Wirear- A revolutionary design for the hearing aid

Miss Sun Kyung Sunwoo came up with this design in 2007 and was shortlisted in the James Dyson Awards.  Why aren't we seeing cool hearing aids like this on the market. Plenty of room in there to put all the electronics you could want and a nice unapologetic style that says more mp3 player then peg leg.
