Radio Shack has just introduced another 49 MHz FM walkie-talkie set. Something that interests me about this one, though, is that it uses an "auditory microphone" -- that is, the ear piece is the microphone as well, picking up voice through the auditory canal. It seems to work "ok". The speech is intelligible, but not as good as it would be with a regular microphone. I'm wondering how well known or mature this technology is. Have auditory mics existed for a long time? If so, can somebody point me towards a source for them? I'd hate to have to pay $80 for R.S. stuff just to cannibalize the walkie-talkies for the mics if I could get better mics from someplace else for less.
