{"product_id":"gradors1x","title":"Grado Reference RS1x Open-Back Headphones","description":"\u003cp\u003eThe Grado Reference RS1x is an open-back over-ear headphone that puts Grado's fourth-generation 50mm X-driver into a housing made of three different woods.\u003c\/p\u003e\n\u003cp\u003eMaple sleeve, hemp core, cocobolo outer ring: Grado calls it Tri-Wood, and each of the three woods has its own job in the housing. Everything is assembled by hand in Brooklyn – where the Grado family has been building headphones for four generations.\u003c\/p\u003e\n\u003ch2\u003eWhy the RS1x?\u003c\/h2\u003e\n\u003cp\u003eThe RS1x carries the large 50mm X-driver: stronger magnetic drive, lighter voice coil, newly tuned diaphragm, matched to 0.05 dB. It's specifically tuned for the Tri-Wood housing. Wood dampens resonances differently than plastic or metal – that's exactly where the warmth Grado's Reference series is known for comes from.\u003c\/p\u003e\n\u003ch2\u003eWhat you hear\u003c\/h2\u003e\n\u003cp\u003eA rich, lively midrange, clear vocals, refined treble and an open, cleanly layered soundstage. The bass reaches down to 12 Hz, staying dry rather than bloated. On the large L-cushions, the RS1x still sits comfortably after the third side of a record.\u003c\/p\u003e\n\u003ch3\u003eWho is the RS1x for?\u003c\/h3\u003e\n\u003cp\u003eFor anyone who wants Grado's mature wood sound at the top of the Reference series – at home, in peace and quiet, with music that deserves attention. Straight talk: open-back design means open in both directions. In an open-plan office or on the train, the RS1x makes nobody happy, least of all you.\u003c\/p\u003e\n\u003ch2\u003eOur verdict\u003c\/h2\u003e\n\u003cp\u003eThree woods, the big driver, handwork: the RS1x is Grado's wood craftsmanship at its best. A headphone for connoisseurs seeking the warm Grado sound in its purest Reference form. Hand on heart – once you've heard wood, you rarely reach for a plastic housing again.\u003c\/p\u003e\n\u003ch2\u003eTechnical Data\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eType: Open-back over-ear headphones (open-back, dynamic)\u003c\/li\u003e\n\u003cli\u003eSeries: Grado Reference (flagship)\u003c\/li\u003e\n\u003cli\u003eOperating principle: Open air\u003c\/li\u003e\n\u003cli\u003eDriver: 50 mm, Grado X-driver (4th generation)\u003c\/li\u003e\n\u003cli\u003eDriver matching: 0.05 dB\u003c\/li\u003e\n\u003cli\u003eHousing: Tri-Wood – maple sleeve, hemp core, cocobolo outer ring\u003c\/li\u003e\n\u003cli\u003eFrequency response: 12–30,000 Hz\u003c\/li\u003e\n\u003cli\u003eSound pressure (1 mW): 99.8 dB\u003c\/li\u003e\n\u003cli\u003eNominal impedance: 38 Ω\u003c\/li\u003e\n\u003cli\u003eCushions: L-cushion\u003c\/li\u003e\n\u003cli\u003eCable: 8-conductor, super-annealed copper, fixed\u003c\/li\u003e\n\u003cli\u003eHeadband: Leather with white stitching\u003c\/li\u003e\n\u003cli\u003eConnector: 3.5 mm jack, 6.3 mm adapter included\u003c\/li\u003e\n\u003cli\u003eManufacturing: Hand-assembled in Brooklyn, NY\u003c\/li\u003e\n\u003cli\u003eIncluded: Headphones, 6.3 mm jack adapter\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3\u003eWhat's the difference between the Grado RS1x and the RS2x?\u003c\/h3\u003e\n\u003cp\u003eThe RS1x has the larger 50mm X-driver and a Tri-Wood housing made of maple, hemp and cocobolo; its frequency response spans 12 to 30,000 Hz. The RS2x runs a 44mm driver, maple and hemp, and 14 to 28,000 Hz. The RS1x sits a step above.\u003c\/p\u003e\n\u003ch3\u003eDoes the Grado RS1x need a headphone amp?\u003c\/h3\u003e\n\u003cp\u003eNot strictly. At 38 Ω and 99.8 dB per milliwatt, the RS1x already plays well from a good dongle DAC or the headphone output of an integrated amp. A dedicated headphone amp, though, audibly adds calm, dynamics and control, especially with dense music.\u003c\/p\u003e\n\u003ch3\u003eCan I swap the cushions on the Grado RS1x?\u003c\/h3\u003e\n\u003cp\u003eYes. The RS1x comes with the large L-cushions, which pull off and can be replaced. Grado sells the cushions individually, and many listeners also try other Grado cushions – each changes the fit and tonal balance somewhat. Replacements are in our headphone accessories.\u003c\/p\u003e\n\u003ch3\u003eWhy buy the Grado RS1x from HD Zürisee?\u003c\/h3\u003e\n\u003cp\u003eBecause the people advising you here have had Grado on the shelf for years.
