【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. Equipped with the "MA12070" new amplifier IC, this latest circuit design allows it to achieve an ultra-low distortion rating of 0.005%, which is even higher than the A100, and provides high quality sound quality and excellent audio performance with an energy conversion efficiency of 92%! Combining aesthetics and practicality, compatible with Bluetooth 5.0, but without antenna!
