EarFun Air Pro 4 Review: Big Features on a Budget
The EarFun Air Pro 4 delivers a surprisingly strong set of features for its price, making it an appealing choice for users who want premium functionality without the premium cost. This fourth-generation model builds on EarFun’s reputation for value, adding aptX Lossless and LDAC codec support, multipoint Bluetooth connectivity, and full EQ customization through the app. Altogether, it feels more advanced than what its budget price tag might suggest.
The earbuds are compact, comfortable, and IPX5 water-resistant, which makes them suitable for both casual wear and light workouts. Sound quality is clean and punchy, especially when using higher-quality codecs, and the ANC does a solid job in everyday environments like commuting or open offices.
Not everything is perfect—touch controls can be too sensitive, call quality dips in noisy settings, and spatial audio is missing. Still, these are minor compared to the overall value and feature set. For around $100, few earbuds match what the Air Pro 4 offers.

How Smart is the AI?
EarFun Air Pro 4
The AI features in the EarFun Air Pro 4 aren’t flashy but are genuinely useful. Adaptive ANC works in the background to modulate noise cancellation strength without user input. It performs well in day-to-day scenarios like commuting or working in open offices, although it doesn’t compete with top-tier ANC systems in more intense environments.
For voice calls, the earbuds use AI to help filter background sound and focus on your speech. It works well in moderately noisy conditions, though performance drops in heavy wind or loud traffic. The AI doesn’t overprocess the voice, which keeps conversations sounding natural even when the system is working.
The EQ suggestions within the app are another example of light but helpful AI. Instead of guessing how to shape your audio, the app recommends settings based on what you typically listen to. It’s a nice touch for users who want better sound but don’t want to dive into manual tweaking.
These features aren’t groundbreaking, but they are well implemented and enhance the overall experience.
Performance & User Experience
EarFun Air Pro 4
Sound Quality & AI Enhancement
The Air Pro 4 delivers a full, balanced sound with enough power to handle a wide range of music styles. The 10mm drivers produce punchy bass, clear mids, and smooth highs, with a tuning that leans slightly warm. Audio stays crisp at moderate volumes and gains additional clarity with aptX Lossless or LDAC.
Through the EarFun app, users get access to multiple EQ presets plus a 10-band manual equalizer. AI-based suggestions help guide users toward genre-specific tuning without needing technical know-how. This flexibility adds real value, especially for a budget-focused product.
Sound quality holds up well during daily use, with only slight distortion at high volumes. There is some audio leakage in quiet spaces if you're listening loud, but for most users and environments, the Air Pro 4 provides excellent audio fidelity for the money.
ANC Performance & Transparency Mode
Active noise cancellation here is surprisingly strong. While EarFun advertises up to 50dB reduction, real-world results hover around 35–40dB. It’s enough to take the edge off public transport, office background noise, and home appliances. The ANC automatically adjusts based on your surroundings and works without major lag or audio artifacts.
Transparency mode is good enough for safety and conversation but isn’t the most natural sounding. Ambient sounds come through slightly processed, especially voices, but it does the job when you need to stay aware.
Transitions between ANC and transparency are smooth, and users can select from multiple ANC levels in the app. This gives flexibility without being overwhelming, though some may find the difference between modes subtle.
Battery Life & Comfort
EarFun Air Pro 4 has battery life that is excellent for the category. You get around 11 hours on a single charge without ANC, and 7.5 hours with it on. The case provides another 35 to 52 hours depending on usage. Fast USB-C charging and Qi wireless support give users multiple charging options.
The earbuds are lightweight and shaped for all-day comfort. They stay secure without putting pressure on the ear canal, making them suitable for extended listening or walking around. The IPX5 rating gives water resistance, making them safe for sweaty workouts or light rain.
Overall comfort and battery performance are two of the biggest strengths of the Air Pro 4.
Microphone & Call Quality
Microphone quality is solid but situational. Indoors or in quiet areas, your voice comes through clearly. Outdoors or in high-traffic spaces, performance dips as the AI struggles to fully isolate speech from louder ambient sounds.
That said, it’s still better than most in this price range. For quick voice messages, calls from a home office, or Zoom meetings, the EarFun Air Pro 4 does the job. Just don’t expect crystal clarity in a windy park or next to a running bus.
Voice assistant access is responsive. Tap-and-hold gestures work consistently with Alexa, Google Assistant, and Siri, allowing you to issue voice commands without touching your phone. For everyday use, this setup is convenient and dependable.
Final Verdict
EarFun Air Pro 4
The EarFun Air Pro 4 hits an impressive sweet spot between price and performance. For under $100, it delivers features usually reserved for more expensive earbuds: LDAC and aptX Lossless support, ANC that actually works, long battery life, multipoint connection, wireless charging, and a surprisingly useful app.
The touch controls could use refinement, call quality could be stronger outdoors, and there’s no spatial audio—but those feel like minor trade-offs in a product this capable. It isn’t trying to compete with flagship earbuds, but it doesn’t need to. It succeeds by offering a balanced, full-featured experience that holds up across real-world usage.
For everyday users who want reliable sound, meaningful noise cancellation, and premium-style features without the premium price, the EarFun Air Pro 4 is easy to recommend. It’s not just good for the price—it’s good, period.
