The Workman DM502B Desk Microphone was recommended to me and I gave it a try. This is a well built microphone. Nice style, easy to key up and gooseneck adjustment. Mainly bought this microphone just for the gooseneck & microphone. This was rewired to a home made microphone system of mine. The Workman DM502B microphone section wired to a Galaxy Roger Beep/Echo Base Station Microphone pre amp create awesome results. Add a acoustic windscreen over the microphone head and you got yourself a real talker!
