{"product_id":"grado-classic-rs1-open-back-kopfhoerer","title":"Grado Classic RS1 Open-Back Headphones","description":"\u003cp\u003eThe Grado Classic RS1 is an open-back over-ear headphone with a 50mm X2 driver in a three-layer wood housing of maple, hemp, and cocobolo.\u003c\/p\u003e\n\u003cp\u003eIt's the compact climber of the Classic series – where Grado tradition meets modern build quality without the housing taking on the size of a GS model. Don't confuse it: the Classic RS1 without an \"x\" is a different model from the Reference RS1x of the older x series.\u003c\/p\u003e\n\u003ch2\u003eWhy the RS1?\u003c\/h2\u003e\n\u003cp\u003eThree woods, three jobs: maple for clarity, hemp for damping, cocobolo for density and depth. This Tri-Wood construction is the real trick behind the RS1. Add to that the 50mm X2 driver, the Signature Gold headband with engraved aluminum-alloy gimbals, and the lighter Signature Silver cable – good mechanics you'll still appreciate years later.\u003c\/p\u003e\n\u003ch2\u003eWhat you hear\u003c\/h2\u003e\n\u003cp\u003eMids that look you right in the eye. The RS1 is more focused than the GS models: voices and guitars sit closer, transients arrive faster, the space is more tightly framed. The L-cushions sit on the ear and deliberately keep the presentation compact.\u003c\/p\u003e\n\u003ch3\u003eWho is the RS1 for?\u003c\/h3\u003e\n\u003cp\u003eFor anyone who prefers listening intensely rather than expansively – rock, singer-songwriter, jazz trio. Honestly: if you want a big orchestral soundstage, reach for the Classic GS1000 instead. And if you have sensitive ears, take a close look at the L-cushions; on-ear isn't for everyone.\u003c\/p\u003e\n\u003ch2\u003eOur verdict\u003c\/h2\u003e\n\u003cp\u003eThe RS1 is the Grado for people who want to get closer. Compact, fast, with a wood housing that looks like craftsmanship rather than an effect – and in the Classic series, the best compromise between character and everyday usability.\u003c\/p\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eType: Open-back over-ear headphones (open air, dynamic)\u003c\/li\u003e\n\u003cli\u003eSeries: Grado Classic\u003c\/li\u003e\n\u003cli\u003eDriver: 50mm X2 with Mylar diaphragm, copper voice coil, and rare-earth magnet system\u003c\/li\u003e\n\u003cli\u003eFrequency response: 12 – 30,000 Hz\u003c\/li\u003e\n\u003cli\u003eSensitivity (1 mW): 99.8 dB\u003c\/li\u003e\n\u003cli\u003eNominal impedance: 38 ohms\u003c\/li\u003e\n\u003cli\u003eDriver matching: 0.05 dB\u003c\/li\u003e\n\u003cli\u003eHousing: Tri-Wood of maple, hemp, and cocobolo, handcrafted in Brooklyn\u003c\/li\u003e\n\u003cli\u003eEar cushions: L-cushion\u003c\/li\u003e\n\u003cli\u003eHeadband: Signature Gold, engraved aluminum-alloy gimbals, stainless-steel height rods, genuine leather headband\u003c\/li\u003e\n\u003cli\u003eCable: Signature Silver, permanently attached; XLR termination optional\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3\u003eWhat's the difference between the Classic RS1 and the Reference RS1x?\u003c\/h3\u003e\n\u003cp\u003eTwo models from two lines. The RS1x belonged to the Reference x series; the Classic RS1 arrived at the end of March 2026 with the Classic series: reworked X2 driver platform, lighter Signature Silver cable, reworked headband. The Tri-Wood housing of maple, hemp, and cocobolo remains the shared hallmark.\u003c\/p\u003e\n\u003ch3\u003eWhat does Tri-Wood mean on the RS1?\u003c\/h3\u003e\n\u003cp\u003eThe housing is made of three different woods instead of one: maple, hemp, and cocobolo. Each material dampens and resonates differently, and the combination results in a fuller tonality than a single wood would. Side effect: every housing looks a little different thanks to the grain.\u003c\/p\u003e\n\u003ch3\u003eRS1 or GS1000 – which suits me better?\u003c\/h3\u003e\n\u003cp\u003eThe RS1 is more compact, more direct, and more mid-focused, with L-cushions on the ear. The GS1000 plays more spaciously and relaxed, with large G-cushions around the ear. In short: RS1 for closeness and energy, GS1000 for space and composure. Both share the 50mm X2 driver.\u003c\/p\u003e\n\u003ch3\u003eWhy buy the Grado Classic RS1 from HD Zürisee?\u003c\/h3\u003e\n\u003cp\u003eBecause cushion shape and fit are what decide between joy and frustration with Grado – and that's not on any spec sheet.
