Batboard

Hi everyone.

I got a bunch of JEDI Speaker Mics here and I'm not sure which is which.

NMN6191B - noise cancelling
NMN6193B - standard version

NMN6191C - no idea what the C stands for…
NMN6193A - comes with a ugly, sticky rubber PTT instead of solid plastic. where does this thing come from?

Thanks for your help!

The model revisions are just that, revisions. Just ignore the letter suffix to figure out what you have. I've been told that the annoying rubber button is to help make it weather resistant... that may not be the case.
