【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 is a USB powered speaker that supplies power from the USB port. Since it does not require AC power, wiring is simple and installation is easy. A large capacitor is installed inside to achieve surprisingly high output that cannot be output with conventional USB-powered speakers. Equipped with a "PRAC (Power Reserving Amplifier Circuit)" circuit that enables high output when necessary by charging power in the capacitor. The sound source output is a 3.5mm stereo mini jack connection, so you can enjoy music just by connecting it to the audio terminal of your computer, TV, etc. Equipped with a BASS control, you can adjust the sound quality to your preference. It is equipped with an external input terminal (AUX IN) on the front. You can easily connect your smartphone and enjoy music.
