Hello,
This is Once, greeting you again with For me buds.
‘For me buds’ is a product launched by db beats, a company founded by engineers who developed mobile devices through LG Electronics' in-house venture program and a planner who led Open Innovation. It is an innovative platform device that enhances quality of life by managing mental health through scientific methods.
‘For me buds’ is a product that has been validated for EEG measurement and sleep induction algorithms with 150 general participants at five major hospital sleep centers, and its accuracy has been confirmed by comparing results with 7,700 polysomnography tests.
In particular, since October 2022, we have verified the effectiveness of sleep management and personalized algorithms through beta testing with 1,000 participants.
Now, mental care is expanding from sleep management with proven solutions to the entire circadian rhythm mental health management area, and with expanded sensors and advanced algorithms, various industry players can apply it.
