Three different wood species are working together in a Grado RS1x headphone. The housing is made of a maple sleeve, hemp core, and cocobolo outer ring. Grado is constructed with wood for its warm and embracing tonal abilities, but finding the right balance of three separate woods is no simple task. The reward though is an grado RS1x that opens Grado to a new level of sound.
