Kerchoonz K-Box Speaker
One of the problems with speakers is the fact that their size often forces you to leave them at home. Not so with the Kerchoonz K-Box Speaker ($75). At just 4.5" x 2.2" x 0.8", this diminutive speaker can be hooked up to practically any audio source, and uses patented gel-audio technology to turn any flat surface — like a table, wall, or box — into a full-on speaker with surprisingly good bass response. Sure, it's not going to replace a portable Hi-Fi, but for places that you don't want to take your normal portable system, it's better than nothing.
