{"product_id":"gradosr225x","title":"Grado Prestige SR225x Open-Back Headphones","description":"\u003cp\u003eThe Grado Prestige SR225x is an open-back on-ear headphone with a 44mm X driver, and the first model in the series to feature the larger F-cushions and tightly matched driver pairs.\u003c\/p\u003e\n\u003cp\u003eThis is where the Prestige x series makes its biggest leap – not on the spec sheet, but on the soundstage.\u003c\/p\u003e\n\u003ch2\u003eWhy the SR225x?\u003c\/h2\u003e\n\u003cp\u003eTwo things change compared with the SR125x: Grado matches the drivers to within 0.05 dB instead of 0.1 dB, and the F-cushions move the diaphragm further from the ear. One sharpens the midrange imaging, the other opens up the space. Add to that the 8-conductor super-annealed copper cable and a frequency response reaching up to 22 kHz.\u003c\/p\u003e\n\u003ch2\u003eWhat you hear\u003c\/h2\u003e\n\u003cp\u003eNoticeably more air around the instruments than with the S-cushion models, plus a treble that extends rather than pushes. Vocals sit cleanly in the centre, cymbals decay finely. Anyone who knows the smaller Grados will hear the difference within the first ten seconds.\u003c\/p\u003e\n\u003ch3\u003eWho is the SR225x for?\u003c\/h3\u003e\n\u003cp\u003eFor anyone who likes the Grado sound but wants more space than the flat cushions allow – jazz, classical, well-recorded rock. Straight talk: the F-cushions sit on the ear, not around it. If you have sensitive ears, it's worth knowing beforehand. And it isolates nothing anyway.\u003c\/p\u003e\n\u003ch2\u003eOur verdict\u003c\/h2\u003e\n\u003cp\u003eFor us, the SR225x is the point where the Prestige series shows its full character: open, fast, honest. Stepping up to the SR325x brings aluminium and body – but the big sonic leap happens right here.\u003c\/p\u003e\n\u003ch2\u003eTechnical data\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eType: Open-back on-ear headphone (Open-Back, dynamic)\u003c\/li\u003e\n\u003cli\u003eSeries: Grado Prestige x\u003c\/li\u003e\n\u003cli\u003eDriver: 44 mm, Grado X driver\u003c\/li\u003e\n\u003cli\u003eFrequency response: 20–22,000 Hz\u003c\/li\u003e\n\u003cli\u003eSound pressure (1 mW): 98 dB\u003c\/li\u003e\n\u003cli\u003eNominal impedance: 38 Ω\u003c\/li\u003e\n\u003cli\u003eDriver channel matching: 0.05 dB\u003c\/li\u003e\n\u003cli\u003eEar cushions: F-cushion (large)\u003c\/li\u003e\n\u003cli\u003eCable: 8-conductor, super-annealed copper, permanently attached\u003c\/li\u003e\n\u003cli\u003eHousing: Polycarbonate\u003c\/li\u003e\n\u003cli\u003eHeadband: Vinyl\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\u003eWhat's included: Headphones, 6.3 mm jack adapter\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\n\u003ch3\u003eWhat do the F-cushions offer over the S-cushions?\u003c\/h3\u003e\n\u003cp\u003eDistance. The F-cushions hold the driver further from the ear, which makes the SR225x sound more open, more spacious and less direct than the SR60x, SR80x and SR125x with their flat S-cushions. The core character stays the same, but the soundstage grows noticeably – the most audible difference within the series.\u003c\/p\u003e\n\u003ch3\u003eWhat does the 0.05 dB channel matching mean?\u003c\/h3\u003e\n\u003cp\u003eGrado measures every driver and only pairs those that deviate by no more than 0.05 dB from each other – half the tolerance of the SR60x through SR125x. In practice that means a more stable centre image and more precise localisation. The same figure applies to the SR325x.\u003c\/p\u003e\n\u003ch3\u003eIs a headphone amplifier worth it for the SR225x?\u003c\/h3\u003e\n\u003cp\u003eRecommended, not required. At 38 Ω and 98 dB at 1 mW, it plays happily from a laptop too. But because it delivers noticeably more resolution than the smaller models, it's also the first to show what a clean headphone output adds in terms of calm and control.\u003c\/p\u003e\n\u003ch3\u003eWhy buy the Grado SR225x from HD Zürisee?\u003c\/h3\u003e\n\u003cp\u003eBecause we'll tell you honestly whether you really need to spend more on the SR325x – for many people, the answer is no.
