Up for sale is a mint-condition pair of Grado SR325x open-back dynamic headphones, the flagship model of Grado’s Prestige Series. Purchased brand new in July 2026 from an authorized dealer and used for only a handful of hours in a dedicated, smoke-free, climate-controlled listening setup. They are in pristine, essentially like-new condition. The brushed aluminum housings have zero dings, scuffs, or blemishes; the factory F-cushions are clean and firm; and the white-stitched genuine leather headband shows no stretching, wear, or creasing. 100% functionally perfect, with Grado's signature punchy dynamics, transparent midrange, and wide open-back imaging.
