The Fostex RPmk3 series headphones are successors to the reputed RPmk2 series.
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.
