Wow, expensive compared to more conventional solutions (eg wireless mic systems, although admittedly you have to use a receiver connected to the phone). And the marketing is a bit over the top - "Do you want to increase your likes, views, and subscribers on social media by ten-fold? " Heh, if only it was that easy! And SmartMike+ paired with cardioid polar pattern unidirectional mic. A Two-pronged approach completely eliminating unwanted background noise." Er - cardioid mics reduce off-axis pickup but no way do they "completely eliminate" it, even with a shotgun pickup. Anyway, interesting, thanks for bringing it to attention.
