Grado has taken one of the world's most legendary headphones & made it even better. The SR60e has a new driver design, a new polymer to better damp resonant distortion in the plastic housing, & a new cable design from plug to driver connection. The way the SR60e's new driver & plastic housing move air and react to sound vibrations virtually eliminate transient distortions. This allows the signal flow over the new cable to reproduce sound that has tight control of the upper & lower range of the frequency spectrum, while supporting Grado's world renowned mid-range. It will produce a sound that is pure Grado style, with warm harmonic colors, rich full bodied vocals, premium dynamics, and an very smooth top end.
