An electroluminescent earphone with a bending-resistance and a high-brightness includes earphone wires having bending-resistant electroluminescent wires, earbuds, an electroluminescent wire driver and an audio inputting plug. Each bending-resistant electroluminescent wire includes: a plurality of central electrodes; a luminescent layer coated on outer surfaces of the central electrodes; a transparent conductive layer coated on an outer surface of the luminescent layer; an outer electrode made of a plurality of wires arranged on an outer surface of the transparent conductive layer; and a transparent plastic covering the outer electrode and the transparent conductive layer. The bending-resistant electroluminescent wire is parallel with an earphone audio wire or coils around an outer surface of the earphone audio wire. A colored transparent plastic covers the bending-resistant electroluminescent wire and the earphone audio wire to form the earphone wire having the bending-resistant electroluminescent wire.
