Mobile CD and DVD players, IPods, MP3 players and laptops will all be able to benefit from the ProMedia Ultra 2.0 system, a sound system that aims to provide dynamic sound in a portable package. Priced at $100, the ProMedia Ultra 2.0s pack 15 watts of power per channel, and intends to give the user desktop like sound quality on the move.

"Although they're a little unwieldy, the ProMedia Ultra 2.0s sound great. Compared with other portable speakers, the 10-inch-high satellites have superior imaging, crisp and detailed high to midrange response, and surprisingly good bass. They faithfully reproduced the airiness of Jeff Buckley's 'Hallelujah' and the detailed sound field on DVDs like 'The Fifth Element.'"

There are, of course, some drawbacks. The speakers certainly stretch the term "portable" a little, both in terms of their size and bulkiness, but also in terms of their inability to run from batteries, since they must be mains connected for operation. Still, a product for IPod and MP3 player owners to seriously consider.
