Fostex T50RPmk4

Building on a storied lineage dating back to 1974, the Fostex T50RPmk4 represents the latest evolution of the renowned RP series headphones. This 4th generation model surrounds your ears with Fostex’s most advanced planar magnetic drivers yet, offering jaw-dropping detail and accuracy prized by audio professionals and enthusiasts alike. Whether tracking or mixing in the studio or simply immersing yourself in your music library, the T50RPmk4 delivers an uncompromising listening experience.

Fostex’s Finest Planar Magnetic Driver Yet

At the heart of the T50RPmk4 beats a brand-new 4th generation RP driver fine-tuned for optimal performance. The flat diaphragm features an expanded, equalized vibration area outlined by a redesigned printed coil pattern. This coil is sandwiched between a substantially increased array of magnets carefully mapped to optimize flux distribution. The result of these driver innovations is remarkably linear, low-distortion response with stellar transient characteristics. You’ll experience a smooth, extended frequency range along with a spacious yet focused soundstage.

Symmetrical Design Ensures Consistent Sound

The housings for both the left and right drivers are engineered to be perfectly symmetrical. Not only does this allow you to connect the included cable to either side for convenience, but it eliminates any potential sonic differences between channels. You can expect utterly consistent imaging and tonality regardless of cable routing. The 4-pole 3.5 mm connector supports balanced audio connections for further sonic purity.

High-Performance Cabling Optimized for Planar Magnetics

To complement the T50RPmk4’s cutting-edge drivers, Fostex includes a high-quality OFC cable engineered specifically for planar magnetic headphone use. The oxygen-free copper conductors maximize signal transfer while remaining flexible and low-microphonic. For further performance gains, you can upgrade to Fostex’s optional balanced cables featuring 2.5 mm, 4.4 mm or XLR terminations. Balanced connections eliminate noise interference for an even cleaner signal path.

Luxurious Comfort for Marathon Listening Sessions

Thanks to the T50RPmk4’s thick, low-resilience around-ear pads, you can listen for hours without fatigue. The plush cushions gently surround your ears, providing an immersive experience free of hot spots or pressure points. The large, open-back earcups create an airy, spacious soundstage ideal for analytical listening. Despite housing massive planar drivers, the T50RPmk4 remains lightweight and well-balanced for extended wear.
