Introduced in March 2009, the PS1000 is the second high end circumaural headphone, and current flagship from Grado Labs. Featuring the same oversized pads and body design as the previous flagship the GS1000, the PS1000 features an enclosure with a metal exterior and a wooden interior for the combined qualities both materials exert on the sound signature. Considered by the majority of those lucky enough to hear them to be the best Grado has designed (including such rarities as the PS1 and HP-1000). The PS1000 also feature a price tag to match. At $1650, the PS1000 match other high end flagship headphones such as the HD800.
