The uni-directional electret condenser mic element offers over 6 dB side and rear rejection from 100 Hz to 10 kHz.

Using the Clear-Com GM-18 is easy. First, connect the microphone to your compatible device using the locking 3-conductor quarter - inch phone plug connector. Make sure it's firmly plugged in to avoid any audio issues. Position the microphone so that the speaker is facing the front of the mic for the best sound quality. When using it outdoors or in a windy environment, put on the included windscreen to reduce wind noise. As for maintenance, keep the microphone clean by gently wiping it with a soft, dry cloth. Avoid getting it wet or exposing it to extreme temperatures. If you're not using it for a long time, store it in a dry and safe place. Also, be careful when adjusting the gooseneck to prevent any damage.
