A portable Bluetooth speaker can be a magical thing. These wireless, battery-powered boom boxes can stream music from your computer or mobile phone, and many of them will even act as speakerphones for taking calls. The BluBridge mobile speaker ($99) from Miccus can perform all of these feats of wireless audio magic (and more) in a space no larger than a paperback book.
Measuring 8 inches wide by 3.5 inches tall and a little over an inch thick, the BluBridge mobile speaker uses a blade-like, tapered design that is small enough to throw in a shoulder bag, but not so small to fit in your pocket. The front includes two 1.25-inch speakers covered with a durable metal grille, along with a useful arrangement of plastic controls for power, volume, mute, and song playback (play/pause, skip, reverse).
On the back of the BluBridge, you'll find a battery compartment for four AA batteries, a line input jack for connecting non-Bluetooth audio devices (MP3 or CD players), and a DC power input for the included power adapter. A cloth pouch is also included with the speaker, along with a 2-foot line input cable.
