Shipping
We are an online wholesale platform and shipping costs are charged separately for greater benefit to you.
Air freight costs are based on the weight of the product (including packaging bags and cushioning materials). For products under 2kg, freight is calculated in 50g increments. For products between 2kg and 4kg, freight is calculated in 100g increments. For products over 4kg, freight is calculated in 1kg increments.
If your order exceeds 4kg or the shipping cost exceeds $70, we recommend contacting our customer service for an accurate shipping quote. You will need to provide your zip code address when you contact us.
Air freight options include DHL, UPS, FedEx, and Yun Express, with a delivery time of 7-12 days.
When the weight of the express delivery exceeds 12kg or air shipping cost exceeds US$100 or sea shipping cost exceeds US$50, you can choose B2B shipping:
Air freight(10-14 days)
Yun quik boat sea freight (15-20 days)
Quik boat sea freight(20-25 days).

Product Description: Schumann waves do not directly improve sound quality in audio or video products. Instead, they affect the spatial environment, promoting relaxation, enhancing the body's perception of sound and images, improving work efficiency, and effectively relieving psychological stress. This product not only outputs a 7.83Hz Schumann wave but also allows frequency adjustment within the range of 0.1Hz to 30kHz. The digital circuit crystal oscillator frequency reference ensures greater stability and stronger anti-interference capabilities.
This product not only outputs a 7.83Hz Schumann wave but also incorporates programmable frequency modulation technology, allowing frequency adjustment within the 0.1Hz to 30kHz range. The digital circuit crystal oscillator frequency reference provides greater stability and stronger anti-interference capabilities. The power supply interface uses a DC 5.5*2.1 or Micro USB interface for convenient use; simply plug the USB end into a power bank, USB charger, or other USB-powered device to operate.
Antenna Waveform: Sine Wave
Interface Waveform: Sine Wave
Power Supply Interface: Micro USB
Power Supply Voltage: 5V
Rated Power Consumption: <1W
Default Frequency: 7.83Hz
Adjustment Range: 0.1Hz~30000Hz
Sine Wave Signal Voltage Amplitude: 3V
Square Wave Signal Voltage Amplitude: 5V
Circuit Board Size: Approx. 15*10CM
With Housing Size: Approx. 15.5*10.5*2.8CM
Frequency Change Method: Directly input the frequency and press the lower left corner key to complete the setting.
For example, press [7][.][8][3], then press [OK] to set the default power-on output to 7.83Hz. The setting range is 0.1~30KHz.
Usage Method: Take out the USB cable included with the product, connect it to the circuit board, and plug the USB end into a power bank, USB charging head, or other USB power supply device to operate. In terms of frequency accuracy, it can only reach 99%, with an error of less than 1%. To produce sound, you need to insert the audio jack into the amplifier or use headphones. The audio jack must be fully inserted.
