About the SR325

The Grado SR-325 is a premium headphone model in Grado's Prestige Series, first introduced in the late 1990s and refined through various iterations including the SR325i and SR325x. It features an open-back, on-ear design with metal housings that enhance durability and sound accuracy. The headphones use Grado's 4th generation 44mm dynamic drivers, specifically tuned for this model, offering improved dynamics, efficiency, and lower distortion. The SR-325 delivers a detailed and engaging sound signature with tight, fast bass, forward and highly detailed mids, and a natural presentation. It has a frequency response of 18Hz to 24kHz, sensitivity around 98-99.8 dB SPL at 1mW, and impedance typically around 32 to 38 ohms depending on the version. The headphones are known for excellent stereo imaging and a wide, open soundstage. The build includes a metal housing, adjustable headband with cushioning, and an eight-conductor super annealed copper cable terminating in a 3.5mm plug with a 1/4" adapter included. The SR-325 is favored by audiophiles for its balance of performance, durability, and classic Grado sound character. Variants like the SR325x add refinements such as improved drivers and all-metal housing for enhanced layering and accuracy. The SR325i version features driver improvements for lower transient distortion and a gold housing commemorating Grado's 50th anniversary. Overall, the SR-325 series remains a hallmark of Grado's Prestige line, offering a premium listening experience with detailed sound and robust build quality.
