Welcome to MJ Select. We are Japanese seller. We ship authentic items from Japan. Please enjoy shopping with peace of mind!

【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.

With its compact and highly portable design, excellent sound quality, comfortable fit, and convenient included case, you can take it anywhere and enjoy music comfortably even during long listening sessions.
