In Batman: The Dark Knight is never out of communication; with Alfred, with the Batfamily, with Oracle and of course with the Batcomputer. This in-suit communicator is comprised of a transmitter in the ear of the cowl and a receiver housed somewhere in the jaw slot. In Reality: These days bluetooth hands free kits are a common piece of peripheral kit for a mobile phone but while these help recreate the experience to a degree, its not quite there. Infinitely closer however are the TTMK IIIs used by military forces worldwide. These comprise of a specially made earpiece and a throat mounted microphone, completely negating the need for a visible mouth transmitter. All you need now is a usb adapter and youre Xbox Live's leetest gamer! Oh and the $525 needed to make owning this gadget a reality of course.
