We all know that the iPhone and iPod touch have pretty skimpy speakers. iPods have no speakers, so we're dependent on headphones or speakers to get any tunes out of them.
Portable Sound Laboratories has an interesting solution that will protect your electronics and give you good sound at the same time. It's called the iMainGo2, and it's a 9 oz., clamshell zippered case that will hold an iPhone or an iPod touch. There's a headphone compatible 3.5mm plug that connects the case to your device. The unit runs on 4 AAA batteries for about 30 hours. We have one on loan for review, and I've been testing it around the house for a few days.
How does it sound? Better than I expected. It had nice bright highs, which were especially audible on percussion like snare drums and triangles. The bass is good, but this is not a device to equal a much bigger speaker system with a subwoofer. Still, it's more than reasonable. The unit appears to use a bass reflex or ducted port design, and if you close your eyes and just listen, you would think you were listening to a bigger system.
