Grado PS 500 Professional Headphones (Discontinued by Manufacturer)
Grado releases the little brother of their state-of-the-art PS 1000 Headphones, using trickle-down technology to cut the price by two-thirds, while retaining much of the performance! Also made in America, the new PS 500s are Grado's second offering in their Professional Series line, designed both for the audiophile and recording engineer who value neutrality and high definition over all other design goals. They are an open air design, as are all high end Grado's, and are very light and comfortable. An extraordinary value, and fully appropriate for both reference and critical listening. In the category of musical neutrality for the picky audiophile and the demanding recording engineer, the PS 500s are unsurpassed at this price point.Grado achieved this minor miracle by applying the lessons learned in constructing the wondrous PS 1000s. While still using mahogany to cover the motors, they added aluminum shells to double dampen the housing and kill vibrations. This sandwich design creates the most neutral performance. The large diaphragms contain rare earth metals, including gold wire for maximum definition. The connecting cable is Grado's newest formula, with some fifteen wires enclosed in a proprietary shell. By being American made, they save big bucks from having to import phones from China and can, instead, bulk up on the technology.Specifications - Transducer type dynamic Operating principle open air Frequency Response 14-29 SPL 1mW 98 Normal Impedance 32ohms Driver matched db.05
