Grado has taken one of the world's most legendary headphones and made it even better. The SR60e has a new driver design, a new polymer to better damp resonant distortion in the plastic housing, and a new cable from plug to driver connection. The way the SR60e's new driver and 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 and lower range of the frequency spectrum, while supporting Grado's world renowned midrange. The SR60e will produce a sound that is pure Grado, with warm harmonic colors, rich full bodied vocals, excellent dynamics, and an ultra-smooth top end.
