{"product_id":"grado-hemp-classic-series-open-back-headphones","title":"Grado Hemp Classic Series Open-Back Headphones","description":"\u003cp\u003eThe Grado Hemp is the first wood-cup model in the Classic Series, and the wood is the point. Its housing pairs hempwood with maple: hempwood for damping and tonal warmth, maple for structural stability at the driver-to-shell junction. Inside sits the 44mm X2 driver, tuned here for a fuller and more grounded presentation, on F cushions and an eight-conductor cable.\u003c\/p\u003e\n\n\u003ch5\u003eKey Features of the Grado Hemp\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003e44mm X2 Dynamic Driver:\u003c\/b\u003e Mylar diaphragm, copper voice coil and a rare earth magnet system, tuned on this model for a fuller and more grounded presentation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eHempwood and Maple Housing:\u003c\/b\u003e A bi-wood shell.

Hempwood is the damping half: Grado credits it with natural damping and tonal warmth, and describes the presentation it shapes as grounded and physical. Maple is the stiff half, and Grado uses it at the driver interface for structural stability.\u003c\/p\u003e\n\u003cp\u003eHempwood is also the more interesting material commercially. Hemp fibers can be cultivated and replenished far more rapidly than traditional hardwoods, which is Grado's stated reason for reaching for it. The fibrous grain is visible on the face of every cup, and because the material is worked individually, no two pairs look the same.\u003c\/p\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0555\/5073\/8528\/files\/grado-hemp-inline-01.jpg\" alt=\"Grado Hemp open-back headphones, close-up of one earcup showing the marbled hempwood grain, the mesh grille and the Grado Hemp medallion\" style=\"width:100%;max-width:1000px;height:auto;border-radius:12px;margin:16px 0;\"\u003e\n\u003ch5\u003eThe 44mm X2 Driver, Tuned for Weight\u003c\/h5\u003e\n\u003cp\u003eThe Hemp runs Grado's 44mm X2 dynamic driver: a Mylar diaphragm, a copper voice coil and a rare earth magnet system. It is the same diaphragm size the SR60, SR80 and SR325 use, so the step from those models to this one is about the housing and the cushion, not about driver area.\u003c\/p\u003e\n\u003cp\u003eGrado's voicing here is different from the models below it. Where the SR325 is tuned for articulation and speed, the Hemp is tuned to favor a fuller and more grounded presentation. Each Classic Series model is tuned in relation to its own housing rather than to one house curve, and the wood is what this one is tuned around.\u003c\/p\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0555\/5073\/8528\/files\/grado-hemp-inline-02.jpg\" alt=\"Grado Hemp open-back headphones, front view of both hempwood and maple earcups\" style=\"width:100%;max-width:1000px;height:auto;border-radius:12px;margin:16px 0;\"\u003e\n\u003ch5\u003eF Cushions and What They Do\u003c\/h5\u003e\n\u003cp\u003eThe Hemp ships on Grado F cushions, which bring the driver close to the ear and reinforce the immediate, engaging character the model is voiced for. It is the same cushion the SR80 and SR325 use, so it is the constant across three different housings in the range.\u003c\/p\u003e\n\u003cp\u003eIt is also adjustable. \u003ca href=\"\/collections\/grado-accessories\"\u003eGrado sells S, F, L, B and G cushions separately\u003c\/a\u003e and treats the pad as a tuning element: a larger cushion sets the driver farther from the ear and opens up width, a smaller one brings it closer and pushes the midrange forward. On a Grado the cushion is a choice you make rather than a part that simply wears out.\u003c\/p\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0555\/5073\/8528\/files\/grado-hemp-inline-03.jpg\" alt=\"Grado Hemp open-back headphones, cups turned to show both F cushions with the drivers visible through the opening\" style=\"width:100%;max-width:1000px;height:auto;border-radius:12px;margin:16px 0;\"\u003e\n\u003ch5\u003eThe Signature Silver Headband and Eight-Conductor Cable\u003c\/h5\u003e\n\u003cp\u003eThe Hemp carries Grado's Signature Silver headband assembly, which shares its engineering foundation with the Signature Gold system used higher in the Classic Series but is lighter. A padded leather headstrap with contrasting white stitching sits against the head, over an internal steel spring band.\u003c\/p\u003e\n\u003cp\u003eClamping pressure is set by bending that band by hand rather than by a click-stop mechanism, so the fit is dialed in once and stays. The cable is an eight-conductor Signature Silver design terminated in a 3.5mm mini plug, with a quarter-inch adapter supplied, and it is hard-wired into the cups. Detachable cables are a Signature Line feature and are not offered anywhere in the Classic Series.\u003c\/p\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0555\/5073\/8528\/files\/grado-hemp-inline-04.jpg\" alt=\"Grado Hemp open-back headphones, three-quarter view with the left cup rotated to expose the F cushion and the driver behind it\" style=\"width:100%;max-width:1000px;height:auto;border-radius:12px;margin:16px 0;\"\u003e\n\u003ch5\u003eWhat the Classic Series Means\u003c\/h5\u003e\n\u003cp\u003eThe Classic Series is Grado's name for seven of its most recognizable headphones brought together on the X2 driver platform, with updated cable assemblies and refined build components.
