Apples and Oranges.
The Astatic D104 uses a crystal element (Hi-Z), while the Shure 444D uses
a dynamic element (Lo-Z). The response curve (sensitivity to specific
audio frequencies from 100 Hz to over 7,000 Hz) of a specific microphone
element makes a BIG difference in reproduction of the human voice.

The Shure 444 has a controlled magnetic element. My manual says it is
high impedance for high mic inputs. The 444D had an impedance switch on
the bottom for high or low the 444 does not.

CORRECT. My post for which Shure model number was truncated.
The later 444D model was switchable !!


I have both D-104 and Shure 444 and have tested them a lot on a Valiant
which has the audio mods. Most people prefer the sound of the D-104, but
the Shure is a close second.

Both great microphones. You can find Shure 444 and 444D microphones
surplus -- it was a very popular model for Public Address (PA) usage in a
variety of applications.
