The poor polar response of conventional microphones (shown in Figure

high sound level and extensive signal processing makes in-ear monitors
very uncomfortable to use. In contrast, those who use in-ear monitors with

The Proof is in the Using and in the Listening

It is often said, “Hearing is believing.” We are willing to back up our
claims and prove it. We invite you to contact us and arrange for a
demonstration of an Earthworks sound reinforcement microphone, so
you can experience these world-class microphones for yourself.

Earthworks High Definition Microphones™ utilize a number of new tech-
nologies that provide them with near-perfect polar response, greater rear re-
jection, substantially less off-axis frequency and phase errors, in addition to
extremely short diaphragm settling time, that will let you hear subtle details
that conventional microphones cannot capture. In addition, Earthworks mi-
crophones have very impressive transient and time domain response, and
do not have a presence peak. The Earthworks vocal microphones are nearly
flat throughout their extended frequency range. The extended high fre-
quency response adds to the outstanding clarity of Earthworks High Defini-
tion Microphones™. All of the above working together will provide vocalists
with a clarity previously unavailable. The Earthworks vocal microphones are
much easier for a vocalist to use and they don’t have to work the mic as hard.
For the sound engineer, the Earthworks microphones require very minimal,
