They don't seem to be a scam - they were at CES and a prototype has been reviewed on cnet (http://www.cnet.com/news/earin-kanoa-wireless-bluetooth-earbuds/). They are sending email updates once in a while on their progress, and everything seems to be on track.
From what I've been reading, the consensus seems to be that the DA8 is slightly warm and very smooth, whereas the HA-1 is on the analytical side with a bit of roughness to the treble. I ended up getting the DA-8 and am very happy with it.
