follow this steps and fix it. God bless you
Locate the faulty connection along your cord. Plug in your
headphones and play sound through them as you jiggle the cord at various points
to locate what part of the cord is cutting in and out.
Cut the cord using wire cutters an inch or so past where
the fault in the cord is. If this is at the connector, cut the entire connector
piece off. If it is near the headphones, cut off enough to eliminate the faulty
section and still allow the cord to be reconnected.
Strip the end of the cut cord. There are three wires in
the cord: the left channel, the right channel and the ground. The left and
right normally are colored, and the ground is bare.
To repair a poor connection where the cord meets the
headphones, match the wires with the correct leads coming from the earpieces
and twist them together. Wrap the wires with electrical tape.
To repair a bad connection at the connector jack, acquire
a new 1/8-inch connector and attach the cord's inner wires to the appropriate
points on the connector. Connect the left channel wire to the tip, the right
channel wire to the ring, and the ground wire to the sleeve. Solder all the
wires in place.
Connect the headphones to a sound source and test for
proper function. Jiggle the cord at the new connection to make sure it is
secure and does not cut in and out.
