[VGP 2024 Gold Award Winner] EarFun Air Pro 4 Wireless Earbuds, Bluetooth 5.4, 50dB Adaptive Hybrid ANC, Cutting-Edge QCC3091 Chipset, aptX Lossless,

[Advanced Technology Solution & aptX Lossless Audio Transmission] EarFun Air Pro 4 uses Qualcomm's cutting-edge chip [QCC3091]. It supports Bluetooth standard (v5.4) and the audio solution [Snapdragon Sound], delivering high-quality sound and low latency. Supports [aptX Lossless], allowing you to enjoy high-quality wireless music playback at 96kHz/24bit (approximately 1.1-1.2Mbps) in a stable wireless environment. It also supports LDAC, transmitting an overwhelming amount of information at a bit rate of 990kbps—approximately three times the data rate of CD (44.1kHz/16bit)—preserving the finest details of your music and allowing you to hear the true, original sound. [Advanced Noise Cancellation / Intelligent Wear Detection] Our unique noise canceling technology has evolved to QuietSmart 3.0. New adaptive noise canceling technology adjusts noise reduction levels based on ambient noise levels, achieving up to 50dB of noise reduction. Intelligent wear detection automatically pauses music when you remove the earphones and resumes playback immediately when you put them back on. [High-quality calls with six microphones and AI technology / Low-latency game mode] Utilizing three high-performance microphones on each side, the headphones support cVc 8.0, which filters out noise from the captured voice. Even in noisy environments, your voice is clearly audible to the other party. By enabling game mode in the EarFun Audio app, you can reduce wireless audio latency to 50ms (0.05 seconds), eliminating noticeable audio and video synchronization issues. [52 Hours of Playtime/IPX5 Waterproof] Thanks to the extremely low power consumption of Qualcomm's S3 third-generation high-performance QCC3091 Bluetooth chip, the Air Pro 4 can be used for 11 hours on a full charge, or 52 hours with the charging box. It supports two charging methods: wireless charging and USB-C. It also supports fast charging, with a 10-minute charge providing 2 hours of use. The earphones are IPX5 waterproof, so you can rest assured even if they get wet or sweat during exercise. Note: The charging box is not waterproof, so please keep it dry. [Supports New LE Audio and Auracast Technologies] Supports the new generation Bluetooth standard LE Audio and AURACAST wireless shared listening technology, opening up new ways to connect with the world. With AURACAST Broadcast, you can join a Wi-Fi network just like searching for one, connect your device, and receive broadcasts (such as boarding broadcasts and waiting broadcasts) without worrying about missing a broadcast. *LE Audio and AURACAST will be available after a firmware update. [Multi-point connection and Google Fast Pair support] Compatible with Bluetooth 5.4, the headphones offer faster and more stable connections. In addition to the multi-point function that allows you to connect two devices simultaneously, they also support Google Fast Pair, which allows for quick and easy pairing with Android devices. Note: ① If one of the earphones does not light up and you cannot connect, please reset it. Contact customer service to confirm the correct reset procedure. ② Our firmware is continuously upgraded. Because there will be many firmware updates in the early stages, there is a small chance that updates across multiple versions may fail. If this fails, reset the earphones and try the update again. ③ Due to technical limitations, LDAC is prone to signal blockage. Please keep the device and earphones within a range of 1 meter and remove any obstructions. You can also change the LDAC bitrate to 330kbps in your device's developer options. If blockage persists, try using another codec such as aptX.
