Logic3 today announced the i-Station Traveller, its most portable speaker system yet for digital audio players. The four-watt stereo accepts input from the headphone jack of most jukeboxes, including Apple's iPod and numerous music phones. The company says the Traveller is powered completely by four AAA batteries and weighs just 5.5 ounces, although battery life is currently unrated. Intended to match virtually any device, the Logic3 speakers ship in six colors ranging from conservative black and silver to bright green and orange. All versions are planned for a late January release in the U.K. at a price of £20 ($40). A U.S. release is likely but has not been announced.
