What is claimed is: 1. A headphone comprising: a first headphone assembly corresponding to one of the left and right ears; a second headphone assembly corresponding to the other of the left and right ears an input cord for connecting to audio-video equipment; and a bridging cord for bridging the first headphone assembly and the second headphone assembly, wherein the first headphone assembly comprises: a first speaker, a first cord winder device for winding up the input cord, and a first housing for housing the first speaker and the first cord winder; and wherein the second headphone assembly comprises: a second speaker, a second cord winder device for winding up the bridging cord, and a second housing for housing the second speaker and the second cord winder. 2. A headphone according to claim 1, further comprising: a first projection protruding integrally from the exterior of the first headphone housing and having a first hole formed thereinside; a first reel lock lever that pivots around a first axis and has, on one end thereof, a first catch for locking a first winder reel of the first cord winder device accommodated in the first headphone housing and a first reel lock cancellation portion on the other end thereof with respect to the first axis; a first torsion spring for biasing the first catch of the first reel lock lever in a direction so as to lock the first winder reel and allowing the first reel lock cancellation portion to enter the first hole formed in the first projection; a second projection protruding integrally from the exterior of the second headphone housing and having a second hole formed thereinside; a second reel lock lever that pivots around a second axis and has, on one end thereof, a second catch for locking a second winder reel of the second cord winder device accommodated in the second headphone housing and a second reel lock cancellation portion on the other end thereof with respect to the second axis; a cam pin that moves forward and backward in the second hole formed in the second projection and has a tapered cam portion for pivoting the second reel lock cancellation portion of the second reel lock lever in a direction so as to unlock the second winder reel; a compression spring for biasing one end portion of the cam pin to protrude out from the second hole formed in the second projection; and a second torsion spring for biasing the second catch of the second reel lock lever in a direction so as to lock the second winder reel and allowing the second reel lock cancellation portion to enter the vicinity of the tapered cam portion formed in the cam pin in the second hole formed in the second projection; wherein, when an input plug attached on the distal end of the input cord is inserted into the first hole formed in the first projection, the input plug pushes the first reel lock cancellation portion of the first reel lock lever against the first torsion spring and unlocks an engagement of the first catch onto the first winder reel, thereby winding up the input cord into the first cord winder device accommodated in the first headphone housing, and when the cam pin is pushed into the second hole formed in the second projection against the compression spring, the tapered cam portion formed in the cam pin pushes the second reel lock cancellation portion of the second reel lock lever against the second torsion spring and unlocks an engagement of the second catch onto the second winder reel, thereby winding up the bridging cord into the second cord winder device accommodated in the second headphone housing. 3. A headphone according to claim 1, further comprising: a first projection protruding integrally from the exterior of the first headphone housing, having a first extrusion pin formed protrusively from the exterior surface thereof and a first hole formed thereinside; a first reel lock lever that pivots around a first axis and has, on one end thereof, a first catch for locking a first winder reel of the first cord winder device accommodated in the first headphone housing and a first reel lock cancellation portion on the other end thereof with respect to the first axis; a first torsion spring for biasing the first catch of the first reel lock lever in a direction so as to lock the first winder reel and allowing the first reel lock cancellation portion to enter the first hole formed in the first projection; a second projection protruding integrally from the exterior of the second headphone housing and having a second hole formed thereinside; a second reel lock lever that pivots around a second axis and has, on one end thereof, a second catch for locking a second winder reel of the second cord winder device accommodated in the second headphone housing and a second reel lock cancellation portion on the other end thereof with respect to the second axis; a second torsion spring for biasing the second catch of the second reel lock lever in a direction so as to lock the second winder reel and allowing the second reel lock cancellation portion to enter the second hole formed in the second projection, wherein, when an input plug attached on the distal end of the input cord is inserted into the first hole formed in the first projection, the input plug pushes the first reel lock cancellation portion of the first reel lock lever against the first torsion spring and unlocks an engagement of the first catch onto the first winder reel, thereby winding up the input cord into the first cord winder device accommodated in the first headphone housing, and when the first extrusion pin formed protrusively from the exterior surface of the first projection is inserted into the second hole formed in the second projection, the first extrusion pin pushes the second reel lock cancellation portion of the second reel lock lever against the second torsion spring and unlocks an engagement of the second catch onto the second winder reel, thereby winding up the bridging cord into the second cord winder device accommodated in the second headphone housing. 4. A headphone according to claim 2, wherein when the input cord is wound up into the first headphone housing, a plug sleeve formed to have a predetermined diameter at the front edge of the input plug or a salient portion protrusively formed to have a predetermined diameter on the mold-formed portion of the input plug is inserted into the first hole formed in the first projection. 5. A headphone according to claim 3, wherein when the input cord is wound up into the first headphone housing, a plug sleeve formed to have a predetermined diameter at the front edge of the input plug or a salient portion protrusively formed to have a predetermined diameter on the mold-formed portion of the input plug is inserted into the first hole formed in the first projection.
