◆ The T50RPmk3g, as its name suggests, employs a planar diaphragm of the "RP" (Regular Phase: Full-Surface Drive) type, rather than the conventional dynamic type. It further evolves the unique sound of planar diaphragms, setting it apart from conventional dynamic types, and achieves a one-of-a-kind "RP sound." ◆ A major feature of the RP magnetic circuit is that "it obtains a large effective magnetic flux density through the repulsion of the upper and lower magnets, and sandwiches the diaphragm between them." This allows the RP magnetic circuit to "obtain a symmetrical magnetic flux density distribution with respect to the vibration direction of the diaphragm," successfully achieving overwhelming linearity. "Bar-shaped neodymium magnets are used for the magnets, succeeding in obtaining a larger magnetic flux density and significantly improving efficiency." ◆ The zigzag-shaped printed coil pattern ensures uniform movement in the vertical and horizontal directions (no blurring), especially increasing the amount of information in the mid-high frequencies, resulting in excellent vocal realism, for example. Furthermore, by using copper foil for the printed coil material, high input resistance and further sound quality improvement are achieved. The use of polyimide, a highly heat-resistant material known for its reliability, as the base film material provides the high input resistance essential for professional headphones. ◆ High-quality ear pads made of low-resilience urethane are used, allowing for comfortable wear and stress-free monitoring during long hours of recording, mastering, and other tasks. ◆ A single-sided headphone cable that is easy to attach and detach is used. In addition to a Φ6.3mm stereo phone cable (3m), two types of gold-plated plug cables are included: a Φ3.5mm stereo mini phone cable (1.2m).
