What does the i stand for in the new RS2i from Grado? Improved, that's what! The RS2i is the little brother of the RS1i. The RS2i has an upgraded driver and the new 8 conductor cable design. The characteristics of the RS2i remain the same as its distinguished big brother, with the new species of hand crafted mahogany, but with a smaller wooden air chamber. Although a miniature version of the RS1i, the RS2i still maintains an overall sound that is pure Grado, warm harmonic color, full bodied vocals, excellent dynamics and ultra smooth top end. These truly are audiophiles dream.
