Description

Descriptions:
Schumann wave itself is not directly acting on the sound or video products to improve the quality of sound quality, but the role of the space environment, peoples physical and mental relaxation, improve the bodys perception of sound and images, improve the health of the human body to improve the efficiency of work, mental stress also have a better effect.

Schumann wave applied to HIFI:
1. The player has a certain HIFI experience, HIFI equipment level can not be too low.
2. Can hear, the difference between the same system on the different wire to bring the tone changes.
3. It is recommended to buy two sets of trial (the effect is better).
4. when the product will be placed on the speaker, plus the appropriate weight for anti-vibration treatment.

Schumann wave applied to sleep:
1. It is recommended to buy a set of trial, on a bedside, more
