I can’t download any new sleep or alarm sounds (merely hit the preview play button) and it takes an engineering degree in rocket science to even figure out to select your sleep sound. Both times I have “stumbled” upon it and can’t remember which direction to the magic mystery doorway that I stumbled through. I’ve not tried customer support. It’s set to sensor, I begin listening to my podcast and fall fast asleep and it takes over with the sleep sound perfectly and plays all night…it’s just not a sound I want to listen to night after night. I like variety! And this morning I woke before the alarm but can I find where to turn that off? Vekk no. This app needs a LOT of work. It is useless! ### 5/5 — Love this *2026-08-18, version 2.63.3* I use the ozlo sleepbuds 2 - been using them for a week now Tried the soundcore a20, zykhon cheap buds, liberty soundcore - even my AirPods Pro My problem is terrible tinnitus The main issues with other brands is a) shaky connectivity b) they ALWAYS fall out c) the other tends to clog with earwax and are impossible to clean out The Ozlos are the first I’ve tried that stayed in, are comfortable for a side sleeper, and last all night and have rock solid connectors Haven’t had to clean them yet but I’ve read it’s better than the others So far they’ve been worth the premium - thanks Ozlo! ### 1/5 — New update with bugs *2026-08-15, version 2.62.2* Unable to use the simple streaming feature, where Bluetooth stops after 10 minutes, since the new update. So frustrating because I don’t want this additional WiFi exposure while I’m sleeping. Customer support has been little help. ### 2/5 — Updated UI is impossible *2026-08-14, version 2.62.2* Since the UI was updated the modes are impossible to understand, and for me at least it has resulted in the loss of useful functionality since I can no longer get the sleep bugs to switch from playing audio book to playing a making sound when it detects I’ve fallen asleep. I think that mode is supposed to be there, but it’s no longer working like it used to. If you need three layers of help text to try to explain how settings work that should be a clue that they are too complex! ### 1/5 — App not connecting to other apps in new update *2026-08-13, version 2.62.1* The new update seems to have a bug. Recently sleepbuds are connected, but only momentarily work for playing audio on another app. No issues with the soundscapes, but I have been unable to listens to any audiobooks or podcasts which are preferable to me to actually fall asleep and the reason I purchased them. ### 5/5 — My Sleep Buds *2026-08-09, version 2.62.1* Love these ### 5/5 — Excellent *2026-08-06, version 2.62.1* Difficult sleeper with a disquiet Mind. Ozlo’s are very comfortable and help keep me asleep. ### 4/5 — Where’s the snooze?? *2026-08-05, version 2.62.1* Loved the app until the update removed the snooze feature. ### 5/5 — Thank you Ozlo! *2026-08-04, version 2.62.1* I have used the Ozlo sleep buds for a few years. I purchased them originally when I lived in the city and go not hear spouse who snores. I purchased the Ozlo 2 just the other day and have used them 2 nights now. The Ozlo 2 is worth the money - better sound and longer battery are amazing! Thanks Ozlo ### 5/5 — Well worth the price *2026-08-04* 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! ## Frequently asked questions about Ozlo Sleepbuds ### What do Ozlo Sleepbuds do? Ozlo Sleepbuds are tiny, ultra-comfy headphones designed to enhance your sleep.
