A charging case for charging and storing a pair of earbuds is provided. The charging case comprises: a case body having an upper section and a lower section, the lower section housing at least a battery and a PCB, the upper section having a pair of sockets to accommodate the pair of earbuds, respectively; and a USB cable comprising a distal end portion including a USB connector, a cable body housing electrical wires coupled to the USB connector, and a proximal end portion non-removably attached to the case body. The electrical wires are guided through the housing wall into an inner space of the case body where end portions of the electrical wires are soldered onto the PCB. A recessed area is formed on the exterior surface of the case body to accommodate the attached USB cable while not in use.

A speaker device with equalization (EQ) control is provided, wherein the speaker device may be a pair of earbuds/earphones or a headset having a pair of headphones, comprising: an audio receiving port for receiving audio signals from an audio source, a circuitry comprising at least a processor and a memory, the processor being configured to execute one or more firmware or software programs to perform tasks for processing the audio signals, including equalization of the audio signals according to one of multiple EQ settings stored in the memory, a user input terminal for detecting a user input to select one of the EQ settings; and a pair of speaker drivers for emitting sound corresponding to the processed audio signals.

Cable assemblies include at least a first wire and a second wire. The wires are enclosed, using injection molding, by a respective layer of thermo-resistant material. During the injection molding, the first wire and second wire are kept substantially straight so as to avoid kinks in at least one of the first wire and the second wire that can develop subsequent to the molding if a wire is not substantially straight. The tension associated with the first wire and the second wire is kept within a predetermined range or below a predetermined threshold. The predetermined range/threshold depends on a temperature associated with the injection molding. The injection molding can provide a zip structure over the wires such that the zip structure can be zipped-together and zipped-apart to prevent entanglement of the wires when used by a user.

Preferred assemblies are directed to a cable assembly that includes a first electrical wire and a second electrical wire; with a thermo-resistant material that is molded around the wires. Zipper teeth are molded to the thermo-resistant material of both of the wires. The zipper teeth on the first wire are releasably attached to the zipper teeth on the second wire, and at least one reinforcing fiber is encapsulated with one of the wires.
