No lie, Monster’s portable blaster caught us by surprise during our hands-on test. The loud volume levels and superior audio quality are surprisingly effective in spacious environments. Speakerphone capability is cool, but the Micro’s voice command system steals the show: totting over two-dozen voice prompts that handle phone functionality. Its slim form factor makes for a snug fit in-pocket, too.
