Simon Lyall Posted March 14, 2013 Share Posted March 14, 2013 Just saw this article and thought it might prove interesting reading about potential future technology: http://www.extremetech.com/electronics/150646-berkeley-creates-the-first-graphene-earphones-and-unsurprisingly-theyre-awesome Simon Link to comment Share on other sites More sharing options...

paulears Posted March 14, 2013 Share Posted March 14, 2013 The lack of accurate data does colour it though, doesn't it - a frequency response curve without labels and scales is a bit pointless. If you assume the Sennheiser curve used for comparison is in reality not that curvy they've expanded the vertical scale to make it more 'exciting'. I've not seen a Sennheiser plot looking like that. If you decrease vertical scale, then the new product has nothing very special in performance, apart from more bass? Lots of hyperbole, little substance.

Simon Lyall Posted March 14, 2013 Author Share Posted March 14, 2013 Paul I think you banged the nail on the head there as usual, although I'll keep an ear to the ground to see if a proper peer reviewed paper comes out of this research. Would be interesting to see the quantifiable data. Simon Link to comment Share on other sites More sharing options...
bigclive Posted March 14, 2013 Share Posted March 14, 2013 The thing is... It's super low mass. No coil to compensate for, and the electrostatic movement has theoretically got near DC resolution. I could see this having a fairly flat response without too much acoustic tuning. Link to comment Share on other sites More sharing options...
paulears Posted March 14, 2013 Share Posted March 14, 2013 The only thing I wondered about was the inclusion of the non-conductive layer to prevent it bottoming out. The Quad speakers sounded great, but couldn't manage too much diaphragm movement without shorting - the coating would stop the headphones electrically shorting, but I wonder what it sounds like?
