Need a little more bass in your place? Try out the iWoofer from Rain Design. With models fitting everything from the shuffle to the iPod video, you're guaranteed to get some bass satisfaction out of this. Dock your iPod and it can charge it, play back music through its 2.1 channel stereo system, or control the bass with precision. The iWoofer also adds FM radio to your iPod with channel memory and auto scanning. You can power the device with 4 AA batteries or you can use an AC adaptor if spending $10 a week on power isn't really your thing. Both the iWoofer or iWoofer nano will be available in mid-January for $129.
