Sometimes on the bus I notice how the iPod Age has really put everybody inside his or her own head, oblivious to everyone else around. Headphones on. No one talks. Also, when I see somebody really rocking out, I wonder what music it is that?s turning them on so. I found one company here at CES that apparently has been thinking along the same lines.
The Jook, made by Razor, is an MP3 player add-on that allows people to share the music on their players.

The device, the company explains, attaches to your MP3 player (iPod, Zune and others) and uses a new tech standard to transmit one player?s music to another player nearby, provided there?s a Jook attached to that one too. With a punch of a button attached to the headphones, you can stop broadcasting your music and tune into someone else's broadcast. Another punch of the little button allows both parties to listen to the same music together.
The device also allows you to make a personal profile (music tastes, etc.), store it, and beam it to other Jook users. Pretty cool.
