I’ve heard about those graphene headphones! It’s a bummer that they didn’t hit their stretch goal for active noise cancellation.
Also, I’m curious about their decision to tune for a flat frequency response. While that might look good on paper, in a headphone a perfectly flat response won’t actually sound flat to the ear, due to the way acoustics work at that close range. Bet the speed will rival the best stuff from Beyerdynamic though!
