Yes they do.
The Micro Windjammer works purely by using a 22mm diameter double-sided adhesive pad with 9.5mm thru hole. This is attached to the body of the phone and or camera, and the fur disc (Windjammer) is then stuck on top.
Looking from the front of the iPhone 5C, the mic is on the base to the left of the home button.
