The invention relates to the technical field of an earphone line material, and particularly relates to an improved elastic earphone line. The improved elastic earphone line comprises an elastic core line, a conductive layer woven on the surface of the elastic core line, and an elastic insulating protective layer arranged on the surface of the conductive layer in a sleeving manner, wherein the conductive layer is an elastically-telescopic net-shaped pipe woven by a varnished wire; and the elastic core line is prepared from the following components of SEBS, paraffin oil, silicone oil, PP, EPDM, P0E, PE, TPV, calcium carbonate, erucic acid, stabilizer and a stabilizing agent. By filling a co-mixture of PP / filling oil / SEBS with a toughening filler, the plastic is endowed with excellent elasticity; after the plastic is mixed with the paraffin oil for use, a synergistic effect is generated to endow the improved elastic earphone line with excellent elasticity; and in addition, the earphone line product prepared from the elastic core line can be excellent in flexibility and relatively long in extension length, so that the service life and the use effect of the earphone line can be prolonged and improved.
