Firstly - and only my opinion - I don't believe either of these mics is a ribbon...certainly not the Dynacord, which I'm pretty sure is a dynamic. The first one baffles me, but it looks like some kind of knock-off copy. It also has a 1/4" connector, which states it's a hi-Z mic (which I also don't think a ribbon would be, but I could be wrong). They're nifty looking anyway. I personally wouldn't buy them - even if they were incredibly cheap - but YMMV. Everyone has their own taste.
