---------------------------------------------------------------------- [JOOM-Certified Top Store] 🔹 Operated by a certified Japanese seller. Shop with confidence. ---------------------------------------------------------------------- ------------------------------------------------------------------------------------------------------------------ ★ (While we carry a wide variety of products, the following precautions apply to some of them. Please note that these precautions are listed for all products.) 【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. ------------------------------------------------------------------------------------------------------------------ This Amazon-exclusive set includes the MOMENTUM True Wireless 4 and an aging sound source created by Naoki Endo.
