Congratulations on the new babies Ian!
FWIW, the owner before me that had the Links (that I owned for a short time) got a little over zealous when he pushed the connector together with the grommet on the body. One of the pins somehow became misaligned and he boogered up the plastic part of the female side of that connector just a little bit (can't remember if that was on the connector or the mic body).
I can't really figure out how he did it, but...
Just a lesson learned I'm passing along and maybe something to be a bit careful of...don't put alot of force on the connector unless you know the all of the pins are well aligned. Probably not a whole lot of reason to disconnect the cables anyway.
I think when I got them I asked others about this and it seemed to be a very isolated incident.
