Since developing ways to acquire graphene — a one-atom thick sheet of carbon — in significant quantities, research around the material has become the next big thing, and scientists at Berkeley have now detailed a new application for the material: earphones. “Graphene is an ideal building material for small, efficient, high-quality broad-band audio speakers,” researchers Qin Zhou and A. Zettl write in their report. The team compares graphene to Sennheiser’s MX-400 earbuds, and notes that the material performs comparably even without a specialized design.
