I'm looking for a dock extender cable that transmits audio. (I'm plugging a microphone into it with a dock connection.) I have a Lifeproof case, so am looking for the cable with a small plughead. There are tons of cables online with the big plughead, but i'm looking for one with the smaller head. (The bigger plug bends the dock door on the Lifeproof case, which I don't want.) The only thing I've found is this picture, and a visit to the website turns out to be a big plughead cable. suggestions?
