The app is useless

So the buds work as they are supposed to but the app sucks. 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!

Love this

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!

New update with bugs

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.

Updated UI is impossible

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!

App not connecting to other apps in new update

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.
