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: 2A2BYHE-060A) , it will be moved to the charging case. The details are asbelow: A. Side surface (A): The side surfacedoesnot provide enough physical space to fit the printing of the FCC certification No. according tobelow reference picture. B. Top cover (B): The top coverdoes not provide enough physical space to fit the printing of the FCC certification No. according tobelow reference picture. Conclusion: Based on the above description of area A to B, we conclude that the device isunquestionably too small for enabling the FCC certification No. to be printed onto any surface. We thereforerequest to move the FCC certification No. to the charging case. Label: Best regards, Signature: YanfengZhang Manager

According to KDB 447498 D04 Interim General RF Exposure Guidance v01, clause 2.1.3.1-SAR-Based Exemption: A more comprehensive exemption, considering a variable power threshold that depends on both the separation distance and power, is provided in § 1.1307(b)(3)(i)(B). This exemption is applicable to the frequency range between 300 MHz and 6 GHz, with test separation distances between 0.5 cm and 40 cm, and for all RF sources in fixed, mobile, and portable device exposure conditions. Accordingly, a RF source is considered an RF exempt device if its available maximum time-averaged (matched conducted) power or its effective radiated power (ERP), whichever is greater, are below a specified threshold. This exemption threshold was derived based on general population 1-g SAR requirements and is detailed in Appendix C.
