I have never heard of them breaking either.
My friend even has one of the original Gurus with the analog knobs and that has had no problems ever.
I would guess if you took the old plug with you (3.5 mm) audio plug and you match it up to make sure it is exact, them all you need is a soldering iron to reconnect it.
If you don't have any experience with soldering electronics don't attempt it, just send it back.
