Dear customers
The internal structure of the product is complex, and a variety of vitality
parts are matched with each other. It takes a certain running-in period to
reach the ideal state designed by the engineer. During this period, you can
let the equipment work continuously for a period of time, or accumulate the
equipment to reach a burn-in time. The effect, in this way, can effectively
improve the delicacy of the sound, become mellow, smooth and elastic, and the
dynamics are more powerful, and the overall sense of vertical depth is also
improved. At the same time, the speaker’s performance can be adjusted during
the burning process. The angle is placed in the position, using theexisting
environment to achieve the best listening effect.
