They are virtually identical. Same basic mic element, case etc.
We took over manufacturing this when Heil discontinued his OEM version
suddenly. Apparently he had purchased a group of excess mics and had
replaced the dynamic element with the Electret element. (Leaving the
unused dynamic element unused inside the case.) When he ran out he
suddenly stopped selling them, so we had to locate the manufacturer of
the plastic cases and spec our own custom version.
For our MH2, the only changes were to eliminate the unused dynamic
element left inside the case by Heil, and to improve the foam mounting
for the electret element for better mechanical support. Overall the two
mics sound identical. We've bought a very large quantity of these and
they will be around for some time. :-)
