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.
