【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 a well-balanced sound from high to low frequencies, you can enjoy natural and clear vocals and instruments.

It reproduces compressed audio sources such as streaming, MP3, and Bluetooth transmission codecs with a spacious and excellent sound. It is compatible with a dedicated app, and by using the "equalizer" that allows you to customize the sound quality to your liking, you can choose from eight different presets such as "Relaxed" and "Bass Boost," or customize the equalizer settings to your preference.
