Hey Phil, I am not sure of your sound tech nerdistry, but normally (in recording studio situations, not sure about the particular model you have) the diaphragm is on the side, not the top. And the rear diapragm is used to cancel out sound. What it picks up in the back, it councels it out from the front to isolate intended input and reduce background noise. Anyhow, I say all that to say, if the main diaphram is actually on the side, you are doing your voice a disservice. I see that some people are complaining about the audio quality of your voice on the podcasts, and I think that might be the culprit.
