The Mahogany wood now undergoes a new proprietary curing process that enhances its natural tone properties. Wood, being a product of nature, is subject to variations in density and other properties. Our curing process ensures consistency of the signature Grado sound. Rhodium, the most expensive precious metal on earth, is employed in The e Series headphones to prevent corrosion on connectors, and unwanted graininess in your music.
