Sleepbuds®

Ozlo’s Sleepbuds® are designed to tackle the real culprit behind poor sleep—noise. By using clinically proven Sleep Technology, they help users fall asleep faster and stay asleep longer, without pharmaceutical intervention or their side effects. By helping to block disruptive noises like snoring or noisy surroundings, the Sleepbuds® ensure a truly restful night. Every detail, from comfort to sound quality, is carefully engineered for the best sleep experience possible.

Quality sleep is essential for health and performing at your best, yet it remains a struggle for many. To solve this, Ozlo has assembled leading mechanical, electrical, audio, and software engineers to create smarter, non-pharmaceutical solutions. By combining science and technology, they develop innovative products that use audio to enhance rest, helping people achieve better, more restorative sleep.
