"Cardioid" is a type of mic.  "Binaural" is a mic pattern.

backwards...
Cardioid is a polar pattern.  Binarual is a recording technique where a "head", either real or manufactured, complete with ears...is used.  the mics are placed in the ear to employ the outer ear and physics combined.  Mics are omni-directional (just like your ear).   Playback is meant to be done via headphones only.
