Review on Enhance Your Conference Experience with the SoundTech CM-1000 3.5mm Omni-Directional Conference Microphone by Marco Hubbard

I daisy chained three of these mics (one USB mic) to record a 3 week trial in a large non-acoustic courtroom on my computer and they did great is working. I could hear every word. There may be more sensitive mics out there, but for the price you can't beat them. The fact that they can be connected to each other makes them indispensable in large rooms. I highly recommend them.
