This page says that these are USB headsets. Replacing an USB connector (one that plugs into PC) is not a rocket science - it needs experience working with tiny cables. If you are brave - get a space charging USB cable, cut and expose the wires, do the same from the headphones side (close to the connector, of course), and connect them one-to-one: each cable should have black, red, white and green cables inside, so just twist same color wires, and insulate with sticky tape. If that works - find a friend, or a radio shop around you, where they can make permanent connection.
