With a capsule diameter of just 2.5 mm, Audio-Technica's MicroSet
provides the ultimate in low-profile, high-performance audio. This
omnidirectional condenser microminiature headworn mic offers an
ergonomic under-ear design: its flexible, lightweight contoured loop
hooks behind the ear for an ultra-secure, comfortable fit with or with-
out glasses.
Operation: MicroSet's flexible design
enables it to be worn on either the left
or right ear. Position the lightweight
contoured loop around the back of
your ear, so that the boom extends
from the bottom of your ear as shown.
Bend the loop as needed to achieve a
secure, comfortable fit, so that the
MicroSet is not dislodged by shaking
your head. Remove the MicroSet and
bend a gentle curve in the micro-
phone's boom. Hook the MicroSet
back around your ear, and adjust the
boom as needed to follow the contour
of your face, positioning the micro-
phone near the corner of your mouth.
MicroSet has a large acoustical sweet spot; experiment with
placement near the corner of your mouth for optimal performance.
A cable clip is provided for strain relief, allowing the MicroSet to
remain securely in place without the weight of the cable pulling on
the headset. To install the cable clip, slip the cable into the snap-on
connector and attach the clip to clothing, leaving enough slack on the
MicroSet side of the clip to allow for free, comfortable motion.
The donut-shaped moisture guard is provided to protect the
element from sweat and moisture.Position the moisture guard as
close to the element as possible to provide maximum protection. To
remove the moisture guard, first remove the element cover and place
it out of harm's way. Gently slide the moisture guard over the ele-
ment. Replace the element cover.
