Title: OceansBio USA to Launch BeCozU - an Earbud-Style taVNS Wellness Device to Help Improve Sleep

New York, NY, United States, 26th Aug 2025 - OceansBio USA (CEO Hyunung Lee) today announced BeCozU, a wellness solution designed to help modern adults improve sleep quality without medication or clinic visits. BeCozU combines transcutaneous auricular vagus nerve stimulation (taVNS) with an earbud-style form factor and real-time biosignal monitoring so users can support healthier nighttime routines at home.What is taVNS?taVNS delivers gentle electrical pulses to areas of the ear innervated by the vagus nerve. This non-invasive approach is associated with activation of the parasympathetic (“rest-and-digest”) response and may help users settle before bedtime. BeCozU operates in a low current range of 0.5–2.0 mA.Company study resultsIn a company-run pilot study conducted in 2024, participants who used taVNS showed a 71% improvement in Insomnia Severity Index and a 62% improvement in Epworth Sleepiness Scale compared with non-users. OceansBio plans additional clinical evaluations this year to further assess the effects of taVNS across a broader user base.“Many people struggle to fall asleep because of stress, relentless schedules, and constant screen exposure,” said Hyunung Lee, CEO of OceansBio USA. “With BeCozU, our goal is to provide a simple, comfortable way to encourage relaxation before bed—typically 15–30 minutes—while giving users clear, real-time feedback about how their bodies are responding.”Key features of BeCozUEarbud-style, truly wireless design for everyday convenienceReal-time PPG (plethysmography) biofeedback to show physiological responses (e.g., heart-rate trends) during stimulationCompanion app to start/stop stimulation, schedule sessions, and view daily/weekly trendsAI-driven insights that analyze stimulation history a...
