Belkin’s RockStar is a star-shaped audio hub that lets you and your friends to connect iPods or any other MP3 players and headphones. With this hub you can share and mix music with your friends. Users can hear either a single song, or multiple songs mixed together.
There are 6 ports out of which one port is input-only, the other five can be toggled between input and output. The Belkin’s RockStar will be available in March for $20. This is a really cool hub but not great for me because my friends tastes don’t match up with mine.
