Landport from Japan has created the Cube Speaker that measures at only 26mm x 26mm. The speaker uses a lithium-ion battery that can be recharged via USB port for two hours to get a full charge. The fully recharge battery offers enough juice for two to five hours of audio. Available in white, pink, and black, the Portable Cube Speaker will be released in December for $25 in Japan.
