The R300-E system includes the metal BP-300 bodypack transmitter, which uses two AA batteries. The HM3 microphone is comfortable for extensive daily use, including long presentations. Using a headwork microphone helps to control audio feedback and provides consistent audio while the speaker moves naturally around the stage
