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.
