About Fostex T50RPmk4

Take your audio experience to the next level with the Fostex T50RPmk4 Semi-Open Back Over-Ear RP Planar Magnetic Headphones in Black. These headphones represent the pinnacle of professional sound quality, comfort, and versatility, making them an ideal choice for musicians, sound engineers, and audiophiles alike. As the latest iteration in a storied lineage that began with the original T50 in 1974, the T50RPmk4 showcases Fostex's dedication to innovation and excellence in headphone technology.

At the heart of the T50RPmk4 is the 4th generation RP planar magnetic driver, a cutting-edge technology that has been meticulously refined over nearly five decades. This driver features a newly designed printed coil pattern that expands and equalizes the vibration area of the flat diaphragm. The enhanced design includes an increased number of magnets sandwiching the diaphragm and a re-engineered magnetic circuit to optimize magnetic flux distribution. These advancements work together to suppress unnecessary resonance and enhance transient response, resulting in improved sensitivity, a smooth frequency response, and superior transient characteristics. The T50RPmk4 delivers accurate and delicate sound reproduction across the entire frequency spectrum, offering an expansive soundstage and precise localization.

The T50RPmk4's symmetrical housing design allows for flexible cable connections on either side, ensuring that sound quality remains uncompromised. Each housing is equipped with connectors for the supplied cable, providing adaptability to suit various usage environments. The 4-pole 3.5mm connector supports balanced connections, and the cable is crafted with high-quality OFC conductors. For those seeking even greater versatility, optional balanced cables are available.

Comfort is a key feature of the T50RPmk4, with newly designed, thicker ear pads that are low-resilience and around-ear type, ensuring a snug and comfortable fit for prolonged listening sessions. Whether you're in the studio or enjoying music at home, the Fostex T50RPmk4 Semi-Open Back Over-Ear RP Planar Magnetic Headphones deliver an exceptional blend of sound quality, comfort, and versatility, making them a standout choice for discerning listeners.
