Fostex T60RPmk2 is a semi-open planar magnetic headphone built around the fourth-generation RP driver in a solid black walnut housing. It is the direct successor to the T60RP — a headphone with a track record in studio listening environments — introducing a new dual-socket Y-cable connection system and a completely redesigned driver. Manufacturing remains fully in-house at Fostex's own factory. The same fourth-generation driver platform underpins both the closed-back T60RPmk2CL and the Japan-made T60RPmk2ai.
Fourth-generation RP driver — what changed from the third generation
The third-generation RP driver served for nearly 20 years as the basis of the T50RP and T60RP lines. The fourth generation introduces a redesigned printed coil pattern — new trace geometry expands and equalizes the vibrating area across the full diaphragm surface. The number of magnets sandwiching the diaphragm has been increased, and the magnetic circuit components were rebuilt to optimize flux distribution, suppressing diaphragm self-resonance modes. The practical results are faster attack and decay, higher sensitivity at the same 28 Ω impedance, and more consistent frequency response — most audible in percussion transients and stereo localization accuracy. At 28 Ω, the T60RPmk2 is driveable from portable DAC/amp combinations and audio interfaces without a dedicated headphone amplifier.Black walnut housing and the new cable system
The semi-open geometry of the T60RPmk2 is a deliberate compromise: wider soundstage and more natural spatial imaging than a closed design, with more defined bass separation than a fully open construction. Solid black walnut provides natural damping of the housing's own resonance modes while contributing a warm midrange character — a complement to the inherently neutral and fast-transient planar drive technology. The new Y-cable system with two independent 3.5 mm TS sockets per earcup replaces the proprietary single connector of the original T60RP, improving third-party cable compatibility. The optional balanced cable ET-RP4.4BL2Y (4.4 mm Pentaconn) is available separately. Optional Ultrasuede EX-EP-RP-SUEDE ear pads are available as an upgrade over the stock low-rebound pads.KEY FEATURES
