I'm definitely not going to drop any money on it, especially not $300, until I know more about the product. It seems like snake oil to me. However, I'm interested to see how it's reviewed as more information comes out! It would be cool if it worked.
Although I have to admit, it isn't something I'd be interested in owning even if it does work. It seems odd to me. I can't pin a difference between the purported effects of these headphones and something like drinking/smoking, which I actively engage in on the weekends, but I feel like the difference is there. Anyone else feel that way, or is it just me?
