What does the i stand for in the new SR125i from Grado? Improved, that’s what! Grado's ability to combine lightness with extreme rigidity and internal damping has been put to good use on the SR125i. Based on the same design as theSR80i, the SR125i also features an improved driver and cable design utilizing UHPLC (Ultra-high purity, long crystal) copper voice coil wire. 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 SR125i’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 the fine tonal spread and balance.

The SR125 has also gained "LEGENDARY" status as has the SR60.
The SR125 has received rave reviews from around the world and is one of the most commonly recommended headphone on the market today.

The SR125 was awarded STEREOPHILE "PRODUCT OF THE YEAR" in two categories, "The Accessory of the Year" and the prestigious "Budget Component of Year".
