Close-talking" microphones are designed for use in very noisy 
environments, like military aircraft.They are not directional, rather 
they cancel all sounds more than an inch or two from their element. They 
are NOT "pleasant" sounding mics, they tend to be kind of raspy, their 
sole performance objective enough noise rejection that you can 
understand speech. When you hear speech from copters and similar 
environments, you're usually hearing one of these mics.

40 years ago, when I was doing a lot of live recording and also selling 
Shure products, they gave me an experimental mic with this sort of 
design that might be used for vocals by drummers. It sounded varying 
degrees of awful. :)  Shure is a VERY good microphone company, based 
in/near Chicago.
