I think that most people who listen to music on their iPod, notebook, or netbook will agree that most devices lack seriously in the bass department. Notebooks and netbooks are often worse than the iPod and other MP3 players.
DigiZoid has a new device called the zo personal subwoofer that promises to redefine personal music listening. The gadget is about the size of an iPod nano and promises to give the sort of bass you would normally get from a 12-inch subwoofer. That is a bit hard to believe.
The gadget connects to your media player or other device using the headphone jack and a supplied mini-stereo cable. The user then plugs their headphones into the output on the zo for improved sound. The zo gets power from an internal rechargeable battery. If you are intrigued, you can get your own zo for $99 right now.
