The Fostex T20RPMK3 is a professional open-back studio headphone built around Fostex's legendary RP (Regular Phase) planar magnetic technology. Its RP diaphragm — a polyimide film base etched with copper foil — delivers exceptional transient response, extended high-frequency detail, and powerful low frequencies that dynamic drivers struggle to match. With a wide frequency response of 15 to 35,000 Hz, 92dB/mW sensitivity, and a maximum input of 3,000mW, the T20RPMK3 handles everything from delicate acoustic work to high-volume monitoring with ease, while low-resilience urethane earpads ensure comfort through long studio sessions.
