Used in an environment where the mic has to be about 7-10 feet from the speaker, and it picks up just great. No hollowness, or ringing. LED's on the back of the unit keep one up to date with the charge status, and the db settings. We use it in a static position, but it does have the camera mount if the need arises to make it portable. We mount on a tripod withe the aid of the MY200 clothespin style clip.
