iLuv have announced a new portable stereo speaker, the suppository-shaped iSP100. Promising "explosive sound", the iSP100 runs off of three AAA batteries and has two 2W speakers; although the company is positioning it as an iPhone or iPod accessory, a standard 3.5mm input means that it will work with any sound source.

The iSP100 will be available worldwide in late September 2008, priced at $34.99. It ships with a carry-case
