· Lightweight microminiature headset with ergonomic under-ear design · Terminated for use with all Audio-Technica UniPakTM wireless systems and many other manufacturers' wireless systems · Exceptional sound quality and rugged construction · Adjustable fit for left or right ear · Available in black, cocoa (-CO) and beige (-TH) models 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.
