Grado Prestige Series SR225x Headphones

With specially tuned 4th generation de-stressed drivers, a special F cushion, an improved headband, and eight-conductor cable

Handmade in Brooklyn, the SR225x is the last stop before getting into the Grado's wood and metal offerings. The SR225x offers 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 SR225x. 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 new headband offers more cushion.

The SR225x offers a higher upper frequency response, and the drivers are matched to within 0.05 dB versus the 0.1 dB of the lower models in the range.
