in the middle of the night. One of the most important qualities of earbuds is comfort, and this is even more critical for something you intend to wear all night. As I’ve tried out many different regular earbuds, I found the most comfortable ones to be those that featured an oval shape for the ear gels that actually go into the ear canal. The Ozlo Sleep Buds use a slightly oval shape, and I found it very comfortable. They come with several different sized wing tip silicone covers, ranging from size 0 (the smallest) to size 3. Size 2 is installed out of the box, but you’ll want to experiment to get the best fit. The combination of soft silicone and the wing shape work to keep them in your ears. I have yet to have them fall out—the fit is very secure. Here’s the best part—they stayed comfortable even when lying on my side! They’re so thin that the pillow does not push them deeper into the ear. I think that is amazing, and it’s one of the things that truly sets the Ozlo buds apart. I haven’t tried the competition, but in looking at photos of the others, none seem as small and light as these. Battery life is great, and I’ve had no trouble getting through 8 hours. They’re rated for 14 hours, but I’ve never stayed in bed that long, so I doubt I’ll ever reach that limit. The case is rated for an additional 2 charges. In practice, I haven’t had to charge the case more than about once a week. The Ozlo Sleep Buds do not include active noise cancellation (ANC), and this is purposeful. I found information where the company said that ANC is not as effective with sudden, erratic noises (such as snoring), and the extra circuitry only adds bulk without much benefit. With sleep sounds on, I found the Sleep Buds to be very effective at blocking out sounds with the combination of white noise and passive physical sound deadening (you’ve got something in your ears). That brings up the question of how you’ll hear your alarms in the morning. The Ozlo app includes its own alarm, allowing you to choose the type of alarm sound you want and how loud it should be. This works very well. If you choose to disable all Bluetooth connections, you’ll have to rely on the internal alarm. This is where I did find an annoyance. When the alarm went off, it was not brought to the foreground on my phone, requiring me to unlock the phone, bring up the app, and then silence the alarm. That’s pretty frustrating when your goal is to hit snooze and grab a few more winks. Fortunately, I found the alternate way to handle alarms—simply slide the case open and press the button inside. This snoozes the alarm and lets you get right back to sleep. If you don’t want to disable your connections so that you can continue to use your phone, you can do that too. When I did that, I found that the alarm sound played not only through the earbuds, but through the phone’s speaker as well. If you want to wake up without disturbing your partner, you’ll have to opt for the Ozlo app’s built-in alarm. The Ozlo Sleep Buds 2 simply deliver. Although I normally prefer falling asleep in silence, I found myself looking forward to the comforting environment created by the sleep sounds (just don’t set them to be too loud). Even when I was awakened by my spouse’s snoring in the middle of the night, it was easy to reach over, grab the buds and put them in. The sleep sound started up automatically, and I could go right to sleep. The Sleep Buds sound quite good for music and audiobooks, but with no controls on the buds themselves, they’re really not suitable to be your one and only pair of earbuds. Which brings us back to my original question: how much is a night of sleep worth? If you’re regularly getting your sleep interrupted, I think you know the answer. These did everything they claimed, and then some. I highly recommend them!

To begin, I should probably mention that I am one of those people who need white noise to sleep. When I am at home, I sleep with a fan on. When I am traveling, I bought myself a white noise generator to plug in (because small, portable fans were not loud enough and larger fans were too problematic to travel with). I do a lot of traveling and that worked well, until I shared a hotel room with my brother one night. His snoring was so bad, even the white noise generator could not drown it out. I actually wound up putting in my ear buds, connecting them to my phone, and trying to sleep like that. The problem, though, was that ear buds are not designed for sleeping. They fell out, I could not lie on my side, etc. When I saw these, it was a revelation and I hoped they would work as advertised. The short story is that they do. To begin, the buds themselves are rather small, somewhat cube-shaped speakers boxes that fit inside the silicone piece that fits in the ear canal and runs up into the inner ridge of your ear, holding the ear buds in place while sleeping while also providing a relatively flat surface that does not protrude from the ear, allowing me to sleep on my side without any problems. The case is about the size of a hockey puck, so it is easily transportable and it recharges via USB-C. The top slides open and there is a button inside that you push to activate the ear buds, snooze your alarm, etc. Personally, though, I found it easier to control the ear buds through the smartphone app. The app is very easy to use and intuitive. There are numerous options for having the sound turn off after a while or stay on all night. It also has a built-in alarm that works very well. The volume is easy to adjust (and the app gives you a warning if you set it too loud, although it does not stop you from doing so if you really want). You can download additional sounds onto the app, but it seems there are limited "slots" in the app for the sounds, so if you want to add one, you have to remove one. There are numerous sound options, though, so I would suspect everyone would find their favorite (or a few favorites) and not need the full library anyway. There is also a feature where the ear buds sync biometric data with the app to track your sleep. (Kind of like a watch or ring, but through the ear buds.) The batteries seem to last a decent amount of time and having them on all night does not seem to be a problem at all. These might actually be good ear buds for working out, considering how snug they are in the ear (and the "wings" keep them in place). Speaking of which, there are different sizes for the silicone parts to accommodate different size ears. It is hard to imagine these not being able to fit most of the population. Needless to say, these ear buds are filling somewhat of a unique niche, but they do so very well. Considering their intended use, I am having trouble finding anything negative to say about them. Now that I think about it, these would probably be perfect on an airplane if you're looking to drown out the noise and sleep a bit. I will have to try that out next. Oh, one limitation is that, while there is an app you need to use and it appears as though the earbuds connect via bluetooth, the instructions state that the charging puck (for lack of a better term) needs to stay a reasonable distance within the ear buds and your phone. Not sure if that means the ear buds connect to the puck and the puck connects to the phone? Really doesn't matter when I'm sleeping because the nightstand is pretty close to me, the ear buds, and my phone. Just something that seemed a little odd, though.
