Limited Edition Reference Series Hemp / Maple Headphones, by Grado Labs.

The first of its kind, hemp finds yet another purpose in The Hemp Headphone. A brilliant, warm, and precise sound rolled into this limited edition Grado.

In their never-ending pursuit to experiment with all types of woods and materials, Grado had the opportunity to build with hemp. To everyone’s surprise they quickly became a favourite passed around Grado labs. To be blunt, this is one of the best sounding Limited Editions they have ever built.

The highly compressed hemp creates a damping effect between the fibres. 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. Maple has been built into the housing to help balance out the sound, and bring out the sonic properties that maple can produce.

The Grado drivers built into the hemp housings had to be specifically tuned for a material never worked with before. Being paired with maple gave some foresight, but only through trial-and-error could Grado get the speakers to sound how they wanted, and bring out the potential of the hemp.

The last seven decades has given Grado time to perfect their sound, letting the headphones reveal new notes and details in songs heard hundreds of times. The Hemp Headphone is a slow burn, constantly getting better with every listen. As they make sure with every headphone built, the Grado signature sound is ever-present, working in tandem with the hemp and maple.

Each Hemp Headphone is hand-built by the Grado team in Brooklyn. Fine rolled for every genre of music, hemp and maple work together for the first time to bring a new level of vibrancy to the Limited Editions.
