In Grado’s never-ending pursuit to experiment with all types of woods and materials, they had the opportunity to build with hemp and believe it or not, are one of the best sounding Limited Editions they ever built.

The highly compressed hemp creates a damping effect between their fibers. This produces a fuller sound, comprised of a noticeable low end and a top end that extends smoothly to its limits. The hemp may be doing the heavy lifting, but the hemphone is a joint effort. We built maple into the housing to help balance out the sound, and bring out the sonic properties that we’ve heard maple produce.
