The new SR325i has an upgraded driver design, and they have enlarged and improved the mass distribution in the metal housing. The way the SR325i’s new driver and metal housing move air and react to sound vibrations are now less affected by transient distortions. With the SR325i you will notice improved control of the upper and lower range of the frequency spectrum with both better supporting Grado’s world renowned midrange. And why the Gold color? The new SR325i is in honor of their 50th anniversary celebrated recently. The SR325i will produce a sound that is pure Grado, warm harmonic color, rich full bodied vocals, excellent dynamics and an ultra smooth top end. Listen and Enjoy
