Someone posted a while back asking about a good, high-quality set of portable, battery-powered speakers to use with the BookPort while traveling. I found the below set at Radio Shack for $100, and I know they're cheaper online. Try putting the name in Google and see what you find. They are literally pocket-sized and sound absolutely marvelous! Great bass response and the DoubleTalk sounds fine, too. HTH Sarah *** JBL On Tour Speakers The heavyweights of speakers have brought out the JBL On Tour to bring the quality of home stereo systems to those on the road. Featuring easy-to-use touch controls, computer optimised equalisation and advanced energy management systems, the On Tour combines the rich sound of the stage with ultimate portability. The On Tour will provide astonishing bass and clear accurate sound from a pocket sized system. In addition the system has an automatic battery saving shutoff. The AEMS will automatically put the system into sleep mode when the cover is closed or when there is no audio input. The On Tour awakens with just a touch and resumes at the same volume level when the cover is opened or the input resumes. The JBL On Tour is designed to use most types of AAA batteries. Four fresh AAA batteries provide over 24 hours of continuous play at normal to high listening levels. An amber LED flashes when the battery protection circuit senses the batteries are low. Just a touch on the volume control pads increases or decrease the volume. A touch on both pads mutes or un-mutes the system. JBL On Tour also remembers your last volume setting even after the system shuts down.
