En.vinci.im

I was one of 6300 backers of the Vinci 2.0 version of their wireless headphones. After setting a pledge goal of $20,000 but receiving over $1.8 million between Kickstarter and Indiegogo, they recently announced that they cannot deliver the headphones for which we pledged. They also managed to blow through all the money and can't even deliver to us the previous version of the headphones, OR make good on their campaign promise to refund if the headphones weren't shipped. And yet they continue to take pre-orders. Avoid this company like the plague.
