The Evolution of Sleep Innovation
Born from years of sleep research and testing, the Znie S-300 is the next generation of award-winning sleep device.
Fall asleep naturally, wake up renewed.
With the steady hush of pink noise and the gentle support of ELF waves, sleep comes the way it should, naturally.
Why Znie S-300?
Because better sleep isn’t just about tonight — it’s about how you feel tomorrow.
Pink Noise
Drift off naturally as calming pink noise helps quiet your mind.
Adaptive 8H Sleep Cycle
ELF frequencies automatically guide your brain through each sleep stage, keeping rest deep and balanced all night.
Wake Up Mode
Wake gently with soft light and morning care frequencies, so you start the day refreshed and energized.
