Two to Tango
Our family of woods in the Heritage Series is growing with the Norwegian Pine used in the new GH3 and GH4. The GH4 is the successor to the GH1 and GH2, which used Brooklyn Maple and Cocobolo, respectively.
These limited editions are the first Grado headphones to utilize the warm and textured tonal abilities of Norwegian Pine. We sourced a specific species of this wood for the housings, searching for the right patterns and musical character desired for the GH4. This headphone has a unique voicing that can only be created by combining the full-sized body crafted from seasoned and treated Norwegian Pine with our signature drivers.
