That's the more honest approach: wood sounds different from aluminium, so it needs to be voiced differently too. Add to that the new B cushions, a detachable Signature Silver cable and 4-pin mini-XLR connectors on both earcups – features that were reserved for the flagship models not long ago.\u003c\/p\u003e\n\u003ch2\u003eWhat you hear\u003c\/h2\u003e\n\u003cp\u003eWarmth, without losing pace. The S550 is the most relaxed take on the Grado sound: rounded treble, full mids, a wide stage – and still that typical directness. Driver matching of 0.05 dB keeps that stage standing clean. Every housing is made individually, so no two grain patterns are ever quite the same.\u003c\/p\u003e\n\u003ch3\u003eWho is the S550 for?\u003c\/h3\u003e\n\u003cp\u003eFor long evenings with music rather than short analytical sessions – and for anyone who finds 460 grams on their head too much. Honestly: if you're after headphones for commuting, the office, or a home office you share with others, look elsewhere – the open design doesn't seal in anything. And if you want maximum precision, the S750 or the HP100 SE are the better call.\u003c\/p\u003e\n\u003ch2\u003eOur verdict\u003c\/h2\u003e\n\u003cp\u003eThe S550 is the friendliest way into Grado's Signature line: the same S2 driver as the S750, noticeably lighter, tuned warmer – and at 335 grams, one of the most comfortable Grados around.\u003c\/p\u003e\n\u003ch2\u003eTechnical specs\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eType: Open-back over-ear headphones (open air, dynamic)\u003c\/li\u003e\n\u003cli\u003eSeries: Grado Signature\u003c\/li\u003e\n\u003cli\u003eDriver: 50 mm S2, tuned to the solid-wood housing\u003c\/li\u003e\n\u003cli\u003eFrequency response: 6 Hz – 44 kHz\u003c\/li\u003e\n\u003cli\u003eTotal harmonic distortion: \u0026lt; 0.2% at 100 dB\u003c\/li\u003e\n\u003cli\u003eSensitivity: 112 dB (1 mW)\u003c\/li\u003e\n\u003cli\u003eImpedance: 38 ohms\u003c\/li\u003e\n\u003cli\u003eDriver matching: 0.05 dB\u003c\/li\u003e\n\u003cli\u003eHousing: Solid Brazilian walnut, handmade in Brooklyn\u003c\/li\u003e\n\u003cli\u003eEar cushions: B cushions (fitted), compatible with S, F, L and G cushions\u003c\/li\u003e\n\u003cli\u003eCable: Signature Silver, detachable, 1.8 m (6 ft)\u003c\/li\u003e\n\u003cli\u003eEarcup connector: 4-pin mini-XLR (balanced)\u003c\/li\u003e\n\u003cli\u003eSource connector: 3.5 mm jack with 6.3 mm adapter\u003c\/li\u003e\n\u003cli\u003eWeight: 335 g (without cable)\u003c\/li\u003e\n\u003cli\u003eWhat's in the box: headphones with B cushions, detachable Signature Silver cable, 6.3 mm adapter\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\n\u003ch3\u003eWhat's the difference between the S550 and the S750?\u003c\/h3\u003e\n\u003cp\u003eBoth use the 50 mm S2 driver. The S550 sits in Brazilian walnut and sounds warmer, rounder and more relaxed; the S750 in its aluminium housing plays tighter and more direct. At 335 g, the S550 is noticeably lighter and connects via a 3.5 mm jack, while the S750 uses 6.3 mm.\u003c\/p\u003e\n\u003ch3\u003eCan I use other Grado cushions with the S550?\u003c\/h3\u003e\n\u003cp\u003eYes. It ships with the new B cushions as standard, but S, F, L and G cushions are also compatible. Each variant noticeably changes fit and sound: smaller cushions sit closer to the ear and sound more direct, larger ones open up the soundstage.
