There are 480 x 272 reasons to love the PSP. But the well-hidden speakers that can be drowned out by the sound of a liquid-cooled PC are not one of them. That's why it's always a pleasure to see someone rigging a set of boosters to the thing. These new PSP speakers by Princeton are nicely designed to fit in with your PSP's aesthetic (unless, of course, you held out for a white one), this 2.1 speaker set runs on 3 alkaline batteries to avoid sapping the PSP's charge. The MS-HHS measures 280 x 38 x 102mm and weighs about 430 grams. Currently selling for about 70 Euro, no word on pricing or availability elsewhere.
