About this item CLINICALLY PROVEN: Our Sleep Technology is Clinically Proven to Help You Fall Asleep Faster and Stay Asleep Longer, Without Pharmaceutical Intervention – and the Associated Side Effects. STREAM ALL NIGHT: Enjoy up to 10 hours of playtime on a single charge, with the Smart Case providing extra power on the go for added convenience and portability. SLEEP DETECTION: Sleepbuds' biometric sensors can seamlessly detect when you fall asleep, auto-magically switching from your streaming audio to built-in noise-masking sounds. HOW THEY WORK: Ozlo Sleepbuds use an innovative connection system where the Smart Case acts as a bridge—connecting to your phone via standard Bluetooth and streaming audio to the Sleepbuds using Bluetooth Low Energy (BLE). This reduces power needs, allowing for a smaller battery and ultra-tiny size that’s comfortable all night, in any sleeping position. For best performance, keep your Sleepbuds within 10 feet of the Smart Case, and your phone within 30 feet. IN-EAR ALARM: Ozlo Sleepbuds have a built-in personal alarm that gently wakes you from your sound sleep without jarring you or your partner. SUPER COMFY: Side Sleeper Approved. Ozlo Sleepbuds feature ultra-soft, squishy silicone tips that mold to your ears, providing unparalleled comfort and a secure-fit, even for all-night wear. DESIGNED FOR SLEEP, NOT FOR CALLS: Ozlo Sleepbuds are made for one thing: helping you sleep better. They do not include a microphone and cannot take phone calls, because they are not regular earbuds. Instead, they are ultra-compact, incredibly comfortable for all sleep positions, and built to block out the noises that interrupt your rest. Every detail is designed to support better sleep, not daily use.
