iPod speakers are either portable, which you can carry around, or home models, which you cannot carry around because of some restrictions like, it is bigger and heavier and is therefore not handy, and it is not battery operated and work only when plugged into an electrical outlet.

The portable models are battery operated and has a size just slightly larger than iPod Nano and some weighs only half an ounce! Although portable iPod speakers offer sound better than most computer speaker, it can't compete with the home only or standalone iPod speakers that can produce louder, crisper, and more booming sound, for these iPod speakers get their power directly from an electrical outlet that gives much energy compared to a low voltage battery.

Below are the best in iPod speakers that could rock us out of our seat with their booming sound.

-iBlasting the Room with iBoom speakers

iBoom is the newest speaker from DLO. The iBoom speakers sport an amorphous shape and has a slot in the front which serve as a hub for iPod or iPod mini. The four speakers only need 20 watts per channel to start producing sound. iBoom iPod speakers also has a built-in handle, an AUX in port, and can run either on AC power or a with six "D" batteries. When plugged in to an AC power, the iBoom iPod speakers will charge the cradled iPod. Design wise, iBoom speakers look pretty good with a white iPod cradled on it.

The plus points for iBoom are (1) low wattage consumption but could still produce decent sound, (2) portable and (3) charge an iPod when it is running on A/C power.

- 'What's the new Black?'

For Altec Lansing, the answer is still black.

Altec Lansing's inMotion iM3 iPod speakers come in the usual Apple white and, now, in black. It weighs around 15 to 16 ounces only and is sized just a bit larger than the iPod.

Altec Lansing is known for creating sound system that could produce sounds in different ranges from the highest pitch to the lowest bass. And now that Altec Lansing has speakers for the iPod, expect that these would be of high quality. In fact, these speakers has a class D amplifier to create rich, audible sounds.
