I have these headphones. I have not found a replacement cable solution that does not require soldering. The cable looks standard, but it's not. All 3 ends are 3.5mm Stereo, and the "T" is not for a Mic, but rather just a way to plug in another set of headphones. Like a built-in Y cable. Here's where things get interesting. The cable splits left and right signals and wires them to the "ring" connector on each of the plugs that go into the speaker shells. This prevents the cable that ssddx suggests from thatcable from working. It also makes it easy to reverse L and R as it's not labeled on the cable. The "right way" to repair this cable is to get a 3.5mm stereo Y cable (which I cannot find) and to rewire the left headset internally to move the wire from Ring to Tip. That would make it both possible to use plain cables, and it would also provide left and right regardless of how the headset cables were connected. Another way to repair it is to use the first cable suggested by ssddx and then rewire both headsets internally from ring to tip. Unlike the original cable, the one ssddx suggests has red and white plugs that are easily identified as R+L.
