I just received my CA-14 cardioid mics, and was experimenting with clipping them to my shirt collar, but nope. They're always pointing everywhere but forward. I thought about wearing a hat, but A) don't really want to wear hats to shows, and B) I also shoot video, so I'm often looking down at the viewfinder, which would impact the sound quality.
For those of you that use cardioid mics, please help me out here.
