【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.

Note: ① If one earphone does not light up and cannot be connected, please reset it. Please contact customer service to determine the correct reset procedure. ②Our firmware will continue to be upgraded. Since many firmware updates are performed initially, there is a small chance that updates that span multiple versions will fail. If it fails, please reset the earphones and try updating again and again.
③To use the aptX Lossless and LDAC codecs, you need a device that supports those codecs. You will also need to install the EarFun Audio app on your Android smartphone and use that app to enable LDAC (aptX Lossless is enabled by default). LDAC and aptX Lossless are not available on iOS systems such as iPhone and iPad. ④Due to technical limitations, LDAC is prone to signal blockages, so please use the device and earphones within a 1 meter range and remove obstacles. You can also change the LDAC bit rate to 330kbps in your device's developer options. If the blockage is still severe, try using another codec such as aptX.
