Japanese company Landport launched the Cube, a speaker that's small enough to fit in the palm of your hand. Perfect for fans of extreme portability, Cube Speaker measures 26mm on all sides and weighs 16 grams. It has an output of 0.8 watts and connection to source of music such as media players is via 3.5mm jack, so it can accommodate a range of devices.

The Cube Speaker has a built-in lithium-ion battery that is charged via USB connection to a computer. A total of two hours charging is equivalent to four or five hours of playtime. To be available in black, white and pink, Landport's Cube Speaker will start shipping this December in Japan for $25 a pop. No word yet on global availability.
