@rxscott63: I dunno … I think that the lanyard allows the mic to swing back and forth, hence the rustling noises.
On top of that problem is the fact that the mic diaphragm is quite a ways from your mouth, and low on your chest. It probably picks up noises situated there better than it picks up your voice.
I’m stretching for answers here, because I’m not very familiar with the unit: it’s big … much harder to position advantageously.
I’d try putting it into your shirt pocket, just to see if there’s any improvement at all.
Sorry for the delayed reply: I didn’t realize you were addressing me, at first.
[My hero, Red Green, and his sidekick Dave would duck tape the mic to the underside of the brim of a ball cap … problem SOLVED!]
