【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.

[About clocks that synchronize time via radio waves] The function of clocks that synchronize time via radio waves only works in the Japanese area. Please be careful. 🏅 [Advanced Technology Solutions & aptX Lossless Lossless Audio Transmission] EarFun Air Pro 4 won the "VGP Gold Award" for two consecutive years in 2024 and 2025, and also won the "Cospa Grand Prize" in 2025. Equipped with Qualcomm's cutting-edge chip "QCC3091", it supports the latest Bluetooth standard (v5.4) and audio solution "Snapdragon Sound". It achieves both high sound quality and ultra-low latency. It supports "aptX Lossless", and you can enjoy high-quality music wireless playback of up to 96kHz/24bit (approximately 1.1 to 1.2Mbps) in a stable wireless communication environment. It also supports LDAC, transmitting an overwhelming amount of information, about three times that of CD (44.1kHz/16bit), at a bit rate of up to 990kbps, preserving the details of the music and allowing you to hear the true original sound. 🏅 [Advanced noise canceling / Intelligent wearing detection function] Our unique noise canceling technology has evolved into "QuietSmart 3.0". We have also introduced a new "adaptive noise canceling technology" that changes the noise reduction level according to the surrounding noise level, achieving noise reduction of up to 50dB. It is also equipped with an intelligent wearing detection function, so music is automatically paused when the earphones are removed and resumes playback as soon as they are put back on. 🏅 [6 microphones + AI technology for high-quality calls / Low latency game mode] Utilizing three high-performance microphones on each side, it supports "cVc 8.0" which removes noise from the collected voice. Even in noisy environments, you can deliver a voice that is easy to hear to the other party. By turning on game mode in the "EarFun Audio" app, you can reduce the wireless audio latency to a maximum of 50ms (0.05 seconds), so you won't have to worry about out-of-sync audio and video. 🏅【Up to 52 hours of long-term playback/IPX5 waterproof performance】Based on the extremely low power consumption of Qualcomm's latest S3 3rd generation high-performance QCC3091 Bluetooth chip, the Air Pro 4 can be used for up to 11 hours on a full charge, and up to 52 hours with the charging box. Supports two charging methods: wireless charging and USB-C charging. It also supports fast charging, and can be used for 2 hours with 10 minutes of charging. The earphones have IPX5 waterproof performance, so you can rest assured that they will not get wet or sweat during exercise. Note: The charging box is not waterproof, so please keep the charging box dry. 🏅 [Supports new technologies LE Audio and Auracast] Supports the new generation Bluetooth standard LE Audio and AURACAST wireless shared listening technology, opening new ways to connect with the world. With AURACAST broadcasting, you can join as if you were searching for a Wi-Fi network, connect your device and receive broadcasts (such as boarding broadcasts and waiting broadcasts), so you don't have to worry about missing the broadcast. * LE Audio and AURACAST will be available after the firmware is updated. 🏅【Multi-point connection and Google Fast Pair support】Supports the latest Bluetooth 5.4, making connections faster and more stable. In addition to the multi-point function that allows you to connect two devices at the same time, it also supports Google Fast Pair, which allows you to pair with Android devices quickly and comfortably. Note: ① If one of the earphones does not light up and cannot be connected, please reset it. Please contact customer service to confirm the correct reset procedure. ② Our firmware is upgraded continuously. Since there are many firmware updates in the beginning, there is a small probability that updates across multiple versions may fail. If it fails, reset the earphones and try updating again. ③To use the aptX Lossless and LDAC codecs, you need a device that supports them. You also need to install the EarFun Audio app on your Android smartphone and enable LDAC using the app (aptX Lossless is enabled by default). LDAC and aptX Lossless cannot be used on iOS systems such as iPhone and iPad. ④Due to technical limitations, LDAC is prone to signal clogging, so keep your device and earphones within a 1 meter range and remove any obstacles. You can also change the bit rate of LDAC to 330kbps in the developer options of your device. If clogging is still severe, try using other codecs such as aptX. ④ Keep the earphones clean and dry, and regularly clean them of sweat, dirt, and other foreign matter. ⑤ When connecting multiple devices, the earphone volume may be synchronized to one of the connected devices. To prevent discomfort when switching, be careful not to let the volume difference between the devices become too large. ⑥ When using the earphones, avoid crowded environments and environments with strong radio interference such as Wi-Fi routers and microwave ovens. ⑦ If a problem occurs with the earphones, update the firmware, reset the earphones, delete the old Bluetooth pairing record, and then reconnect.
