I have an idea for an audio product what should I do?

Kickstarter has a cool program 

Kick starter works good sometimes 

It didn't get the battery powered ESL headphones off the ground.

@dekay Careful building one to sell.

I doubt if Kenjit did a proper patent search.

I'm worried you may not know exactly what you are looking at. I assume when you say digital amp you mean a class D amp. But class D is not digital. It is analog. It is a form of encoding music wave forms into square waves but this is an analog encoding format, not at all digital.

Shark Tank wants a working product and, above all else, sales!
