Review: Best sleepbuds on the market - I bought these as a replacement for my Bose Sleepbuds, which lasted around two years before developing technical issues. Overall, they feel very similar, with a few improvements. Yes, they are expensive, but they are the only sleep earbuds that really work for me. They are incredibly comfortable, unlike many comparable products where the earpieces feel too bulky and uncomfortable, especially for side sleeping. I can wear these all night without any issues. The sounds do a great job of masking snoring, which is the main reason I use them, and they perform very well in that regard. The app is straightforward and easy to use, and connectivity has been solid. One improvement I really like is the ability to stream audio from other sources, which was not possible with the Bose Sleepbuds. I also like that once your streaming finishes, the earbuds automatically revert back to your chosen sleep sound. As an Android user, the sleep biometrics feature is not currently working and just says “coming soon,” but that is not something I bought them for anyway. I do hope many of the tech issues that affected the Bose version have been sorted with these. Overall, if you are looking for comfortable sleep earbuds that effectively mask noise, these are excellent. Review: Don't Waste Your Money - These Don't Block Anything - I really wanted to love the Ozlo Sleepbuds. The idea of tiny headphones playing sleep sounds seemed perfect. Unfortunately, they failed to deliver on the most important promise: blocking out noise. Despite trying every ear tip size included, I could easily hear conversations happening across the room - zero noise cancellation. Forget hoping to drown out a snoring partner or street noise. While the sound quality of the sleep sounds themselves was okay, and I didn’t have any Bluetooth connection issues, those positives are completely overshadowed by the fact that they just don't work as noise-blocking headphones. And to add insult to injury, it consistently took a frustrating 8 minutes to transfer a new sleep sound to the buds. That's a long time when you're trying to wind down for the night! Finally, they were just uncomfortable to sleep with. Save your money and look for a different solution. These are a disappointment. ## Features - Clinically Proven Sleep Technology: Ozlo Sleepbuds are clinically proven to help you fall asleep faster and stay asleep longer without medication or side effects. Designed with decades of headphone engineering expertise, these sleep earbuds combine passive noise blocking with science-backed sleep sounds to quiet your environment and calm your mind. - Ultra-Comfortable for Side Sleepers: Engineered with ultra-soft silicone tips and an ultra-tiny profile, Ozlo Sleepbuds sit flush in your ears for pressure-free comfort in any sleeping position. Side sleeper approved for all-night wear without soreness or slipping. - Block Out Snoring and Disruptive Noise: Soft ear tips passively block noise while built-in sleep sounds mask common disruptions like snoring partners, barking dogs, city traffic, and noisy neighbors. Designed to help you reclaim quiet, restful nights. - 10-Hour Bluetooth Streaming All Night: Stream your favorite music, audiobooks, podcasts, or white noise for up to 10 hours on a single charge using Bluetooth Low Energy. The Smart Case holds an additional 32 hours of charge and provides extra power on the go, making these wireless sleep earbuds perfect for home and travel. - Smart Sleep Detection and In-Ear Alarm: Built-in biometric sensors detect when you fall asleep and automatically transition from your streaming audio to soothing noise-masking sounds. Wake gently with the personal in-ear alarm that rouses you without disturbing your partner. - How Ozlo Sleepbuds Connect: The Smart Case bridges your phone and earbuds - it connects to your phone via standard Bluetooth and streams to the Sleepbuds using Bluetooth Low Energy. This means a smaller battery, ultra-tiny size, and all-night comfort. Keep the case within 10 feet and your phone within 30 feet for best performance. - Designed for Sleep, Not Calls: Ozlo Sleepbuds do not have microphones in the earbuds and cannot take phone calls - by removing the mic from the buds, we made them smaller and more comfortable for all-night wear. The Smart Case does include a built-in microphone, but it is designed solely for environmental noise monitoring, not voice calls. Paired with sensors that track room light, temperature, and barometric pressure from your nightstand, it captures the environmental data that powers your sleep insights in the Ozlo Sleep App. - Travel-Ready Sleep Companion: Compact enough for carry-on bags and hotel nightstands, Ozlo Sleepbuds are an essential travel accessory for frequent flyers and road warriors. Block out airplane cabin noise, unfamiliar hotel sounds, and jet-lag disruptions to sleep well anywhere you go. - Built by Former Sleepbuds Engineers: Founded by three engineers with decades of headphone expertise, our team acquired the original Sleepbuds patents and redesigned every component from the ground up. The result is a next-generation sleep earbud engineered for reliability, comfort, and your best sleep yet. - Ozlo Sleep App and Sleep Patterns: Download the free Ozlo Sleep App (iOS and Android) to customize your sleep sounds, set in-ear alarms, and manage sleep detection. With Sleep Patterns (Beta, iOS), access a personalized daily sleep report powered by your environment - understand not just how long you slept, but how consistently and efficiently. Smart Case sensors track sound, light, temperature, and barometric pressure to reveal how your surroundings impact your rest. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0DJB1ZL8V | | Age Range Description | All | | Best Sellers Rank | 45 in Sleep Earbuds | | Box Contents | Protective Case | | Brand | Ozlo | | Brand Name | Ozlo | | Colour | White | | Compatible Devices | Smartphones, Tablets, Smart Speakers | | Compatible devices | Smartphones, Tablets, Smart Speakers | | Country of Origin | China | | Customer Reviews | 3.5 out of 5 stars 1,688 Reviews | | Enclosure Material | Silicone | | Form Factor | In-Ear | | Form factor | In-Ear | | Item Dimensions | 13.6 x 5.8 x 13.6 centimetres | | Item Weight | 100 Grams | | Manufacturer | Ozlo | | Manufacturer Part Number | 01001100WW1 | | Material | Silicone | | Model Number | HEADPHONES | | Number of Packs | 1 | | Product Features | Advanced Noise-Masking, All-Night Battery, Side-Sleeper Comfort, Soft Silicone Design | | Shell Type | Soft | | Shell type | Soft | | Theme | Sleep Technology | | UPC | 860010876145 | | Unit Count | 1.0 count | | Water Resistance Level | Not Water Resistant | ## Product Details - **Brand:** Ozlo - **Colour:** White - **Connectivity technology:** Wireless - **Ear placement:** In Ear - **Form factor:** In Ear - **Headphone jack:** No Jack - **Impedance:** 250 Ohms - **Model name:** ww-ozlo-sleepbud - **Noise control:** Passive Noise Cancellation - **Wireless communication technology:** Bluetooth ## Images ![Ozlo Sleepbuds - Sleep Earbuds for Side Sleepers, Noise Masking Technology, 10-Hour Sleep Streaming, Snore Blocking Sounds, Ultra-Comfortable In-Ear Design - Image 1](https://m.media-amazon.com/images/I/61W4r59jo3L.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: Can Ozlo Sleepbuds help block out my partner's snoring?** A: Yes.

My previous favourite were the Bose quiet comfort in ear headphones because of the soft silicon tip. How did I get on with the Ozlo headphones?Phenomenal. Our holiday was transformed from my usual grumpy mornings and need to have naps in the afternoon to actually feeling awake all day because I’d had a decent nights sleep. Game. Changed. Since getting home, its only got better. No more waking up to the loud bits in my audiobooks. Waking up feeling refreshed instead of dragging myself out of bed. Can’t speak highly enough of them. The Ozlo headphones are expensive, but well made, super comfortable (side sleeper), easy to setup and use and honestly worth every penny. Battery lasts all night without annoying low battery warnings waking you up. And you only need to charge once every two nights cos the case fully recharged the headphones themselves. The insights you get on a morning in the app are an added bonus - tbf I dont need them to tell me my sleep has improved because not only me but my family has noticed the difference. Have already recommended to family and friends and seriously considering getting a second pair in case they ever stop making them.
