---------------------------------------------------------------------- 【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 an ultra-powerful chip] The S9 Pro Plus uses the DAC chip ES9038Q2M, which supports PCM sampling rates up to 32-bit/768kHz, and achieves perfect reproduction of sound sources with a high signal-to-noise ratio of up to 128dB and ultra-low THD+N of -120dB. 【Strong Output Efficiency】138mW+138mW@32Ω 3.5mm SE /180mW+180mW@32Ω 4.4mm BAL, easily drives low impedance IEMs, headphones.
