wire snap at terminal where wires converge into one.

My ibeats headphones cable has snapped at the poimt where it goes inside the part where the wire goes into one cable from two cables. So from buds down the wires into the point where they go into one cable and down to the jack its he point that they converge where its snapped inside a little black box. Is there anyway I can fix this easily or not as apple wont repair them for me or will do for an extortionate price. Pls contact me at zebede@mail.com
