Description
Designed for listeners who value detail and musical energy over bass weight, the Grado SR325 Classic Series is an open-back headphone that delivers Grado's signature house sound at an accessible price point. Brooklyn-based Grado Labs has refined this model with a 44mm X2 dynamic driver built around a Mylar diaphragm and copper voice coil, engineered to emphasize articulation and speed. The result is a forward, transparent presentation that excels with vocals, acoustic instruments, and jazz ensembles.
The SR325 pairs its aluminum housing with Grado's Signature Silver headband assembly — reinforced polymer gimbals featuring engraved detailing, a leather-wrapped headband with visible white stitching, and an internal steel spring band for adjustable clamping pressure. The included Signature Silver cable is lighter and more pliable than previous Grado cable iterations, while the standard F cushions deliver the brand's characteristic energetic.
At 38 ohms and 98 dB/mW, the SR325 runs easily from phones, laptops, and portable DAPs, yet rewards a dedicated headphone amplifier with improved transparency and control.
