Grado has taken one of the world’s most legendary headphones and taken it a few steps further. The new SR60x has an upgraded driver design, and they have enlarged and improved the mass distribution in the plastic housing. The way the SR60x’s new driver and plastic housing move air and react to sound vibrations are now less affected by transientdistortions. Warm harmonic color, rich full bodied vocals, excellent dynamics and an ultra smooth top end. Listen and Enjoy!
