Digital Sleep Earplug
Sleeby by Sleepy Inc. is an innovative digital earplug designed to induce sleep through non-pharmacological neuro-modulation. It applies brainwave entrainment technology to deliver binaural beats proven through clinical trials to suppress central nervous system activity safely and effectively.

Unlike app-based products that require smartphone connectivity, Sleeby functions as a stand-alone device—simply remove it from its charging cradle and insert it into the ears to activate. This unique “digital sedative in your ears” concept enables easy and immediate use anytime, anywhere. Weighing just about 3 grams per unit, Sleeby’s ergonomic design ensures comfort even when lying on one’s side during sleep.
By generating precise frequencies independently from each ear unit, Sleeby achieves highly synchronized binaural beats without relying on mobile playback, delivering consistent and refined audio stimulation. It offers a drug-free sleep aid alternative for those who cannot take sedatives, such as pregnant women, nursing mothers, and patients with medication allergies.

The small cradle size (approximately 6.7 × 2.4 × 3.5 cm) ensures excellent portability, allowing users to benefit from quick relaxation during travel or medical procedures requiring mild sedation or anxiety relief.
Targeting an estimated retail price of 150,000–200,000 KRW, Sleeby provides greater affordability compared to conventional sleep-inducing devices priced between KRW 300,000 and 400,000. With its smart, compact, and independent design, the device expands usability beyond daily sleep improvement to include clinical applications, representing a new paradigm in digital sedative technology.
Founded in April 2024, Sleepy Inc. is a Seoul-based digital healthcare startup specializing in non-drug solutions that influence the central nervous system (CNS). The company is developing advanced technologies aimed at realizing the concepts of digital sedatives and digital anesthetics.
Led by a Seoul National University Hospital professor of anesthesiology and pain medicine, Sleepy Inc. combines clinical expertise with cutting-edge R&D in neuroscience and digital health. Its upcoming Kickstarter campaign marks the company’s first step toward entering the global wellness and medical device markets.
