Songistix has begun shipping an adapter that converts its Monsoon iM-700 speaker system’s 1/8-inch jack to a USB audio device, according to MacCentral. Monsoon’s site has not yet been updated to reflect the change. It’s unclear at this point whether the adapter will be bundled with systems from now on, or available on its own (pricing has not been set). The iM-700s carry a US$169.99 price tag, although they are typically available for significantly less through resellers.
