There is a reason that most speakers aren't portable. The next time I have to listen to someone's horrible R&B tunes at the park I will probably choke someone out. But this gadget fulfills the need for people to annoy everyone else. These fold up almost completely flat for storage in an included plastic bag for easy carrying. Annoy everyone around you and look like a high-tech freak—two birds with one stone, honestly. These are available for $42 through the Museum of Modern Art store.
