Each set of PS500 headphones is hand-crafted by Grado Labs in Brooklyn, New York. Its outer earcup housings are made of metal alloy, then fitted with an inner sleeve of specially cured mahogany wood. This combination of proprietary materials creates an air chamber that resists unwanted vibration, to ensure your sound remains unaffected by coloration and distortion. Like all Grado headphones, the PS500 uses a vented "open-air" earcup design with large, non-resonant air chambers for powerful, extended bass response and more open, spacious sound. The headphone's wide frequency range ensures you'll hear all of your music. Another nice touch is the genuine leather headband, which you can adjust for a custom fit.
These impressive 'phones work with the headphone outputs on most home audio systems, but to really hear them in all their glory we strongly recommend a headphone amplifier.
