I recall this article from back in 2013: https://www.technologyreview.com/s/512496/first-graphene-audio-speaker-easily-outperforms-traditional-designs/ Highlight: To me this is incredible. How much better would this technology be when actually paired with specialised acoustic design. It's 2017 now. So where the heck are all the graphene headphones?! Even my tennis racquet claims to have graphene. Did all this turn out to be baloney?
