Oh...I feel your pain.
I myself was a recent owner of the TF10s.
And I did that to my IE6 not too long ago by a careless accident.
Unfortunately, the cables weren't removable and I destroyed more than just the connecting parts
I'm quite sure the wiring isn't complicated and could be easily fixed at a local electronic store.
Or you could probably even do it yourself if you have any soldering experience.
I don't know anything about the reshelling part.
I would try to find someone good with soldering iron to solder it back on because you dont have stuck pins, even if soldering the connector back doesnt go well the drivers are still unaffected. The price of reshelling cost more than the iems themselves, and for the cost you can purchase a new pair of different, or look around for a pair of used triples
