Finished with a closed-back design featuring beautiful grain and natural texture of solid black walnut wood. Enjoy the rich listening experience unique to closed-back headphones, with deep, solid bass and clear, extended highs free from distortion.

The RP technology planar magnetic driver, which has been continuously improved with proprietary technology for 50 years, has undergone significant enhancements in its 4th generation. To expand and uniformize the vibration area of the planar diaphragm, the magnets sandwiching the diaphragm have been increased, and the printed coil pattern has been redesigned. Additionally, by renewing the magnetic circuit components and optimizing magnetic flux distribution, unwanted resonance of the diaphragm is suppressed, achieving sharp response in sound attack and decay. The 4th generation driver, developed by fully incorporating various technologies cultivated over the years, simultaneously achieves improved sensitivity, smooth frequency characteristics for easier monitoring, and excellent transient response. By enabling accurate and delicate reproduction from deep bass to high frequencies, it further enhances the accurate positioning and sound field reproduction capabilities compared to previous models. As before, consistent quality is ensured through integrated manufacturing at the company’s own factory.

Both left and right housings are equipped with 3.5mm receptacles, adopting a newly developed Y-cable connection. The 2-pole 3.5 mm connector improves recabling compatibility and versatility. The cable features high-quality OFC conductors.
*Optional balanced cables is available: φ4.4mm ET-RP4.4BL2Y
