Fostex T50RP MK3 Planar Magnetic Over-the-Ear Headphone

  • Refined Fostex proprietary Regular Phase (RP) diaphragm driver using copper foil etched polyimide film and powerful neodymium magnet

  • The maximum input level of 3000mW to comply with various professional uses

  • Offering Semi-Open for “Flat and Clear” sound

  • Newly developed low repulsion ear pad and head pad for maximum comfort

  • Comes with 3m 1/4” plug detachable cable for best serviceability and 1.2m mini plug cable for portable audio use



The Fostex RPmk3 series headphones are successors to the reputed RPmk2 series, which for more than 30 years (including from the start of the T-series) have been used as reliable monitor headphones by professional recording studios across the globe. The unique planar-magnetic (also known as orthodynamic) driver unit incorporates Fostex's proprietary Regular Phase (RP) Technology diaphragm, which is delicately refined to achieve sharper audio reproduction for more accurate monitoring. The housing, ear pads, and head pad have also been redesigned both to derive the maximum performance of the RP driver, and provide maximum comfort for the listener.
