Multi-Dimensional Technology · Negative Oxygen Ions
58230 at 3 m — 3.6× the Liuxi River
Technical Specifications
The Z5 outlet measures 1.9×10⁸ pcs/cm³, released from carbon-fiber tips in small, highly active particles. After decay, the concentration at 3 m is 58,230 ions/cm³ — about 3.6× the Liuxi River and 58× the WHO standard.
What It Does for Sleep
The nightstand sits just 2-3 m from the device. At this distance, negative oxygen ions activate the parasympathetic nervous system, helping the body switch from “alert” to “rest”. Not hypnosis — a return to the sleep rhythm you were meant to have.

Multi-Dimensional Technology · Schumann Resonance
Saying “Time to Sleep” at the Earth’s Frequency
Technical Specifications
A natural electromagnetic resonance exists between the Earth and the ionosphere, with a base frequency of about 7.83 Hz. The Z5 has a built-in Schumann resonance module measured at 7.837 Hz, matching the Earth’s base frequency. Zhongren Yingtai report No. 20251218W42013X.
What It Does for Sleep
As you fall asleep, brainwaves shift from β (awake) to α (relaxed) to θ (light sleep). 7.837 Hz falls within the α-θ transition band, giving brainwaves a push “toward sleep”. Nothing to wear, nothing to touch — place it on the nightstand and it works the moment it is on.

Multi-Dimensional Technology · Sleep Healing Music
Not to Lull You to Sleep — to Stop Other Sounds from Waking You
The Z5 comes with multiple professionally recorded natural soundscapes, with adjustable volume and timers. Hearing is the last sense to switch off as you fall asleep — a single footstep upstairs can drag your drowsiness right back. Natural soundscapes lay down an acoustic masking floor, so sudden noises landing on it no longer stand out.
Sleep Tracking
Connect smart rings, bands, millimeter-wave radar or sleep mats and check your sleep report in the morning — the data tells you how you slept.
6,000+ Healing Tracks
Choose from healing music of every kind — natural soundscapes, sleep albums — there is always one for tonight.
Real-Time Remote Device Control
Connect to the sleep device via Bluetooth to control power, fan speed and timers remotely — no need to get up once you lie down.
Real-Time Schumann Resonance Display
The 7.837 Hz Schumann resonance status is shown in real time — visible the moment you open the app.
Music Control
Track selection, playback and volume — sleep music at your fingertips.
Breathing · Heart Rate
With a tracking device connected, view breathing and heart rate in real time to understand your body as you fall asleep.
Your ears can’t switch off — let natural soundscapes bury the noise.
Multi-Dimensional Technology · Clean Air
The Body No Longer Has to “Fight” at Night
Technical Specifications
Active purification plus passive filtration. Negative oxygen ions actively settle airborne particles; the composite HEPA H13 filter captures 0.3 μm particles at 99.97% efficiency, while modified activated carbon adsorbs formaldehyde and odors. Ozone concentration <0.003 mg/m³ — below 1/30 of the national standard.
What It Does for Sleep
When PM2.5, dust mites and pollen enter the airways, the immune system stays on low-level “alert” during sleep — more light sleep, less deep sleep. With clean air, the body can stop dividing its attention and finally sink into deep sleep.

- Eco-friendly ABS+PC material with a delicate touch that resists yellowing over long-term use.
- 18.4 dB operating noise — about the sound of a single leaf falling to the ground.
- Control: app / voice / touch / remote — no need to get up before bed.
- Smart light sensing: the indicator dims automatically when the lights go off, keeping the bedroom dark.
18.4 dB — the sound of a falling leaf, barely noticeable on the nightstand.
