• 关于运费：
  When placing a large order, it is recommended to choose freight logistics for cost-effectiveness. For smaller orders, general delivery services are more convenient. Wholesale prices do not include the cost of goods shipping, which is paid by the buyer. The specific shipping cost is determined by the weight of the wholesale goods at that time. The calculation of shipping costs is based on the total weight of the goods, not a fixed price for each item.
  
  Receiving and Inspection:
  Please inspect the goods before signing for them. To ensure the safety of the transportation, we carefully pack the goods before shipping. If there is a problem due to carelessness in not inspecting and signing for the goods, the buyer will bear the responsibility.
  
  Frequently Asked Questions:
  Interference: The microphone is powered by batteries, and a slight current noise caused by magnetic interference is normal. Generally, only a very low current noise is heard in the silent mode. When playing music normally, the noise is not noticeable. If the noise is too loud or suddenly appears after playing for a while, it is likely that the battery is about to run out. Please charge the battery.
  Do not play: Please charge again.
