–Martin Colloms, HI-FI News & Record Review

With the new 8-conductor cable design you will notice improved control and stability of the upper and lower range of the frequency spectrum, with both better supporting Grado’s world-renowned midrange. The diaphragms are put through a special 'de-stressing' process in order to enhance inner detail. The way the SR225i’s new driver, cable and plastic housing move air and react to sound vibrations are now less affected by transient distortions. Bass, midrange and treble are all more open and you will enjoy amazing tonal spread and balance.

Grado headphones can reproduce as natural a soundstage from stereo recordings and provide as much listening pleasure as a good pair of speakers. Grado headphones are free of room effects and placement problems, and they minimize any interference from external noise. They also offer portability and the ability to listen without worrying about the neighbors. With Grado headphones, you will hear recordings with greater clarity and with deeper bass than others! Grado headphones are the antithesis of mass production, as each Grado headphone is hand-assembled and closely scrutinized to meet full performance specifications in the U.S.A.

All Grado headphones have a vented diaphragm design that incorporates a large air chamber. This design concept lowers the frequency resonance (distortion) of the diaphragm and extends bass response. The diaphragm is made of a low mass polymer, carefully formed to broaden resonant modes to reduce their amplitude. The diaphragm mass is determined with the compliance of the suspension in mind so that the desired low frequency resonance is achieved. The diaphragm's total mass is calculated to provide a full 20 KHZ bandwidth, while avoiding break-up at lower frequencies.

The SR225i feature voice-coils that are wound from ultra-high purity, long crystal (UHPLC) oxygen-free copper. The copper is slowly drawn through the die in extremely small increments and is annealed following each drawing operation. Ultra-high conductivity copper yields the clearest transmission and lowest coloration possible. The sound of UHPLC copper is smoother, cleaner and more dynamic. All use very high power neodymium magnets to provide maximum efficiency and better sound. Each headphone driver is made to Grado's high standards, then pair-matched for exact imaging. These headphones also utilize UHPLC copper in the connecting cable.

Technical refinements for Grado drivers include improved diaphragm and voice coil design for increased bass response and a larger perceived sound stage. A unique process to "de-stress" the diaphragm results in enhanced inner detail. An increased ability to control driver resonance virtually eliminates distortion. For all models, an improved headband spring will afford greater comfort for the majority of listeners.
