Leaders of the Drivers For the first time, three different species of wood work together in Grado headphones. The shell is made with maple veneer, hemp core and cocobolo outer ring. Grado has chosen the wood for its quality and great tonal abilities, finding the perfect balance between the three woods, which has not been an easy task. The Grado RS1x are the first headphones to feature the large 50mm X drivers. This new transducer design features a more powerful magnetic circuit, a voice coil with reduced effective mass and a reconfigured diaphragm.
