The Grado Labs SR125 is an open-air dynamic headphone from the original Prestige Series, introduced around 1993, featuring drivers matched to 0.1 dB, vented and de‑stressed diaphragms, UHPLC (Ultra-high purity, long crystal) copper voice coil wire, and a non-resonant air chamber for low distortion and high detail. Its supra-aural design with adjustable headband and cushioned earcups delivers a lively, natural sound with strong detail, forward mids, and crisp treble that many listeners favor for rock, acoustic, and vocal music. The original SR125 has since been discontinued in favor of later variants such as the SR125i, SR125e, and current SR125x models.
