Water, shock and dust resistant, it's extremely portable and can get surprisingly loud (5.7 watts) considering its diminutive size. Expect rich, crisp, midrange-focused sound -- eight hours' worth, to be exact, which is 50% more battery life than other speakers its size). An impressive 60-foot wireless range rounds out the benefits.
