The diaphragm is a carbon fiber and paper composite, and it is paired with a lightweight copper-plated aluminum voice coil. Grado's stated aim was definition and dynamic range in a presentation that stays natural rather than clinical.\u003c\/p\u003e\n\u003cp\u003eCarbon fiber and paper are a deliberate pairing. Paper is well damped and self-terminating; carbon fiber is stiff for its mass. A composite of the two is Grado's answer to holding diaphragm shape under load without the ringing a purely stiff material brings with it.\u003c\/p\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0555\/5073\/8528\/files\/grado-s750-inline-01.jpg\" alt=\"Grado Signature S750 open-back headphones, cups turned inward to show both B cushions and the red-sleeved cable\" style=\"width:100%;max-width:1000px;height:auto;border-radius:12px;margin:16px 0;\"\u003e\n\u003ch5\u003eThe Grado B Cushion, Explained\u003c\/h5\u003e\n\u003cp\u003eThe B cushion arrived with the S750 and is \u003ca href=\"\/collections\/grado-accessories\"\u003ethe newest shape in the Grado cushion range\u003c\/a\u003e. It does three things at once: it shortens the distance from driver to ear, it introduces a smaller interior opening that changes the acoustic balance, and eight precisely engineered slits let air move through it, which Grado credits for opening the soundstage while holding onto detail.\u003c\/p\u003e\n\u003cp\u003eThe flat surface is the comfort half of the argument. It distributes pressure more evenly across the ear than a domed pad, which is what Grado is aiming at for long sessions. In Richard Grado's words, the point is optionality: \u003cem\u003e\"The B cushion gives listeners another way to experience Grado headphones. We've always engineered our drivers to achieve the best sound possible, but we understand that every listener enjoys a slightly different sound signature.\"\u003c\/em\u003e\u003c\/p\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0555\/5073\/8528\/files\/grado-s750-inline-02.jpg\" alt=\"Grado Signature S750 open-back headphones, front view of both aluminum earcups\" style=\"width:100%;max-width:1000px;height:auto;border-radius:12px;margin:16px 0;\"\u003e\n\u003ch5\u003eAn All-Aluminum Housing at 460 Grams\u003c\/h5\u003e\n\u003cp\u003eThe S750 housing is aluminum throughout, each one handcrafted in Brooklyn. Aluminum is stiff and dense, which is what keeps the housing from adding its own signature to what the driver is doing, and Grado positions the metal-bodied models as the more analytical half of the Signature Line against the wood-bodied ones.\u003c\/p\u003e\n\u003cp\u003eWeight is where the S750 gains on the range above it. At 460 grams it is over ten percent lighter than the flagship while keeping the same build, and on an open-back headphone worn for hours that difference is felt rather than measured.\u003c\/p\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0555\/5073\/8528\/files\/grado-s750-inline-03.jpg\" alt=\"Grado Signature S750 open-back headphones, three-quarter view with the padded leather headband\" style=\"width:100%;max-width:1000px;height:auto;border-radius:12px;margin:16px 0;\"\u003e\n\u003ch5\u003eThe Detachable Cable System\u003c\/h5\u003e\n\u003cp\u003eThe S750 ships with a six-foot Signature Gold cable terminated in a 6.3mm single-ended plug. The braided construction is softer, more durable and lighter than Grado's older designs, and the improved insulation makes it noticeably more flexible in the hand.\u003c\/p\u003e\n\u003cp\u003eEach cup connects through a four-pin balanced mini XLR, the shared Signature Line connector. Cable length and source termination are therefore later decisions rather than purchase-time ones: Grado builds 4.4mm balanced, four-pin XLR balanced and longer runs against the same socket.\u003c\/p\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0555\/5073\/8528\/files\/grado-s750-inline-04.jpg\" alt=\"Grado Signature S750 open-back headphones, angled on a headphone stand\" style=\"width:100%;max-width:1000px;height:auto;border-radius:12px;margin:16px 0;\"\u003e\n\u003ch5\u003eThe Headband Assembly\u003c\/h5\u003e\n\u003cp\u003eThe S750 uses the same headband platform as the rest of the Signature Line, in a slightly narrower leather strap.
