Sennheiser showed off the new Orpheus headphones on November 10, 2015 in New York and Bloomberg Pursuits' Stephen Pulvirent got a first look. There are over 6,000 individual components, including everything from the tiniest transistors to the all-natural white Carrera marble housing in each pair. (You've read that correctly.) Materials such as gold and platinum-plated ceramic are used throughout for maximum conductivity and performance, but all those bells and whistles don't come cheap. The Orpheus will set you back $50,000.
