Ever wondered what hardcore audiophiles are hearing, and that you might be missing? The Grado RS1e is the point of no return so be warned, cross this threshold and you’ll never enjoy mass-market headphones again. Once you’ve experienced this elegant audio masterpiece you’ll grasp the reference. The RS1e from Grado uses a different species of handcrafted mahogany from our previous models. The earpieces utilize an intricate curing process that optimizes the tonal quality while giving them a new look. The RS1e places a 50mm dynamic transducer and an 8 conductor cable design in an open-air configuration. 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. Weighing 9oz, the headphones are an example of the wonders of Mother Nature with a gorgeous light mahogany look. The RS1e is a masterpiece in the Grado collection.
