It's a pocket-sized Bluetooth speaker for your MP3 player and a hands-free communication system for your car. Critics love the FoxL speaker, which, though no bigger than an eyeglasses case, transmits sound that's rich enough to please a cranky audiophile. Wirelessly tether it to your cell phone, take it along in the car, and a built-in microphone allows you to handle phone calls on the road. (Note: The Bluetooth streaming feature works on any A2DP-compatible device; Apple has not turned on the protocol for the iPhone so you need to use a standard audio cable.) Price: $249
