A Pocket Full of Sound

IDEA International MP3 Card Speaker

 While it won&#39;t deliver the thumping bass of a trunk full of subwoofers, this ultraminimal card speaker packs serious punch for its portable dimensions and brings some clarity and kick to otherwise feeble-sounding electronics. (That&#39;s right, iPad. We&#39;re looking at you.) The all-metal chassis, about the same size as a stack of credit cards, is rugged, refined, and timeless—the perfect companion to gadgets that have yet to be invented.
