About this app

Ozlo Sleepbuds® are tiny, ultra-comfy headphones designed to give you the best sleep of your life. They come with all-night battery life, noise blocking, audio streaming, and biometric sensing.

The Ozlo app allows you to personalize your Sleepbuds experience, with controls for all your important settings and reports for your sleep data.

LUXURIOUS COMFORT
Sleepbuds® are surrounded with super soft, squishy silicone tips for unparalleled all-night comfort, even for side sleepers. And they're specifically designed to be low profile, so they don't stick out causing undue pressure on your ear like other earbuds. 

LONG BATTERY LIFE
Sleepbuds® can play for up to 10 hours for all-night noise masking or streaming. The Smart Case can provide additional charges so you can take it with you anywhere you go.

NOISE BLOCKING SLEEP SOUNDS
Each of our Sleep Sounds has been engineered to cover up sleep-disrupting noises like a snoring partner, city sounds, or your party-loving neighbors. All so you can fall asleep — and stay asleep — all night long. Find your favorite and get some rest.

STREAM ANYTHING
Sleepbuds® allows you to stream whatever content puts your mind in its happy place to help you fall asleep (Spotify, YouTube, Netflix, Audible… anything).

PERSONAL IN-EAR ALARM
Sleepbuds® have an in-ear personal alarm that gently wakes you from your slumber without jarring you or your partner. 

SLEEP SENSING
The biometric sensors built into Sleepbuds® allow us to detect when you fall asleep. With this important info, we can automatically switch from the audio you were streaming to your sleep sound, and keep you disruption-free.

PHONE-FREE
Simply remove your Sleepbuds® from the case and your chosen sleep sound will start playing automatically. In Bluetooth Disabled mode, we shut off the Bluetooth radios and play audio directly from the memory on your Sleepbuds®.

SLEEP TIMER
Automatically shut off your Sleepbuds® audio after a set period of time.

SLEEP TRACKING (coming soon)
Track your important sleep stats over time and gain insights into your sleep health.

ENVIRONMENTAL TRACKING (coming soon)
While your Smart Case charges on your nightstand, sensors detect the noise, light, and temperature of your room. We use this information to provide you with a personalized report every day in the Ozlo App.

not sure what has happened but when my buds updated it has completely screwed up my case and earbuds from connecting and disconnecting correctly I can no longer listen to music at all. if one is taken out then it will work for 4 seconds until I try to take the other one out, then I can't even get it to dobany audio. Ive turned re-downloding the app + unpairing and pairing for seriously too many times count on my vacation. should have juat brought my beats. so unsettling as I USE TO LOVE THESE

I've never been more frustrated by a Bluetooth device, a shame considering these are supposed to be a relaxing product. Bizarre pairing methods requiring the phone to connect to the case rather than the buds isn't worth the tradeoff of not needing a phone to play sleep-sounds. The best I can say is the sleep sounds are relaxing & the earbuds are comfortable. Update: latest firmware causes one earbuds to play higher pitched for first minute of use, and phone alarms no longer play in buds.

-Update! getting there but connection issues still suck. They mostly work but this last update is causing issues. Going to have to factory reset I guess. -------- My sleep buds were delivered June 1st and haven't ever worked right. The disconnect issues have not been resolved and this has become one of the most frustrating indiegogo purchases I've ever backed.
