FOSTEX dynamic RP stereo headphones T50RPmk4 Equipped with a flat diaphragm connection compatible semi-open fully-driven driver/balanced

【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.

【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary.

【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product.

【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. The 4th generation of RP Technology's fully-driven flat diaphragm driver has increased the number of magnets that sandwich the diaphragm and designed a new printed coil pattern to expand and equalize the vibration area of the flat diaphragm. Furthermore, by completely renewing the magnetic circuit components and optimizing the magnetic flux distribution, we have suppressed unnecessary resonance of the diaphragm and achieved a sharp rise and fall of sound with a sharp response. This product is a headphone equipped with a significantly renewed RP driver, which is a fully driven flat diaphragm developed by Fostex. Since being installed in Fostex's first headphone T50 released in 1974, the RP driver has spread to various models and has been recognized by musicians and engineers in music studios around the world as monitor headphones. With the traditional RP driver that has evolved into the 4th generation and an all-new housing design, you can enjoy the next generation of RP headphones that further refine the sound unique to a flat diaphragm. *RP and RP technology are Fostex's proprietary technologies that move the entire surface of a flat diaphragm in a regular phase (Regular Phase).
