HEADPHONES: Berkeley creates the first graphene earphones, and (unsurprisingly) they’re awesome says Sebastian Anthony

Berkeley's graphene earphone

Researchers at the University of California, Berkeley have created the first ever graphene audio speaker: an earphone. In its raw state, without any kind of optimization, the researchers show that graphene’s superior physical and electrical properties allow for an earphone with frequency response comparable to or better than a pair of commercial Sennheiser earphones.
