Hello,
Currently I am using a Shure SM57 for my vocal duties, I like the mic but it's a bit limiting for my own mobility. Using it in a mic stand means I have to direct my vocals in that direction and having it in the and means not enough hands available for my synths.
So I'm thinking about getting a wireless headband mic like they use for presentations and the like, but I like screaming and shouting, is that an viable option or is the pickup in the mics way to sensitive?
Or are there other ways?

or the
Shure WH20
I am always recording my synths and vocals at the same time, so a recording session can be quite a cacophony of sound so it can't be too sensitive.
Ideas? Experiences?
