This isn’t your father’s Walkman. As if there weren’t already enough iPhone speakers and cases on the market. Still, the iMainGo X ($69.95) achieves the combination of these overkilled accesories wonderfully. The case houses iPhones, iPods and most other small mp3 players and features an extra large 37mm premium high output stereo to give your sound a little more boom. Available in black and pink and can be used as an external speaker for any device with a 3.5 mm connection (basically anything with a headphone jack). And if “pretty damn loud” doesn’t cut it for you, the ability to daisy chain (connect multiple iMainGo X’s) can make your sound double, triple, quadruple, quintuple, etc.
