High-end audio kit maker Grado Labs has revealed its latest headphones, and they’ve looked to an unusual material to do it: hemp. The new Grado Hemp Limited Edition takes a wood more commonly associated with, well, burning and instead takes advantage of its density characteristics for a more distinctive sound.

And here’s some more blurb….

Turns out, hemp wood – which is highly compressed – creates a damping effect between the fibers. The result, Grado, says, is a fuller sound: “a noticeable low end and a top end that extends smoothly to its limits,” the audio specialist claims.

It’s not all hemp, mind. Grado has also thrown in some maple, using it to balance out the sound by building it into the headphones’ housing. Everything is hand-built by the company’s team in Brooklyn, just like Grado’s other limited editions, with a matching padded leather headband.

The hemp doesn’t just sound good, it looks the part too. The distinctive striations of that and the maple help make the limited edition headphones stand out. As for technical specs, the dynamic transducer has a 12 Hz to 28 kHz frequency response, 38 ohms of normal impedance, and the drivers are .05 dB matched.
