I have not used this forum for a long time, since it was e-microphones. Due to moving home and office, travelling, and mostly misplacing things, I have several microphones for speech recognition. I also bought some long ago in an effort to improve accuracy. As I write I cannot find one of the Radio Shack mics I have a question about. I bought them over 5 years ago.
One is model 33-3012 which has a small pod with a button cell and an on-off switch. The model number is on both mic and pod so it was not added later. The other (which I cannot find) does not have the small pod and I do not have the model number. I will likely repost if and when I find it.
What does the pod do? What happens without the pod?
What is the difference between them?
