Key Features
- Adaptive Hybrid Active Noise Cancellation (ANC) up to 50dB – Powered by QuietSmart 3.0 technology, this system continuously monitors external noise and adjusts cancellation strength in real time. It also personalizes performance based on your unique ear canal shape for consistent, effective blocking of low-frequency sounds like airplane engines or subway rumble.
- Qualcomm Snapdragon Sound with aptX Lossless Audio – This certified platform ensures minimal latency, robust signal integrity, and lossless audio quality when paired with compatible Android devices. Combined with support for LE Audio and LC3 codecs, it future-proofs your listening experience across a wide range of sources.
- Hi-Res Audio via LDAC Support – When streaming from high-resolution services like Tidal, Deezer HiFi, or Qobuz, LDAC allows transmission of up to 990kbps bitrate—far exceeding standard SBC—preserving subtle nuances in vocals and instrumentation.
- AI-Powered 6-Mic Call Clarity with cVc 8.0 – Six strategically placed microphones work alongside advanced algorithms to isolate your voice while suppressing wind, traffic, or office chatter. Ideal for professionals making remote calls or content creators recording outdoors.
- Up to 52 Hours Total Playtime – Enjoy 11 hours of continuous playback per charge (earbuds only), extendable to 52 hours with the included USB-C charging case. A quick 10-minute fast charge adds approximately 2 hours of listening time, perfect for tight schedules.
- Bluetooth 5.4 with Multipoint Connection – Connect simultaneously to two devices—like a smartphone and laptop—and switch between them seamlessly without manual reconnection. Optimized for low power draw and rock-solid stability even through walls or crowded areas.
- Auracast Broadcast Audio – Leverage Google’s open-source Auracast protocol to wirelessly share your audio stream with nearby compatible earbuds or hearing aids during events, parties, or group activities—no app required.
- Google Fast Pair Compatibility – Instantly pair with Android devices via NFC-triggered pop-up notifications. No passwords, no menus—just instant connection the first time you tap your phone to the case.
- In-Ear Detection – Automatically pauses music when you remove either earbud and resumes playback upon reinsertion. Conserves battery and prevents accidental touches during commutes or workouts.
- <50ms Low Latency Mode – Activated through the EarFun app, this mode minimizes audio-video sync delays for smoother mobile gaming, TikTok videos, or movie watching on tablets. Near-instant responsiveness keeps action perfectly aligned.
- Customizable Comfort Fit – Includes five sizes of soft silicone ear tips to accommodate various ear shapes and sizes. Ensures a secure seal for optimal bass response and passive noise isolation without pressure buildup.

Benefits & Use Cases
Whether you’re navigating a noisy airport terminal, participating in a virtual meeting from a coffee shop, or simply unwinding with your favorite playlist, the EarFun Air Pro 4 adapts to your needs. The adaptive ANC doesn’t just block loud noises—it learns your daily rhythms, boosting cancellation during flights and dialing it back in quiet libraries or private homes. For travelers, this means deeper immersion during long hauls; for students, clearer focus during study sessions. The <50ms latency mode transforms casual mobile gaming into a responsive, lag-free experience, while Auracast turns social gatherings into shared moments—share concert vibes at a festival or let friends listen along without needing extra gear. Professionals will appreciate the crystal-clear voice pickup in the 6-mic array, which remains effective even in breezy outdoor conditions thanks to AI-driven noise suppression. And because they’re IPX5-rated, they hold up reliably during workouts, rain showers, or unexpected spills. Lightweight yet durable, with an intuitive touch interface and customizable EQ via the companion app, the Air Pro 4 strikes the ideal balance between performance, practicality, and everyday usability.
Important Notes
To ensure optimal performance after firmware updates, always reset the earbuds as instructed in the app. While fully functional with iOS and non-Snapdragon devices, advanced features such as Google Fast Pair, Auracast, and aptX Lossless require compatible Android phones running Android 8.0 or later. The IPX5 rating protects against light splashes and perspiration but not submersion—avoid use during swimming or showering. Battery longevity naturally decreases over time; actual playtime may vary depending on volume level, codec selection, ANC usage, and environmental factors. All specifications reflect internal testing under controlled conditions. Warranty terms and device compatibility lists are provided on product packaging; refer to the included manual for troubleshooting steps and full feature explanations.
