FeatherBA™ + 10mm Dynamic Hybrid Driver System
The EarFun Air Pro 4+ features a sophisticated Dual-Driver System combining EarFun’s ultra-light FeatherBA™ Balanced Armature with a powerful 10mm composite dynamic driver. The dynamic driver is engineered to produce resonant, controlled low frequencies and natural midrange reproduction, while the balanced armature focuses on detailed and crisp high frequencies. Together, they create a full-spectrum listening experience with excellent separation, allowing subtle instrumental details, vocals, and powerful bass elements to be reproduced with greater clarity.
Nano Side-Fitted Acoustic Architecture
EarFun introduces its innovative Nano Side-Fitted Acoustic Architecture (NSAA™) to further optimize the performance of the hybrid driver configuration. The dynamic driver and FeatherBA™ Balanced Armature are positioned with an approximately 11-degree alignment, helping minimize unwanted acoustic interference between the two drivers. This carefully engineered arrangement allows the Air Pro 4+ to produce cleaner treble, accurate tonal reproduction, and a more coherent full-frequency listening experience while maintaining the benefits of its dual-driver architecture.
QuietSmart™ 3.0 Adaptive Hybrid ANC
For listening in noisy environments, the Air Pro 4+ features QuietSmart™ 3.0 Adaptive Hybrid Active Noise Cancellation capable of reducing environmental noise by up to 50dB. EarFun uses a six-microphone array with real-time processing that can adapt to changing environmental conditions approximately every 0.3 seconds. The ANC system operates across a noise-cancellation frequency range reaching approximately 4000Hz, helping suppress a variety of distracting sounds while commuting, travelling, working, studying, or relaxing.
Hi-Res Audio with aptX Lossless & LDAC
The EarFun Air Pro 4+ supports an extensive collection of premium wireless audio technologies. Its codec support includes aptX Lossless, aptX Adaptive, LDAC, LC3, and Auracast™, while the earbuds are also Hi-Res Audio certified. LDAC enables higher-bandwidth wireless audio transmission, while Qualcomm Snapdragon Sound and aptX Lossless provide advanced audio capabilities when paired with compatible source devices. This broad codec support makes the Air Pro 4+ suitable for users who prioritize detail, clarity, and high-quality wireless music playback.
Bluetooth 6.0, 6-Mic AI Calls & <50ms Gaming
Powered by the Qualcomm QCC3091 SoC and Bluetooth 6.0, the Air Pro 4+ delivers modern wireless connectivity for compatible devices. Its enhanced 6-microphone AI Clear Call system with cVc™ 8.0 technology helps reduce wind and background noise while maintaining natural voice transmission during calls. For gaming and video entertainment, an ultra-low latency mode below 50ms improves synchronization between audio and on-screen action. Multipoint connectivity, Google Fast Pair, Auracast, and smart in-ear detection add further everyday convenience.
54H Battery, Fast Charging & IP55 Protection
With ANC disabled, the EarFun Air Pro 4+ provides up to 12 hours of playback from the earbuds and up to 54 hours total with the charging case. With ANC enabled, single-charge playback reaches approximately 8 hours, with up to 36 hours total through the case. Fast charging can provide approximately 3 hours of playback from only 10 minutes of charging, while both USB Type-C and wireless case charging are supported. An IP55 water and dust resistance rating provides additional protection for workouts, commuting, and outdoor everyday use.
