Ever wish you had something that was virtually identical to Jawbone’s snazzy battery-powered Jambox Bluetooth speaker, just… bigger? Your wish is their command! The company has just announced the oh-so-aptly named Big Jambox, which comes in at almost double the original’s size in every dimension. The new, bigger, beefier brother offers a 15 hour battery life (versus 10 on the smaller guy), drastically boosted audio quality, and support for things like conference calling (with a built-in omni-directional mic) and the surprisingly impressive LiveAudio 3d sound technology. The Big Jambox will cost $299, with pre-orders beginning May 1st and the first units hitting the shelves on May 15th. We’ll have a full review up in just a few days.
