    Valkee Light-emitting earbuds - "just crazy enough to work?"

    From Wired UK 2 years ago:

    I get a bit down in the winter, and I'm curious, but probably not $300 curious...

    This looks rediculous.

    There is nothing in your ear that can detect light as far as I know. If you want to save some money, rig up some LED's and allow the placebo effect to help you feel better for 3-4$.
