RP-Series Professional Headphones

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.

Avoid an extended use at high volume levels as your hearing may be permanently impaired. You are advised never to use headphones in such situations as driving vehicle and cycling as your ability to react to emergencies will be considerably reduced.

On rare occasions, noise may occur when the headphone plug is connected and turned 90 degrees to lock it. Unless noise is heard with the plug in the locked position, it is not a problem. However, if noise or uneven reproduction volume occurs, there is a possibility that the headphone plug has become dirty. In such a case, wipe the plug with a dry cloth.
