Featuring a new species of handcrafted Mahogany earpieces made using an intricate curing process; Grado has been able to optimize the tonal quality. The RS1i uses new upgraded dynamic transducers and the new 8 conductor cable design all in an open-air configuration, the cups being open-backed. The result is a smooth, controlled and coherent sound with detailed dynamics. Frequency response ranges from 12-30 kHz and the drivers are matched to 0.05dB.
