The housing 101 includes a lid 103 at a bottom portion thereof. The lid 103 is attached to the housing 101 via a hinge structure 115, which enables the lid 103 to be opened and closed. As can be seen in FIGS. 7, 8 and 9A, when in an open position, the lid 103 provides access to the cavities 123-1 and 123-2 so that the earbuds 200-1 and 200-2 can be inserted and removed from the housing 101.

The device 100 further comprises a female connector 113 electrically connected to the battery 130 via the PCBA 135 and one or more of the wires 132. The female connector 113 is configured for receiving, for example, a male micro-USB connector, a male USB-mini connector, a male USB-C connector, a male lightning connector, or other type of connector that is connected to a power source, such as, for example, a standard household outlet providing 15 amperes (amps) of current and 120 volts. The male connector inserted into the female connector 113 may be connected to the power source via an electrical wire plugged into a universal serial bus (USB) adaptor that is plugged into the standard household wall outlet. The battery 130 of the device 100 is able to be charged via the female connector 113 when connected to the power source.
