According to the FCC regulation, the FCC certification No. should be printed on the earbuds, but as the earbuds are too small to print the label (FCC ID: 2AQ3A-BTN10L) , it will be moved to the user manual and charging case. The details are as below: A. Side surface (A): The side surface does not provide enough physical space to fit the printing of the FCC certification No. according to below reference picture. B. Top cover (B): The top cover does not provide enough physical space to fit the printing of the FCC certification No. according to below reference picture. Conclusion: Based on the above description of area A to B, we conclude that the device is unquestionably too small for enabling the FCC certification No. to be printed onto any surface. We therefore request to move the FCC certification No. to the user’s manual and charging case. Label: Best regards, Signature: Printed name: Zhibao Deng Title: Product Director
