When Logitech announced its new Mini Boombox back in November, our advice was to give the portable speaker a listen before handing over your money. The advice wasn't due to any personal vendetta against Logitech, rather, it had everything to do with company's claim that the tiny speaker could offer an "immersive sound experience" for just $99.99 — a quote attributed to Azmat Ali, Logitech vice president of tablets and mobile in the accompanying press release. That's a bold proclamation for a device measuring just 4.55 x 2.8 x 2.28 inches and weighing half a pound. Fortunately, we received a unit in-house for review allowing us to put it head-to-head with our favorite battery-powered portable speaker, the Jawbone Jambox.
