Ask nearly any iPod enthusiast and you'll find that the Bose sound dock is the best speaker system you can buy. The only limitation is that the speakers aren't portable with a large power supply and cord. The new Bose soundock portable solves this problem with all of the power and punchy sound of the original model. This is simply the best sounding speaker system available for your IPod and it's portable. These speakers come with a high price tag; at $399 retail you're not only paying for great sound but the Bose name at the same time.

You have a choice of two colors with the sound dock portable: black and glossy white. The portable unit is small enough to travel with easily and measures 12 by 6 by 5 inches. It weighs just over five pounds and looks very similar to its cousin the original sound dock except for its swiveling iPod dock that protects the dock when traveling with the unit.

The portable model has a simple design just like the original sound dock and lacks physical controls aside from the two volume controls. The infrared remote include has eight rubber buttons that control volume, playback, play lists, and power. The included remote control is small and simple, but it's rubber buttons are easy to operate. The remote control works by infrared light; however it works well enough to control your iPod from nearly any angle in a large room.

There are two connectors on the back of the unit; one analog input and a plug for the power charger. There are no USB ports or video outputs. The speakers are powered by a lithium ion battery pack that holds a charge for up to eight hours of normal usage. At its loudest volume settings the soundock operates for about three hours. The battery holds its charge for a very long time for considering the speakers power and the amount of bass it produces.

The only flaw I can find in the speaker's design is the sensitivity of the volume controls; however, the included remote functions well enough. The sound dock charges your iPod whenever plugged in; charging the iPod will deplete the soundock's batteries at a much faster rate. The bass port on the back of the speakers also functions as carrying handle. Bose calls it the unit's Wave Guide Exit.

The Bose soundock portable has an LED light behind the speaker grill that lights up when using the remote control and flashes when the battery is depleted. One problem with the portable unit is that if you leave it unplugged for fourteen days you can only turn your speakers on by plugging the charger in. There are no iPod dock inserts included with the speakers so you'll have to use the one's that came with your iPod; however, replacement inserts are available from the Apple store. The power cord has a built in cable winder that makes it easy to travel with; however the plug is large and takes up a lot of room. With a $399 retail price tag it is well worth your while to comparison shop online for sites with the lowest prices and free shipping. There is an optional carrying case but you'll have to shell out $60 more for that.
