Prestige Series SR225x headphones
A unique voice
The SR225x sits a step above the SR125x in the Prestige Series, using the F cushion to open up the sound to more textured tones. The driver and cushion work together to produce a distinct voicing while maintaining the same speed and responsiveness as its sibling.
- Hand-built in Brooklyn
- 8 conductor cable
- F cushion
- Drivers matched to 0.05 dB
- De-stressed driver
Signature sound
The driver and housing work in tandem to react to sound vibrations and virtually eliminate transient distortions. The result is warm harmonic colour, a smooth top end, excellent dynamics, and Grado's renowned midrange — a sound capable of revealing new detail in familiar recordings.
X Series driver
The 4th generation X Series driver is specifically tuned for the SR225x. It features a more powerful magnetic circuit, a voice coil with decreased effective mass, and a reconfigured diaphragm. These changes to the 44 mm driver improve efficiency, reduce distortion, and preserve the harmonic integrity of the music.
New cables and headband
The 8-conductor cable is housed in a more durable exterior and uses super annealed copper wire for improved signal purity. The redesigned headband adds extra cushioning for a more comfortable fit.
Hand-built in Brooklyn
Every SR225x is hand-built by the Grado team in Brooklyn, passing from workbench to workbench before it leaves the factory. Grado has been building headphones since 1953, and that experience feeds directly into every SR225x made today.
