[Immersive and Private Listening Experience]: Innovative directional sound wave technology combined with a multi-level acoustic cavity structure precisely controls audio frequency bands, creating a stereo sound field around the pillow. When listening to soothing music at night, it maintains a private sound field, undisturbed by the sleeper, creating a personalized immersive sleep environment. [Independent Listening Space]: Through physical sound insulation and conduction solutions, sound waves are concentrated in the sensitive area of the head. The volume can be freely adjusted, forming a private sound barrier. This allows partners to enjoy their own music while sleeping, effectively solving the problem of noise interference in shared spaces. [Stable Wireless Connection]: Equipped with a Bluetooth 5.4 chip, it establishes a low-latency transmission channel with the main unit… This smart device supports a stable connection within a 10-meter range, allowing you to smoothly play sleep-aiding music in the room without frequently moving your mobile devices. [Multiple Soothing Sound Effects]: Built-in natural rhythms such as ocean and rain sounds, combined with customized sleep-aiding frequencies, adjust the nerve relaxation threshold through sound wave resonance. Tailored for children's light sleep needs and adults' deep sleep needs, it shortens sleep onset time and prolongs deep sleep cycles. [Long-Lasting Music Companionship]: Optimized energy-saving algorithms ensure ultra-long battery life. With its intelligent timer shutdown system, it ensures stable output even when playing white noise all night. Whether you're out or at home, you don't need to worry about power outages.
