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.
