Where are the wireless earphones?

All of my friends were fascinated by this new "invention" and forwarded me this picture that what a great idea it was.


Come on! Is that all they could come up with in 2008? This is the 21st century. Why do I still have to trouble with the cords, where the hell are the cheap, commodity bluetooth earphones? It wouldn't only mean less problem with the cables, but for instance with a wireless device two, three or more person could also listen to music from the same mp3 player at the same time without disturbing others. In my opinion this button clip was 10 years late...
