The world's first sleep mask integrating BCI technology, EEG and AI algorithms, exclusively enabling real-time monitoring and intelligent regulation throughout all sleep stages—before, during, and wake-up. It improves falling asleep speed by 50% and deep sleep ratio by 30%. Its 4D sleep-tech stack combines BBT binaural beats, far-infrared heat therapy, EMS stimulation, and vibration massage, paired with a 100% light-blocking zero-pressure eye mask. Suitable for multiple scenarios including home sleep, travel, and environments with light interference, it works reliably both online and offline—redefining a new approach to scientific sleep.
