Randal, >>>>>>>>>>>>>>>>>>>>>>>>>>>>>> Where did you buy the Telex M-560? >>>>>>>>>>>>>>>>>>>>>>>>>>>>>> The Telex M-560 has been discontinued. We have tested it and carried it for several years but was not sorry to see it go. It was considerably less accurate than any good headset microphone or hand-held/desktop mounted microphone. We only carried it because there were some people with disabilities who could not afford a better microphone and had no choice but to use a desktop microphone. If you need a desktop mounted microphone consider one of the Sennheiser hand-held microphones mounted in a Balanced Microphone Arm. The only trick to using one of these microphones is to not turn your head as you dictate. The iListen people recently tested one and found it to work quite well.

With this microphone you would have anywhere from 30 to 50 fewer corrections when doing large amounts of dictation daily.
