Sound bars, while not as sweet as candy bars,  are still pretty sweet. You get full, robust audio in a tidy package, sans all the clutter. Now the crisp convenience of a sound bar is available for your tablet, laptop, or smartphone with the Zooka ($90). A Bluetooth connection (or 3.5 mm jack) lets you quickly turn the iPad’s tinny treble and bass into substantial sound, and the rechargeable batteries deliver 8+ hours of audio goodness. With the lack of a nougaty center, though, candy bars still have at least one advantage.
