Who we are

The Yeolrim is a Korean technology-oriented company, established in January 2015, which conducts research and development and sells products such as Smart Personal Sound Amplification Products, Smart Hearing Aid, and Truly Wireless Stereo solutions.

Leveraging the Internet of Medical Thing (IOMT) innovation, a key area of the fourth industrial revolution in the 21st century, THE Yeolrim has unique research and development technologies, commercialization capabilities, sales products and hearing loss solutions. THE Yeolrim has registered 5 patents related to hearing loss care and wireless earphones in Korea, and 1 patent in the U.S. Also, we have applied for 5 patents related to AI voice amplifiers and AI hearing aids with the Korean government.

According to a 2018 report released by the World Health Organization (WHO), the world's hearing impaired population is 470 million and is expected to increase rapidly to 900 million by 2050. Technological solutions abound but are too expensive for most. THE Yeolrim hopes its innovative, patented technology can provide a solution and social impact value to deaf people around the world.

THE Yeolrim can measure and fit its hearing directly in real time depending on the external environment and noise conditions through the self-controlled smart healthcare device. In addition, we are developing new products that can collect health data such as heart rate, exercise, dementia, and fall injury through addition of a health care convergence function.

User convenience and satisfaction are top priorities for the innovation pursued by THE Yeolrim. THE Yeolrim's product is an ear-bud type that can be worn like a wireless earphone and simultaneously features BT earphones, hands-free and hearing aids.

THE Yeolrim's products can be purchased for a remarkably low price compared to other hearing aids. They provide equal performance, and come with charging cradles to increase convenience and further reduce costs.

THE Yeolrim is a smart healthcare and AI medical device, venture company that applies innovative technologies developed in the fields of smart voice amplifiers, smart hearing aids, and wireless earphones.

"We aim to accumulate personal health big data by commercializing wearable smart and AI healthcare products, including voice amplifiers, hearing aids, and wireless earphones, and to provide customized health care services in conjunction with hospitals.

Korea's famous venture capital CEO who invested in THE Yeolrim sid: The global aging society, the expansion of the deaf population to all age groups, the consumer demand for various convergence functions, price-competitive products through price destruction, and the demand for design innovation products will explode. We're investing in pain-treating items and technologies that ease consumer inconvenience."
