The Grado RS1 is the masterpiece of the Grado collection, the top-of-the-line product which oozes class both in looks and sound. Utilizing handcrafted mahogany earpieces made using an intricate curing process, Grado has been able to optimize the tonal quality and create a distinct luxurious image for this $700 headphone. Only recently outclassed by the $1000 Grado GS-1000, the RS1 still maintains its own distinct smooth, coherent sound with detailed dynamics.
