Kubxlab, makers of the mOna iPad stand, introduced the Ampjacket, an acoustic amplifier case for iPhone 5, iPad mini, and iPod touch.

Kubxlab’s ampjacket acoustic amplifier uses its design to double the sonic volume of a device, without the need for extra power or batteries. Available for the iPhone 5 ($35), iPod touch ($25), and iPad mini ($40) in February, the hardshell polycarbonate case has a matte rubber finish. The iPad mini case also integrates with the Smart Cover. Kubxlab’s iPhone 5 ampjacket case comes in eight colors.
