Featuring the design philosophy and flair of Fostex's flagship TH900 in a planar magnetic headphone, the TH500RP brings soul and substance to every track. The root of this headphone is the company's Regulated Phase technology: a proprietary transducer and diaphragm design that's used throughout its range of pro-standard microphones, headphones, and loudspeakers. In the enhanced RP diaphragm, copper-foil-etched polyimide film provides strong resistance to high input levels, giving you clear sound no matter how loud you crank it. Retuned for even more power, the TH500RP captures the explosiveness of drums and the nuance of vocals with a clean, well-balanced overall presentation.
