【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.

✅【COMFORT AND SAFETY】KING LUCKY i31 wireless earphones are made of shape memory alloy wire and high quality silicone material. By adopting an open ear design that is soft and can change its shape freely, the biggest feature is that it is gentle on the ears and does not easily fall off. Compared to in-ear and bone conduction types, there is less pressure on the auricle and external auditory canal, making them not only more comfortable to wear, but also reducing the impact on your hearing. For people who want to exercise or do housework while listening to music, it is safe and secure because they can hear outside sounds without any problems and can respond smoothly to the surrounding situation.
✅ [High-quality music playback and voice calls] Equipped with a large-diameter 16.2mm dynamic driver, you can enjoy deep bass and clear, loss-free surround sound. In addition, it is equipped with a dual-microphone noise reduction system based on proprietary technology that suppresses surrounding noise and accurately captures human voices, allowing clear and realistic audio to be transmitted to the other party. Furthermore, technology that controls directivity minimizes sound leakage. (Due to the type of structure that does not cover your ears, it is not possible to completely prevent sound leakage, so please be careful about the volume in environments where there are people nearby, such as on trains or cafes.)
✅ [High-speed and stable connection] Adopts Bluetooth 5.3, ensuring high-speed transmission and stable connection with various Bluetooth-compatible electronic devices such as iPhone, Android, Windows, and iOS within a range of 10 meters, with almost no delays or skipping. Pairing with the device to be connected is done only once for the first time, and from the second time onward, the pairing will be done automatically by simply opening the charging case and taking out the earphones.
✅【Easy Operation and Sweatproof and Waterproof】Smart touch operations with just a light touch allow you to easily play/pause music, adjust volume, and answer/end calls. In addition, it is compliant with IPX5 waterproof standards and is durable enough to withstand rain and sweat during exercise.
✅ [Long time playback of 36 hours] Up to 8 hours of music playback is possible with the earphones alone, and up to 36 hours of playback is possible when used with the charging case. In addition to Japanese voice guidance, it also supports Siri and Google Assistant.
✅ [Certified] Radio law technical compliance certification number: 214-230270.
