Hi-Fi Choice

 Fostex have long since used RP (Regular Phase) diaphragm technology in their acclaimed professional studio headphones such as the T20RPmk2 and the recent T-series models.

The new TH500RP model now combines this RP technology with the design philosophy and flair of the TH900, resulting in a set premium headphones which deliver a simply stunning high resolution sound, with sparkling highs, rich mid tones and high quality lows.

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.
