Panasonic KX-TS730S Conference Phone

Two microphones at each of the four corners allows the unit to capture omni-directional voices at a distance. It is designed to receive audio in a 360 radius in rooms up to 380 square feet, so you can speak at a distance of up to 10 feet away and still be heard. This allows you to move about the conference room with the confidence of knowing that your voice will be heard clearly.
