Authors: Kevin W, Marc K, Joan T, Karly R
Introduction
The EarFun Air Pro 4 went from a promising newcomer to undisputed best budget champion of earbuds in 2025! After many weeks of commuting, workouts, voice calls, and binge-listening sessions, we are convinced that no other sub-premium model strikes such a dazzling balance between rich feature depth and everyday reliability.
These earbuds are a polished personal audio companion that repeatedly surprised our review team with flagship-level refinements tucked inside an approachable price tier. It is the definitive choice for anyone seeking high-end performance without the high-end price tag!
Design & Build Quality
EarFun has masterfully blended a familiar, proven design with practical enhancements that prioritize all-day comfort and durability.
​
-
Ergonomics and Comfort: The classic stem-style design is instantly recognizable and incredibly effective. These earbuds are astonishingly lightweight, and our team wore them for entire workdays, during long commutes, and even for late-night listening sessions with minimal fatigue or discomfort. The stability is a standout feature; they remained perfectly secure during vigorous gym workouts and runs, a testament to their thoughtful engineering.
-
Customizable and Secure Fit: A perfect in-ear seal is critical for both sound quality and noise cancellation, and EarFun has gone above and beyond to ensure a perfect fit for almost everyone. The inclusion of five distinct pairs of high-quality silicone ear tips, from extra-small to extra-large, is a generous touch that puts more expensive competitors to shame. In our hands-on testing, this allowed every member of our team to find a deep, secure seal that maximized passive noise isolation and locked the earbuds in place.
-
Durability and Resilience: These earbuds are built for the rigors of real life. The IPX5 water and sweat resistance rating provides genuine peace of mind, offering robust protection against everything from intense workout sessions to getting caught in a sudden downpour. This level of durability is above and beyond the standard for the category and demonstrates a commitment to longevity.
-
Aesthetic and Portability: Available in a range of sophisticated colors like Royal Blue and Purple alongside classic Black and White, the Air Pro 4 has a clean, utilitarian aesthetic that looks great without being overly flashy. The charging case is remarkably compact and pocket-friendly, slipping into a jeans pocket or a small bag almost unnoticed. It’s the perfect companion for a life on the move.
Sound Quality
The EarFun Air Pro 4 delivers an audio experience that is not just great for its class, but genuinely impressive by any standard, offering a level of fidelity and customization that is simply unheard of.
-
Default Sound: Right out of the box, the audio profile is beautifully balanced and versatile. The tuning is clearly inspired by the scientifically-backed Harman target curve, delivering rich, deep bass that is punchy but never bloated, clean and natural mid-tones where vocals and instruments shine, and a bright, lively treble. It’s a safe, pleasing sound that makes every genre of music sound fantastic without any adjustment.
-
Personalization: Here is where the Air Pro 4 truly separates itself from the pack and becomes a giant-killer. The companion EarFun Audio app features a powerful and comprehensive 10-band graphic equalizer, a tool typically reserved for high-end audiophile gear. In our daily use, we found that a few minutes spent tweaking the EQ transformed the already great sound into something genuinely exceptional and perfectly tailored to our personal taste. This feature alone unlocks a level of audio potential that is simply unheard of in this category.
-
Flagship Codec Support: The list of supported audio codecs is astonishing and is the secret to its high-fidelity performance. With support for aptX Lossless, aptX Adaptive, and LDAC, in addition to standard AAC and SBC, the Air Pro 4 is equipped to deliver true, bit-for-bit, CD-quality wireless audio from a compatible device. This is not a gimmick; the difference is audible. The dual Hi-Res Audio and Snapdragon Sound certifications are a testament to the premium-tier audio hardware packed inside.
-
Custom 10mm Drivers: At the heart of the sound are custom-designed 10mm composite dynamic drivers. These powerful drivers are expertly tuned to reproduce the full frequency spectrum with precision and energy, providing the powerful canvas upon which the advanced codecs and custom EQ settings paint their sonic masterpiece.
Active Noise Cancellation
EarFun’s QuietSmart™ 3.0 technology delivers a powerful and adaptive noise-cancellation experience that creates a personal bubble of tranquility wherever you go.
-
Powerful and Effective ANC: The adaptive hybrid ANC system is remarkably potent, capable of dramatically reducing ambient noise. It absolutely excels at silencing the persistent, low-frequency drones of daily life. In our testing, it turned the rumble of a city bus and the hum of an office air conditioner into a barely perceptible whisper, allowing for a truly immersive listening experience. It’s a level of quiet that is simply fantastic for commuting and focusing in loud environments.
-
Intelligent Adaptive Modes: The system offers a suite of intelligent modes, including an AI-powered adaptive setting that automatically adjusts the level of noise cancellation based on your surroundings. This ensures you always have the optimal level of quiet without having to constantly fiddle with settings. The dedicated Wind Noise Cancelling mode is also incredibly effective, making outdoor calls and listening on breezy days a pleasure.
-
Functional Ambient Sound: When you need to be aware of your surroundings, the Ambient Sound mode works wonderfully. It uses the external microphones to pass through environmental sounds with clarity, allowing you to have a quick conversation or listen for announcements without ever needing to remove the earbuds. It’s a critical feature for safety and convenience that is executed perfectly here.
Call Quality and Connectivity
Equipped with a triple microphone array and the latest in wireless technology, the Air Pro 4 is a communication and connectivity powerhouse.
​
-
Voice Calls: Each earbud contains three microphones, creating an advanced 6-microphone array that works in concert with Qualcomm’s cVc™ 8.0 noise suppression technology. This system is engineered to isolate your voice and eliminate distracting background noise. During our daily calls and video conferences, our voices came through with clarity and volume, even when we were in moderately noisy environments like a busy coffee shop. Although the mic quality would not be as good as the mic quality on a more expensive earbud, the Air Pro 4's mic is excellent for being a budget earbud.
-
Next-Gen Bluetooth 5.4: The inclusion of Bluetooth 5.4 provides a rock-solid, incredibly stable connection with enhanced range and efficiency. When we tested and paired it with Apple and Android products, the pairing was instantaneous and dropouts were virtually nonexistent. This modern standard is the backbone that ensures a seamless and reliable experience for both music and calls.
-
Future-Proof Technology: These earbuds are not just built for today; they are ready for tomorrow. With hardware support for the next generation of Bluetooth audio, LE Audio and its revolutionary Auracast™ broadcast feature, the Air Pro 4 is a smart investment that is protected against technological obsolescence. This forward-looking approach is a massive advantage.
-
Multi-Device Connectivity: A key convenience feature for modern workflows is the ability to connect to two devices simultaneously. We seamlessly switched between a laptop for a video call and a smartphone to listen to music without ever having to re-pair the earbuds. It’s a fluid, intuitive feature that just works.
Battery Life and Charging
The battery performance of the EarFun Air Pro 4 is, in a word, exceptional, liberating you from the constant anxiety of searching for a power outlet.
-
Class-Leading Stamina: The battery life is simply phenomenal and stands head-and-shoulders above the competition. With ANC turned off, you can get up to an incredible 11 hours of playtime on a single charge. The charging case extends this to a staggering 52 hours of total listening time! This is true all-week power. Even with ANC on, we were easily averaging over 7 hours of continuous use.
-
Versatile Charging Options: EarFun has included every charging convenience you could want. A quick 10-minute charge via the USB-C port provides a full 2 hours of playback, which is perfect for a last-minute power-up.
-
The Convenience of Wireless: The addition of Qi-compatible wireless charging is a premium feature that cements these earbuds as the king of convenience. Simply dropping the case onto a wireless charging pad at the end of the day is an effortless experience that you’ll quickly find indispensable.
Controls and Software
The EarFun Air Pro 4 provides a deeply customizable and powerful user experience through its responsive touch controls and feature-packed companion app.
-
Comprehensive Touch Controls: The capacitive touch panels on each earbud give you full command over your media and calls. You can control playback, adjust volume, navigate tracks, and cycle through noise control modes with simple taps and presses.
-
Complete Customization: The EarFun Audio app puts you in the driver’s seat. It allows for full customization of the touch controls, so you can reassign functions to perfectly match your personal workflow. For those who worry about accidental touches, the ability to disable the single-tap gesture is a thoughtful and incredibly welcome solution that we took full advantage of during our testing.
-
A Powerful Command Center: The app is far more than just a settings menu; it’s a powerful command center for your earbuds. It’s where you’ll find the game-changing 10-band equalizer, access all the ANC modes, monitor battery levels for each component, toggle the low-latency Game Mode, and receive firmware updates that continue to add features and refine the experience.
Conclusion: Best Budget Pick!
The EarFun Air Pro 4 is a triumph of engineering and fantastic value. It’s not just great for its price, it’s a genuinely great product that competes with and surpasses devices from some established flagship brands.
