Abstract: A headphone cable and a plug thereof are provided. The headphone cable includes a first plug, a first microphone module, a first transmission line, a noise-cancellation module, and a second transmission line. The first plug has a first isolation portion with a first connector protruded thereon. The first connector is for plugging into a first headphone jack of a headphone. The first microphone module is disposed on the first isolation portion. The first transmission line has one end thereof connected to the first plug and the other end thereof connected to the noise-cancellation module. The second transmission line is connected to the noise-cancellation module and a playback apparatus. The noise-cancellation module generates a noise-cancellation signal to be combined with an audio signal being outputted to the headphone responsive to an environmental noise received through the first microphone module.
