SR325

Precision in Aluminum

Few headphones in the Grado lineup carry the recognition of the SR325.

For decades it has been consistently ranked among the best headphones in its price category by leading consumer reporting publications, earning a reputation for clarity, speed, and engaging musical detail.

The SR325 represents a step forward in the Classic Series lineup, pairing the refined X2 driver platform with a precision-machined aluminum housing.

44mm X2 Dynamic Driver

The SR325 uses Grado’s 44mm X2 dynamic driver incorporating a Mylar diaphragm, copper voice coil, and rare earth magnet system engineered for efficiency and control.

The tuning emphasizes articulation and speed, delivering tight bass response, forward midrange clarity, and crisp high-frequency extension.

Signature Silver Headband Assembly

The SR325 incorporates Grado’s Signature Silver headband assembly developed from the same engineering platform as the Signature Gold system.

The assembly utilizes engraved reinforced polymer gimbals and junction blocks, maintaining the improved geometry and controlled rotation of the Gold platform while reducing weight.

A genuine leather headstrap with contrasting white stitching improves comfort, while the internal steel spring band allows listeners to easily adjust clamping pressure.

Signature Silver Cable

The SR325 is supplied with Grado’s Signature Silver cable offering reduced weight and improved flexibility compared with earlier designs.

F Cushions

The SR325 ships standard with Grado F cushions reinforcing its immediate and energetic presentation.

Grado cushions also serve as a tuning element allowing listeners to personalize their listening experience.

Aluminum Housing

The SR325 features a precision-machined aluminum housing designed to reduce unwanted resonance while supporting a fast and controlled presentation.
