2026 Gold Award Best Value EarFun Air Pro Wireless Bluetooth Hybrid Dual Drivers Smallest Class BA Drivers Chip Supports aptX Lossless LDAC Compatible

--------------------------------------------------- 【Voltage Compatibility】 Our products are selected to support international voltage ranges (e.g. 100–240V). However, please make sure your local voltage is compatible before use, as incorrect voltage may still cause 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 appropriate voltage or equipment. --------------------------------------------------- [1BA + 1DD Hybrid Design for More Natural and Realistic Sound Reproduction] The 10mm dynamic driver is equipped with EarFun's proprietary bass enhancement technology "BassSurge," which powerfully reproduces deep mid-low frequencies. Meanwhile, the company's own developed ultra-compact balanced armature (BA) driver clearly and vividly renders crystal-clear high frequencies. Furthermore, the company's proprietary hybrid driver-specific tuning and new frequency technology create an astonishingly smooth transition between high and low frequencies. This results in a natural, unified sound that is faithful to the original source, without any noticeable boundaries between sounds. The unique off-axis acoustic structure (Nano Side-Fitted Acoustic Architecture, NSAA) precisely positions the dynamic driver and BA driver in optimal locations even within the limited housing. This maximizes the potential of the hybrid configuration, achieving both extreme sound quality and comfortable wear. [High-Resolution Audio Sound with the Cutting-Edge QCC3091 Chip, aptX Lossless & LDAC] Qualcomm's latest QCC3091 chip fully integrates next-generation Bluetooth 6.0 and Snapdragon Sound. By integrating the device and earphones, it achieves the ideal wireless experience of high sound quality, stable connection, and low power consumption. It also supports aptX Lossless, enabling lossless transmission that allows for playback of CD-quality signals without loss. It also supports LDAC, a high-quality audio codec capable of high-speed transmission up to 990 kbps, more than three times the data volume of the standard Bluetooth audio codec (SBC), and can play high-resolution audio sources up to 24-bit/96kHz. It has also obtained Hi-Res Audio certification from the Japan Audio Society. *Note: LDAC, aptX Lossless, and LE Audio are not available on iOS devices. A compatible device is required. If you wish to use codecs on other devices from an iOS app, please contact our support. [AI Adaptive Noise Cancellation & Wear Detection Function] By combining QuietSmart 3.0 with AI adaptive hybrid ANC technology, we have achieved noise cancellation of up to 50dB that is individually optimized according to the user and environment. With the wear detection function, noise cancellation/ambient sound mode automatically turns off when the earphones are removed and turns on when they are put back on. You can also set up automatic media playback/pause and automatic call answering in the app. * To ensure the wear detection function works correctly, please use the optimal size eartips. If you experience noise cancellation problems or music stops, please check the wearing status and consider turning off this function. [Easy Audio Sharing with Auracast] Fully compatible with the next-generation Bluetooth audio standard "LE Audio." Its innovative Auracast feature enables an unprecedented music sharing experience. At airports and cafes, you can listen to TV audio and broadcasts with your own earphones, and easily share videos and music with family and friends. Be among the first to enjoy the new possibilities of wireless in the expanding range of compatible environments. *A compatible device is required to use LE Audio. [Up to 54 Hours Playback & Multipoint Connection] The earbuds offer up to 12 hours of playback on their own. When used with the charging case, the total playback time reaches up to 54 hours. They support fast charging, providing 3 hours of playback with just a 10-minute charge. The charging case supports both wireless and USB-C charging. The EarFun Air Pro 4 Plus also supports multipoint connection, allowing you to connect up to two devices simultaneously. Easily switch between listening to music on your PC and answering calls on your smartphone. *Note: Simultaneous use of high-quality LDAC and multipoint connection may cause audio interruptions due to connection load. For optimal sound quality, we recommend turning off the multipoint function. When using the earbuds, avoid crowded environments and environments with strong radio interference. Also, ensure sufficient power is available on both the earbuds and your mobile phone to avoid a decrease in Bluetooth signal strength due to device power saving. [Clear Calls with 6 Microphones and cVc 8.0] The EarFun Air Pro 4 Plus features six AI microphones and cVc 8.0 call noise cancellation technology. The AI algorithm automatically detects and processes ambient noise and conversation sounds, ensuring clear call transmission indoors, outdoors, and in noisy environments. The left and right microphones work together to accurately pick up your voice, keeping the other person's voice easy to hear while providing a comfortable call experience with natural sound quality.
