Welcome to the forum @Bigtwin! Oh wow! I’d never even heard of Hohner Hoodoo Hand wireless mic! Found this vid:
I don’t think there are any other ring mics as sleek as this. As far as the wireless component, there’s tons of wireless units you can use with a regular mic, but never seen an actual mic as streamline as this. Weird that I’ve never heard anything about this before.
As for the Suzuki HMH-100, I’d never heard of it before either. Not wireless, but that’s easy to address. Certainly a lot cheaper than my Beyerdynamic m160 (which I LOVE and use held against the harmonica for any clean recording that doesn’t require the use of hand wah.) Here’s Flip Jers talking about the Suzuki.
Sounds beautiful! When I play at church, I just use my vocal mic (I wireless Sure SM-58.)
