http://www.blogcdn.com/www.engadget.com/media/2013/03/sharifgraphene.jpg Feeling smug about those brand-name cans you just bought? A pair of researchers from Berkeleyjust 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](http://www.engadget.com/2012/08/31/50-cent-sms-audio-headphones/) doesn’t get to the pair first and shut 'em down.
