Science: Graphene headphones can beat your fancy cans
Feeling smug about those brand-name cans you just bought? A pair of researchers from Berkeley just made 'em obsolete with some Graphene. Conventional gear needs an oscillator that has to be damped down to produce a constant sound between 20Hz and 20kHz. Graphene, on the other hand, can be tailored to do the same job without any complicated, and power draining, over-engineering. Qin Zhou and Alex Zettl found their power-sipping setup to be as good, if not better than the pair of Sennheisers they tested it against. We're hopeful that Graphene headphones aren't too far away, assuming Fiddy doesn't get to the pair first and shut 'em down.
