Best for Travel: Libratone Zipp

The omnidirectional Zipp, which comes clad in one of several wool covers, churns out surprisingly rangy, room-saturating audio. But the three-speaker system's biggest selling point is portability: It's able to stream tunes wirelessly via an ad-hoc connection when you're off the grid. [Libratone Zipp $400; libratone.com]
