FOSTEX Sealed Premium Headphones TH900mk2 Onyx Black Mizumezakura lacquered specification

【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.

It offers a premium feel befitting a Made in Japan product that combines traditional crafts. The housing is made of Mizumezakura, a high-quality material with a fine, hard texture and a beautiful surface finish.
