What does the i stand for in the new SR80i from Grado? Improved, that's what! Built on the same features as theSR60i, but SR80i utilizes a 4 conductor connecting cable and the diaphragms are put through a special 'de-stressing' process in order to enhance inner detail, the result of which gives a more open stage. The new SR80i has an upgraded driver design, and they have enlarged and improved the mass distribution in the plastic housing. The way the SR80i's new driver and plastic housing move air and react to sound vibrations are now less affected by transient distortions. The SR80 provides an improved bass resonance, which enhances the overall detail. With the SR80i you will notice improved control of the upper and lower range of the frequency spectrum with both better supporting Grado's world renowned midrange. The SR80i 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!
