Its 44mm X2 driver is matched channel to channel within 0.05 dB, half the tolerance of the SR60 and SR80, and the metal housing damps resonance a thinner shell would pass straight back into the driver.\u003c\/p\u003e\n\n\u003ch5\u003eKey Features of the Grado SR325\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003e44mm X2 Dynamic Driver:\u003c\/b\u003e Mylar diaphragm, copper voice coil and a rare earth magnet system, tuned for articulation and speed.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003ePrecision-Machined Aluminum Housing:\u003c\/b\u003e Reduces unwanted resonance in a way molded plastic cannot, supporting a fast and controlled presentation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003e0.05 dB Driver Matching:\u003c\/b\u003e The tightest channel-to-channel matching in the Classic Series, half the tolerance Grado specifies for the SR60 and SR80.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eSignature Silver Headband Assembly:\u003c\/b\u003e Engraved reinforced polymer gimbals and junction blocks, taken from the same engineering platform as the Signature Gold system but lighter.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eGenuine Leather Headstrap:\u003c\/b\u003e Contrasting white stitching over an internal steel spring band you bend yourself to set clamping pressure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eSignature Silver Cable:\u003c\/b\u003e Reduced weight and improved flexibility compared with Grado's earlier cable designs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eF Cushions:\u003c\/b\u003e Hold the driver close to the ear and reinforce the immediate, energetic presentation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003e18Hz to 24kHz Response:\u003c\/b\u003e The widest quoted bandwidth of the three Classic Series models we stock.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eAssembled in Brooklyn, New York:\u003c\/b\u003e Built in the same building the Grado family has owned since 1918.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch5\u003eThe X2 Driver Behind the Classic Series\u003c\/h5\u003e\n\u003cp\u003eThe SR325 uses Grado's 44mm X2 dynamic driver, built from a Mylar diaphragm, a copper voice coil and a rare earth magnet system engineered for efficiency and control. Grado tunes this one for articulation and speed, which shows up as tight bass response, forward midrange clarity and crisp high-frequency extension. The X2 platform is shared across every Classic Series model, so the driver is not what separates the SR325 from the SR80.\u003c\/p\u003e\n\u003cp\u003eWhat does separate them is tolerance. Grado matches the SR325's two drivers to within 0.05 dB of each other, against 0.1 dB on the SR60 and SR80. Channel matching is what holds a center image steady: the closer the two drivers track, the less a voice drifts off center as the music changes level.\u003c\/p\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0555\/5073\/8528\/files\/sr325-inline-02.jpg?v=1788460736\" alt=\"Grado SR325 open-back headphones, front view with both driver grilles facing camera\" style=\"width:100%;max-width:1000px;height:auto;border-radius:12px;margin:16px 0;\"\u003e\n\u003ch5\u003eWhy the SR325 Uses an Aluminum Housing\u003c\/h5\u003e\n\u003cp\u003eThe SR325 is the only model of the three we stock with a precision-machined aluminum housing rather than the die-injection molded shell used on the SR60 and SR80. Aluminum is denser and stiffer, and Grado specifies it here to reduce unwanted resonance while supporting a fast and controlled presentation. A housing that rings adds its own signature to everything played through it.\u003c\/p\u003e\n\u003cp\u003eThe finish on this generation is black. Earlier SR325 models were sold in a silver finish, so a photograph of an older unit will not match what arrives.\u003c\/p\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0555\/5073\/8528\/files\/sr325-inline-05.jpg?v=1788460738\" alt=\"Grado SR325 open-back headphones, angled view showing the leather headband\" style=\"width:100%;max-width:1000px;height:auto;border-radius:12px;margin:16px 0;\"\u003e\n\u003ch5\u003eSignature Silver Headband and Cable\u003c\/h5\u003e\n\u003cp\u003eThe SR325 carries Grado's Signature Silver headband assembly, developed from the same engineering platform as the Signature Gold system used higher in the range. It uses engraved reinforced polymer gimbals and junction blocks that keep the Gold platform's improved geometry and controlled rotation while cutting weight, and a genuine leather headstrap with contrasting white stitching sits against the head.\u003c\/p\u003e\n\u003cp\u003eInside the strap is a steel spring band. Grado intends you to bend it: clamping pressure is adjusted by hand rather than by a click-stop mechanism, so the fit is set once to your head and stays there. The cable is Grado's Signature Silver design, lighter and more flexible than the cable it replaces, and hard-wired into the cups. Detachable cables are a Signature Line feature and are not offered anywhere in the Classic Series.\u003c\/p\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0555\/5073\/8528\/files\/sr325-inline-03.jpg?v=1788460736\" alt=\"Grado SR325 open-back headphones, cushion side with both F cushions facing camera\" style=\"width:100%;max-width:1000px;height:auto;border-radius:12px;margin:16px 0;\"\u003e\n\u003ch5\u003eF Cushions and How Grado Tunes With Them\u003c\/h5\u003e\n\u003cp\u003eThe SR325 ships with Grado F cushions, which hold the driver close to the ear and reinforce its immediate and energetic presentation. Grado treats cushions as a tuning element rather than a comfort part: changing the cushion changes the distance from driver to ear, and with it the tonal balance. Owners routinely swap between S, F, L and G cushions to shift the presentation, and Grado sells them separately for exactly that reason.\u003c\/p\u003e\n\u003cp\u003eThese are on-ear cups. They sit on the ear rather than enclosing it, which is central to the Grado design and is also the thing most worth trying before committing if you have not worn a pair before.\u003c\/p\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0555\/5073\/8528\/files\/sr325-inline-04.jpg?v=1788460737\" alt=\"Grado SR325 open-back headphones, one earcup showing the driver grille, one showing the F cushion\" style=\"width:100%;max-width:1000px;height:auto;border-radius:12px;margin:16px 0;\"\u003e\n\u003ch5\u003eWhat the Classic Series Changed\u003c\/h5\u003e\n\u003cp\u003eGrado introduced the Classic Series, bringing the SR325 together with the SR60, SR80, Hemp, RS1, GS1000 and GS3000 under one banner and moving them onto the X2 driver platform. Grado describes the goal as improved consistency, control and refinement, with greater clarity, extension and balance, while preserving the lively presentation the range is known for.\u003c\/p\u003e\n\u003cp\u003eTwo other things changed alongside the driver. The cable is a newly developed Signature design, built to be lighter, softer and more flexible while keeping Grado's traditional hard-wired construction. The headbands were reworked for comfort and long-term durability without changing the familiar look. Every Classic Series headphone continues to be assembled in Brooklyn.\u003c\/p\u003e\n\n\u003ch5\u003eGrado Labs, Three Generations In\u003c\/h5\u003e\n\u003cp\u003eGrado Labs has been a family-owned American company since 1953, founded by Audio Hall of Fame member Joseph Grado, who invented the moving coil stereo cartridge and developed the first true high-end dynamic headphone. The company still works out of the Brooklyn building that Pasquale Grado bought in 1918, which started life as the family fruit store.\u003c\/p\u003e\n\u003cp\u003eJohn Grado took over from his uncles in the early 1990s, having swept the floors of the same building as a boy in the 1960s. He handed leadership to his brother Richard in 2023, with Jonathan and Matthew Grado, the third generation, coming up behind them. The headphones and the cartridges are still made in that building.\u003c\/p\u003e\n\n\u003cstyle\u003e\n.tlr-cmp{margin:18px 0 6px;}\n.tlr-cmp .cmp-sub{color:#6b6b68;font-size:13.5px;margin:0 0 14px;}\n.tlr-cmp .cmp-row{border:1px solid #eee;border-radius:8px;padding:12px 14px;margin:8px 0;cursor:pointer;transition:border-color .2s ease;}\n.tlr-cmp .cmp-row:hover{border-color:#d9c6b3;}\n.tlr-cmp .cmp-cur{background:#f7f1ec;border:1px solid #ecdcca;border-left:3px solid #a3704d;}\n.tlr-cmp .cmp-cur:hover{border-left-color:#a3704d;}\n.tlr-cmp .cmp-name{font-weight:700;color:#2a2b2a;font-size:15px;}\n.tlr-cmp a{text-decoration:none!important;opacity:1!important;color:#2a2b2a;padding-bottom:2px;\n  background-image:linear-gradient(#a3704d,#a3704d),linear-gradient(#cbb9a6,#cbb9a6);\n  background-position:left 100%,left 100%;background-size:0% 2px,100% 1px;background-repeat:no-repeat;\n  transition:background-size .35s ease;}\n.tlr-cmp a:hover{opacity:1!important;}\n.tlr-cmp .cmp-row:hover .cmp-name a,.tlr-cmp .cmp-name a:hover{background-size:100% 2px,100% 1px;}\n.tlr-cmp .cmp-youre{font-size:10px;letter-spacing:.06em;text-transform:uppercase;color:#9a8e74;font-weight:700;margin-left:7px;}\n.tlr-cmp .cmp-price{color:#a3704d;font-weight:700;font-size:13px;margin:2px 0 3px;}\n.tlr-cmp .cmp-diff{color:#555;font-size:13.5px;line-height:1.45;}\n.tlr-cmp .cmp-verdict{margin:16px 0 4px;font-size:14.5px;line-height:1.5;color:#2a2b2a;}\n.tlr-cmp .cmp-verdict a{color:#a3704d;font-weight:700;\n  background-image:linear-gradient(#a3704d,#a3704d),linear-gradient(#d8c3ac,#d8c3ac);}\n.tlr-cmp .cmp-verdict a:hover{background-size:100% 2px,100% 1px;}\n\u003c\/style\u003e\n\u003ch5\u003eWhere the Grado SR325 fits in the Grado Classic Series\u003c\/h5\u003e\n\u003cdiv class=\"tlr-cmp\"\u003e\n\u003cp class=\"cmp-sub\"\u003eThe three Classic Series models The Listening Room stocks, priced low to high.
