more I have had severe insomnia tor two years. I’ve been to numerous sleep specialists, flown to other cities to meet with doctors who specialize in sleep, tried a CPAP machine, every drug known to medicine, created perfect sleep hygiene habits, tried CBT for Insomnia… you name it. None of those treatments worked for me. I was hospitalized because of my insomnia at one point. The gentle noise of rain, ocean, white noise (any of them) works, BUT it only works for me if I have earbuds because having the sound coming out of a speaker in the room does not give me the same results. Naturally I tried every earphone for sleep option I could find. Air Pods, sleep masks with Bluetooth speakers built in, smaller earphones, wired earphones, basically I tried everything. When I saw Oslo Sleepbuds I was a bit skeptical because I didn’t want to spend $300 for yet another gimmick that wasn’t going to work. I was desperate so I bought them. They are the ONLY thing that has worked for me. The sound quality is great, they fit my ears perfectly, I sleep on my side and never in my back and they are so small and comfortable that I have never once felt them in my ear or been woken up by discomfort. I almost never give reviews, but this is a product I believe in and I hope this review helps anyone suffering the way I was. I bought thousands of dollars worth of various earphones to help me sleep and they did not work. I am falling asleep fast, staying asleep all night, and waking up refreshed. My sleep monitoring devices are all scoring my sleep at above 90% with these sleephones. I am so glad I found these.

I love the buds for the size, comfort and battery life but the app is, as another reviewer said, garbage. Ozlo needs to get their act together to fix these issues and improve the functionality. I’m glad I did the subscription instead of buying these outright as I do not know if I will keep them. The sound library is a joke; the sound quality when streaming is awful and should embarrass former Bose employees; once you set an alarm you cannot change or delete it, so you just keep adding alarms; noise masking barely masks noise—options for noise masking or noise cancellation would be an improvement. The Bluetooth range is ridiculous—it’s less than 10’ before you lose connectivity. The user guide instructions say to move the charging case facing left toward your head and then place your phone to the right of the case for optimal connection—really? That is the best Ozlo can do for this price point? I’m disappointed because the reviews say Ozlo is the GOAT of sleepbuds. The physical product might be the best, the software/firmware whatever it is called needs major work.

The app is generally super easy to use and understand. There’s just a few things that are a little strange. 1. You can’t listen to or even see the names of the sleep sounds until the case is open. It can also take a few seconds for the app to respond once the case IS opened. Which has lead to me wondering if I did something wrong on a few occasions.2. The settings on when/how the earbuds begin playing your chosen sleep sounds can be confusing at first. The explanations of the options are a bit wordy, and it took me a few rereads to fully understand how what I selected was going to affect the playback. But none of those gripes are really a big deal. Overall my experience has been great! Here are some things I super like: 1. Browsing and selecting sleep sounds is easy, and I feel there is a wide enough selection that there is something in there for any kind of sleeper. 2. The volume for your sleep buds is controlled directly by the app (for both your sleep sound and your alarm). So you can have your ringer volume all the way up while keeping your sleep sounds at a comfortable volume (for me in the 40%-50% range).3. Changing how/when you want your sleep buds to play is very easy. It’s all one or two taps away. 4. Once connected, the app tells you exactly what percentage of battery the case and the sleep buds are at. It’s very convenient to slide the case open and check if I need to gos the them when I get home from work. I’m enjoying the app and the sleep buds a lot. Excited for future updates :)

Amazing product! Unsure of earlier generations, this is my first Ozlo product, but they nailed it. The tech for customizing sleep sounds, when they start, how they integrate to your phone, etc is extremely well done. I like doing meditations to help quiet my brain before sleep, but am always annoyed that you have to end a session, put away earbuds, etc before going back to sleep. Now I can set a meditation, when it ends, go straight into sleep noises, and not worry about taking anything out or turning anything off. It’s seamless. The ergonomics of the buds are also extremely well designed. I’m a side-sleeper and barely feel these in my ears. I use an Apple Watch and Oura Ring. Last night, apple had my sleep score at 99; Oura had my sleep score at 97 (highest I’ve ever had). Well worth the cost!

We're excited to introduce Sleep Patterns (Beta), our most powerful new feature yet. Sleep Patterns turns your Sleepbuds and Smart Case into a true sleep companion, showing you not just when you slept, but how, and why you feel the way you do in the morning.
• Track each nights sleep against personalized Sleep Goals (duration, consistency, efficiency)
• See how long and well you slept.
• Understand what's disrupting your rest — like noise, light or temperature shifts.
• Recognize how your Sleepbuds stepped in to mask sound disruptions and protect your rest
• Review your last 30 days of sleep to track progress and discover what works best for you.
• Please make sure to update your Sleepbuds to the latest firmware to unlock this feature.
We are also releasing 6 new Sleep Sounds:
• Autumn (Masking) — A crisp, windy day - leaves rustle and swirl, creating a natural blanket of noise that quiets the world around you.
• Steady Heat (Masking) — A soft electric heater hums steadily, its gentle buzz wrapping you in warmth and calm while masking nighttime disruptions.
• Rainy Nook (Soundscape) — Immerse yourself in the comforting sound of peaceful rain on a window pane with a warm fire nearby, transporting you to a cozy nook where you can unwind and drift away.
• Subtle Waves (Soundscape) — Gentle swells rise and fall along the shore, their soft rhythm washing away the day and easing you into calm, steady rest.
• Outboard (Soundscape) — The low purr of an outboard motor blends with the open air, a steady, soothing pulse that carries you across rippling water into quiet focus.
• By The Bay (Soundscape) — Distant gulls call and water laps against the docks, creating a peaceful marina backdrop that drifts between calm motion and coastal stillness.
