JBL On Tour Portable Music Box
Discriminating listeners who don't need seamless integration with their favorite player will appreciate JBL's $100 On Tour Portable Music Box. The curved, rectangular On Tour (6.8 by 3.8 by 1.5 inches and 12 ounces) slides open horizontally, revealing two 1-inch speakers. When you set it on a flat surface, the speakers point upward, presumably providing optimal sound. The On Tour has a minijack input instead of a true iPod connector, so you can use it easily with other players. (Check out if you want a perfect fit for your iPod.) Also, there's no remote or controls besides the volume up/down buttons.
Although perhaps a little tinny, the On Tour speakers sound pretty good for their size, cranking out decent bass and high-end sound at 100Hz to 20kHz and 3W per channel. You can run the speakers on four AAA batteries (rated life is 24 hours), or you can use the included AC adapter.
