These are the world's first dynamic headphones with a Thin-Ply Carbon Diaphragm (TPCD). Developed with Sweden's Composite Sound, the headphones control diaphragm resonances through the stiffness and density of the composite structure. This removes the need for damping materials often used in similar dynamic headphones, allowing faster and more precise diaphragm movement.
