Comments about Toa Electronics PM660U Desktop Paging Microphone:
We use these in our studios for communication between the recorder and the reader. The ones that we originally had lasted us 15 years with no problems, until someone damaged the cable. The sound is clear and reliable and they hold up well with continual use!
