GRADO Classic SR325 Precision in Aluminum Few headphones in the Grado lineup carry the recognition of the SR325. Consistently ranked among the best headphones in its price category by leading consumer reporting publications, the SR325 has earned a lasting reputation for clarity, speed, and engaging musical detail. It represents a meaningful step forward in the Classic Series — pairing the refined X2 driver platform with a precision-machined aluminum housing. 44mm X2 Dynamic Driver Mylar diaphragm, copper voice coil, and rare earth magnet system tuned for articulation and speed. Tight bass response, forward midrange clarity, and crisp high-frequency extension — with a tighter ±0.05 dB driver match for exceptional channel consistency. Precision Aluminum Housing Machined aluminum construction delivers a premium feel and improved acoustic rigidity compared to molded housings. The open-back architecture allows music to breathe naturally, producing the spacious presentation Grado is known for. Signature Silver Headband Engineered from the same platform as the Signature Gold system, with engraved reinforced polymer gimbals and junction blocks. A genuine leather headstrap with contrasting white stitching and an internal steel spring band allow easy clamping pressure adjustment. Signature Silver Cable Grado’s Signature Silver cable offers reduced weight and improved flexibility compared with earlier designs — a refined connection that complements the SR325’s elevated build quality. F Cushions — Tunable Ships with Grado F cushions, reinforcing the SR325’s immediate and energetic presentation. Cushions also serve as a tuning element — experiment with different styles to personalize tonal balance and soundstage.
