Please be cautious, particularly with links and attachments. *** Inquiry on 12/13/2019 : Inquiry: Good day! Please kindly check the attached TWS earphones. They are very small and the FCC ID number is impracticable to put on the product. According to 2.925(f) as below, We will put FCC ID on the user manual instead of the label on the product. Thank you! §2.925 Identification of equipment. (f) The FCC Identifier including the term “FCC ID” shall be in a size of type large enough to be readily legible, consistent with the dimensions of the equipment and its label. However, the type size for the FCC Identifier is not required to be larger than eight-point. If a device is so small that it is impractical to label it with the FCC Identifier in a font that is four-point or larger, and the device does not have a display that can show electronic labeling, then the FCC Identifier shall be placed in the user manual and must also either be placed on the device packaging or on a removable label attached to the device. FCC response on 12/13/2019 Yes we will accept according to 2.925(f). 2 Attachment Details: TWS earphone external photo Do not reply to this message.
