Rather than pursuing an entirely new driver architecture, Grado focused on optimizing the interaction between the S2 driver and the acoustic properties of the housing.\u003c\/p\u003e\n\u003cp\u003eThis approach yields a presentation that is warmer and more forgiving, yet remains fast, detailed, and spatially open. The S550 offers a wide soundstage with precise imaging and natural dynamics, inviting longer listening sessions, while maintaining the immediacy and engagement Grado listeners expect.\u003c\/p\u003e\n\u003ch2\u003eBrazilian Walnut Housing\u003c\/h2\u003e\n\u003cp\u003eThe Signature S550 features housings crafted entirely from Brazilian Walnut, continuing Grado’s long-standing use of wood as an acoustic material. Each housing is individually made, with natural variations in grain ensuring that no two pairs are exactly alike.\u003c\/p\u003e\n\u003cp\u003eWalnut is valued for both its tonal characteristics and structural stability. Its density contributes to the S550’s fuller, more balanced presentation, while helping maintain consistent acoustical performance over time.\u003c\/p\u003e\n\u003cp\u003eThe wood is sourced with consideration for sustainable practices, supporting long-term availability while respecting the ecosystems in which it grows.\u003c\/p\u003e\n\u003ch2\u003eDetachable Cable System\u003c\/h2\u003e\n\u003cp\u003eThe Signature S550 ships standard with Grado’s Silver detachable cable, designed to be lighter, softer, and more flexible than previous Grado cables. Each housing is terminated with a 4-pin balanced mini XLR, allowing compatibility with Grado’s expanding ecosystem of detachable cables.\u003c\/p\u003e\n\u003cp\u003eThe included cable is terminated with a 3.5mm mini plug at the source end and includes a 6.3mm adapter, ensuring immediate compatibility with a wide range of audio equipment.\u003c\/p\u003e\n\u003cp\u003eAdditional cable options—featuring alternative lengths and balanced terminations—are available from Grado as aftermarket accessories or as part of the original purchase.\u003c\/p\u003e\n\u003ch2\u003eComfort, Fit and Personalisation\u003c\/h2\u003e\n\u003cp\u003eThe Signature S550 comes standard with Grado’s new B cushions and remains compatible with the full Grado cushion lineup, allowing listeners to tailor both comfort and sonic presentation to their individual preference.\u003c\/p\u003e\n\u003cp\u003eLike all headphones in the Signature Line, the S550 utilizes Grado’s Signature headband assembly. Integrated within the leather headband is a flexible metal support that allows the fit to be gently adjusted, enabling listeners to fine-tune how the headphone rests on the head and personalise comfort over time based on individual listening habits.\u003c\/p\u003e\n\u003cp\u003eThe S550 features the narrower leather headband strap, as used on the S750, and incorporates engraved metal gimbals, stainless-steel height rods, reinforced junction blocks, and controlled housing rotation to ensure durability, stability, and long-term comfort during extended listening sessions.\u003c\/p\u003e\n\u003cp\u003eSpecification : \u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTransducer Type:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eDynamic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Principle:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eOpen Air\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency Response:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e6 Hz – 44 kHz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTHD:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e\u0026lt;0.2% @100 dB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSPL 1mW:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e112 dB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Impedance:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e38 ohms\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDriver Size:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e50 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDriver Matching:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e0.05 dB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e335g (without cable)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCable Type:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eSignature Silver detachable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeadphone Connection:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e4-pin Mini XLR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSource Connection:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e3.5 mm w\/6.3 mm adapter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEarpad Supplied:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eB Cushion\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eIn the Box : \u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eHeadphones\u003c\/li\u003e\n\u003cli\u003e6 foot 6.3 mm terminated headphone cable\u003c\/li\u003e\n\u003cli\u003e6.3 mm headphone jack adapter\u003c\/li\u003e\n\u003cli\u003eWarranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Grado","offers":[{"title":"Default Title","offer_id":57377001832821,"sku":null,"price":19687.0,"currency_code":"MXN","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2222\/0805\/files\/grado_signature_series_s550_openback_headphones_without_cable.jpg?v=1784725756","url":"https:\/\/www.kronosav.com\/en-mx\/products\/grado-signature-s550-headphones","provider":"Kronos AV","version":"1.0","type":"link"}
