EarFun Air Pro 4+ Wireless Earbuds - Bluetooth 6.0 (Black)

・【1BA + 1DD Hybrid Design for More Natural and Realistic Sound】 Equipped with EarFun’s unique “BassSurge” low-frequency enhancement technology, the 10mm dynamic driver powerfully reproduces deep mid-low frequencies. Meanwhile, the company’s independently developed ultra-small balanced armature (BA) driver clearly and vividly depicts clear high frequencies. Furthermore, proprietary hybrid driver dedicated tuning and new frequency division technology create an incredibly smooth connection between high and low frequencies. Achieving faithful sound reproduction with a natural integration that eliminates the 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 a limited housing. This maximizes the potential of the hybrid configuration, achieving both extreme sound quality and comfortable wearing experience. ・【Equipped with Cutting-Edge QCC3091 Chip & Hi-Res Audio with aptX Lossless & LDAC】 Qualcomm’s latest QCC3091 chip fully integrates next-generation Bluetooth 6.0 and Snapdragon Sound. By unifying the device and earphones, it simultaneously achieves high sound quality, stable connection, and low power consumption—the ideal for wireless. It also supports aptX Lossless, enabling lossless transmission that reproduces CD-quality signals without loss. It also supports LDAC, a high-quality codec capable of fast transmission up to 990 kbps, which is more than three times the data rate of standard Bluetooth audio codec (SBC), and can reproduce high-resolution audio sources up to 24bit/96kHz. It has also obtained Hi-Res Audio certification from the Japan Audio Society. ※ Note: LDAC, aptX Lossless, and LE Audio cannot be used on iOS devices. Compatible devices are required. If you want to use the codec on other devices from the iOS app, please contact our support. ・【AI Adaptive Noise Cancelling & Wear Detection Function】 Combining QuietSmart 3.0 and AI adaptive hybrid ANC technology, it achieves a maximum noise cancellation of 50dB, individually optimized for users and environments. The wear detection function automatically turns off noise cancellation/ambient sound mode when the earphones are removed and turns it back on when they are put back in. You can also set the app to automatically play/pause media and automatically answer calls. ※ Regarding the wear detection function: Conversation, eating, and head movements may cause misdetection and stop playback or turn off ANC. Please try re-wearing, exchanging the ear tips for the optimal size, or turning off detection in the app. ・【Easily Share Audio with Auracast Support】 Fully compatible with the next-generation Bluetooth audio standard “LE Audio”. Its innovative feature, Auracast, enables an unprecedented music sharing experience. In airports and cafes, you can listen to TV audio or broadcasts with your own earphones, and easily share videos and music with family and friends. Be the first to enjoy the new possibilities of wireless in expanding compatible environments. 【Note】 Using LE Audio requires a LE Audio-compatible smartphone and activation in the [EarFun] app. Auracast reception requires a transmitting device nearby. If your smartphone does not have a screen to search for (scan) Auracast broadcasts, please connect from the “LE Audio” page of the [EarFun] app. ・【Up to 54 Hours of Playback & Multipoint Connection】 The earphones themselves can be played for up to 12 hours. When combined with the charging case, the total playback time reaches up to 54 hours. It supports rapid charging, providing 3 hours of playback with just a 10-minute charge. The charging case supports both wireless charging and USB-C charging. In addition, the [EarFun] Air Pro 4 Plus supports multipoint connection, allowing you to connect up to 2 devices simultaneously. Listen to music on your PC while seamlessly switching to smartphone calls. ※ Simultaneous use of high-quality LDAC and multipoint connection may cause audio interruptions due to connection load. We recommend turning off the multipoint function when enjoying high-quality sound. When using the earphones, avoid crowded environments or environments with strong radio interference. Also, ensure that the earphones and mobile phone have sufficient power 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 is equipped with 6 AI microphones and cVc 8.0 call noise cancellation technology. The AI algorithm automatically detects and processes ambient and speech sounds, transmitting call audio clearly even indoors, outdoors, or in noisy places. The left and right microphones work together to accurately pick up your voice, keeping the other person’s voice clear and easy to hear while providing a natural sound quality for a comfortable calling experience.

【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.
