The SR325is from Grado is a top-of-the-line stereo headphone that's perfect for working in a studio or for casual listening. Based on the SR325i, Grado has looked at their previous model and taken steps to improve the drivers and cable even further. The physical design is constructed for long-lasting comfort, with an adjustable headband and soft, cushioned foam earpads.
The SR325is has several features that provide the ultimate sonic experience, with terrific clarity and detail. Upgraded drivers are matched within 0.05dB and the mass distribution in the aluminum housing has been improved. The vented diaphragms have been "de-stressed" to provide great detail, and the voice coil and 8-conductor connecting cord are both made from ultra-high purity long crystal copper wiring.
