■ Voltage Compatibility This product is designed exclusively for use in Japan (AC 100V, 50/60Hz).

Many regions use 120V or 220–240V. Using this product without a proper transformer in such voltage environments may result in malfunction, overheating, or serious and irreversible damage.

■ Plug Type This product uses a Japanese plug (Type A or B). A plug adapter may be required depending on your region.

■ Transformer Requirement (Very Important) A transformer is required for safe use.

A plug adapter only changes the plug shape and DOES NOT convert voltage. Using this product without a transformer may cause serious and irreversible damage.

■ No Return / No Refund Policy We do NOT accept returns or refunds for: ・Voltage mismatch (including 120V and 220–240V environments) ・Use without a transformer ・Plug incompatibility ・Damage caused by improper setup or usage

■ Liability We are not responsible for any damage, malfunction, or performance issues caused by improper use or incorrect voltage conditions.

■ Final Notice Please ensure full understanding of the above before purchasing. Use only under the correct voltage environment. RP Technology's full-range planar diaphragm driver, in its fourth generation, features an increased number of magnets sandwiching the diaphragm and a newly designed printed coil pattern to expand and equalize the vibration range of the planar diaphragm. Furthermore, the components of the magnetic circuit have been completely redesigned to optimize the magnetic flux distribution, suppressing unwanted diaphragm resonance and achieving sharp sound attack and decay. This product is a headphone equipped with a significantly revamped version of Fostex's proprietary full-range planar diaphragm RP driver. Since its introduction in the T50, Fostex's first headphone 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 a monitor headphone. Enjoy the next generation of RP headphones, which further refine the sound unique to planar diaphragms with the evolved fourth-generation RP driver and a completely redesigned housing. *RP and RP technology are Fostex's proprietary technology that moves the entire surface of the planar diaphragm in a regular phase.
