Working Principles:

1.Sound stimulation: Sound stimulation promotes the secretion of melatonin by the pineal gland, reduces the secretion of adrenocorticotropic hormone, alleviates anxiety and promotes sleep.

2. Micro-electrical stimulation: Microcurrent stimulates the vagus nerve, inhibits neuronal excitation, and allows the brain to gradually return to calmness.  

Features:

1. Lightweight and portable: Bluetooth headset design, weighing only 25g.

2. Skin-friendly and comfortable, gentle experience: Uses medical-grade silicone material, friendly to the skin.

3. Dual-mode for sleep assistance: Sound stimulation + micro-electrical stimulation, efficacy doubled.
