Recycled paper is quickly becoming a favored material for portable, lightweight speaker solutions. First we had Eco-Amp, now we have Pulpop, an O-shaped speaker system made from post-consumer pulp. The device was created by Taiwanese designers Balance Wu and Chin Yang, who surprised themselves with Pulpop's "unexpectedly potent" sound quality. The recycled paper pulp system works with a standard double-ended headphone cable and is rechargeable through a USB port.
