 Date: July 29 th , 2025 Federal Communications Commission Office of Engineering and Technology Laboratory Division 7435 Oakland Mills Rd. Columbia MD 21046 Subject: Request for Confidentiality Ref: FCC ID numbers To whom it may concern: Pursuant to the provisions of Sections 0.457 and 0.459 of the Commission’s rules (47 CFR §§ 0.457, 0.459), Apple Inc. hereby requests confidential treatment for documents filed with the Commission in connection with the application for equipment authorization referenced above. Long-Term Confidentiality Apple Inc. requests that the Commission withholds the following documents from public viewing indefinitely: • Block Diagrams • Electrical Schematic Diagrams • BOMs • Technical Descriptions • Antenna Gain, Antenna Specifications • Tune-up Procedure • Software Security Description These documents reveal detailed technical and design information that is protected by Apple Inc. as confidential and proprietary trade secrets. This information has been disclosed to those required to maintain its confidentiality and is not customarily disclosed to the public even after commercial release of a device. As a result, disclosure of this information by the Commission would harm Apple Inc. by giving competitors an unfair advantage even after commercial release of the device. Short-Term Confidentiality In addition to the above mentioned documents, pursuant to Public Notice DA 04-1705 of the Commission’s policy, in order to comply with the marketing regulations in 47 CFR §2.803 and the importation rules in 47 CFR §2.1204, while ensuring that business sensitive information remains confidential until the actual marketing of newly authorized devices, Apple Inc. requests that the Commission withholds the following documents from public viewing for one hundred eighty days after the date the grant of equipment authorization is issued: • External Photographs • Internal Photographs • Test Setup Photographs BCG-A3063 BCG-A3064 BCG-A3122 Apple Inc. One Apple Park Way Cupertino, CA www.apple.com  • User Manual These documents reveal technical and design information that has not been publicly disclosed in marketing materials and is protected by Apple Inc. as confidential and proprietary trade secrets. This information has been disclosed to those required to maintain its confidentiality and is not customarily disclosed publicly prior to the commercial release of the device. As a result, disclosure of this information by the Commission prior to commercial release would harm Apple Inc. by giving competitors an unfair market advantage. Apple Inc. believes the period of confidentiality requested is necessary to protect the information until the commercial release of a device. It is our understanding that measurement test reports and FCC ID label format cannot be granted as confidential documents and this information will be available for public review once the grant of equipment authorization is issued.

The tissue was placed in a nonmetallic container. Trapped air bubbles beneath the flange were minimized by placing the probe at a slight angle. 3) The complex admittance with respect to the probe aperture was measured 4) The complex relative permittivity ε ’ can be calculated from the below equation (Pournaropoulos and Misra): where Y is the admittance of the probe in contact with the sample, the primed and unprimed coordinates refer to source and observation points, respectively, ,  is the angular frequency, and . Figure D-1 Note: Liquid recipes are proprietary SPEAG. Since the composition is approximate to the actual liquids utilized, the manufacturer tissue-equivalent liquid data sheets are provided below.

FCC ID: BCG-A3063 SAR EVALUATION REPORT Approved by: Technical Manager DUT Type: APPENDIX E Page 1 of 1 Wireless Earbuds A P P E N D I X E : S A R S Y S T E M V A L I D A T I O N Per FCC KDB Publication 865664 D02v01r02, SAR system validation status should be documented to confirm measurement accuracy. The SAR systems (including SAR probes, system components and software versions) used for this device were validated against its performance specifications prior to the SAR measurements. Reference dipoles were used with the required tissue- equivalent media for system validation, according to the procedures outlined in FCC KDB Publication 865664 D01v01r04 and IEEE 1528-2013. Since SAR probe calibrations are frequency dependent, each probe calibration point was validated at a frequency within the valid frequency range of the probe calibration point, using the system that normally operates with the probe for routine SAR measurements and according to the required tissue-equivalent media. A tabulated summary of the system validation status including the validation date(s), measurement frequencies, SAR probes and tissue dielectric parameters has been included. Table E-1 SAR System Validation Summary NOTE: While the probes have been calibrated for both CW and modulated signals, all measurements were performed using communication systems calibrated for CW signals only. Modulations in the table above represent test configurations for which the measurement system has been validated per FCC KDB Publication 865664 D01v01r04 for scenarios when CW probe calibrations are used with other signal types. SAR systems were validated for modulated signals with a periodic duty cycle, such as GMSK, or with a high peak to average ratio (>5 dB), such as OFDM according to FCC KDB Publication 865664 D01v01r04.
