Grado Prestige Series SR325x Headphones

With a metal housing, specially tuned 4th generation de-stressed drivers,  eight-conductor cable, and a leather headband

Handmade in Brooklyn, the SR325x is the flagship of the Prestige Series. The metal enclosure offers an incisive, high-bandwidth sound, but without losing Grado's world-renowned harmonic colors, full-bodied vocals, and rich mid-range. 

The fourth-generation 44 mm Grado drivers are carefully matched, and specifically tuned for the SR325x. The new design has a more powerful magnet, a voice coil with decreased effective mass, and a reconfigured diaphragm.

The new eight-conductor cable is housed in a more durable exterior, and uses a super annealed copper wire for improved signal purity. The leather headband features white accent stitching.

The SR325x offers a higher upper and lower frequency response than the rest of the range. As with the 225x, the drivers are matched to within 0.05 dB versus the 0.1 dB of the lower models in the range.
