Grado SR325 Classic Series Open-Back Headphones

Grado SR325 Classic Series Open-Back Headphones

The Grado SR325 Classic is the metal-housed flagship of Grado’s current SR lineup, combining the company’s open-air headphone architecture with a precision-machined aluminum housing, 44mm X2 dynamic drivers, Signature Silver headband hardware, Signature Silver cable, and F cushions. The result is a fast, immediate and highly articulate presentation designed for listeners who want the energetic character of Grado headphones with greater refinement in materials and construction.

For listeners familiar with the previous Grado SR325x, the new SR325 Classic is the current-generation successor. It preserves the SR325 family’s long-standing emphasis on speed, clarity and direct musical engagement while moving the model into Grado’s latest Classic Series platform.

44mm X2 Dynamic Driver

The SR325 uses Grado’s 44mm X2 dynamic driver, incorporating a Mylar diaphragm, copper voice coil and rare-earth magnetic system engineered for efficiency and control. Grado tunes the SR325 for articulation and speed, with tight bass response, forward midrange clarity and crisp high-frequency extension.

Precision-Machined Aluminum Housing

The defining structural feature of the SR325 is its precision-machined aluminum housing. The rigid metal earcups are designed to reduce unwanted resonance and support a fast, controlled presentation while giving the SR325 a distinctly premium feel compared with molded-housing models lower in the Classic Series.

Signature Silver Headband Assembly

The SR325 incorporates Grado’s Signature Silver headband assembly, developed from the same engineering platform as the company’s Signature Gold system. Engraved reinforced-polymer gimbals and junction blocks maintain improved geometry and controlled rotation while reducing unnecessary weight. A genuine leather headstrap with contrasting white stitching improves comfort, and the internal steel spring band allows listeners to adjust clamping pressure to suit their fit.

Signature Silver Cable

Grado equips the SR325 with its fixed Signature Silver cable, designed for reduced weight and improved flexibility compared with earlier cable designs. The standard connection uses a 3.5mm plug with a removable 1/4-inch adapter for compatibility with portable sources, dedicated headphone amplifiers and traditional home audio components.

F Cushions

The SR325 ships with Grado F cushions, positioning the drivers close to the ear and reinforcing the headphone’s immediate, energetic presentation. Grado cushions also function as part of the acoustic tuning system, allowing compatible cushion changes to subtly alter tonal balance and spatial presentation.

Open-Back Grado Sound

The SR325’s open-air design allows the drivers to breathe freely rather than trapping energy inside a sealed earcup. This architecture supports the spacious, lively and direct presentation associated with Grado open-back headphones, with strong separation between instruments and vocals and a natural sense of air around recordings.

Who Is the Grado SR325 Classic For?

The SR325 Classic is designed for listeners who want a more premium expression of Grado’s traditional open-back sound without stepping into the wood-housed models above it.
