Earfun has once again delivered exceptional value with its latest earbuds, the Air Pro 4 Plus. Building on the success of last year’s Editor’s Choice-winning Air Pro 4, these new earbuds offer significantly improved sound quality for around $80—a mere $20 more than the previous model. While not flawless, the Air Pro 4 Plus represent a compelling upgrade for anyone seeking high-fidelity audio without breaking the bank.
Enhanced Audio Performance: A Worthwhile Step Up
The most notable improvement in the Air Pro 4 Plus lies in their dual-driver system. Pairing a 10mm dynamic driver with a balanced-armature driver, these earbuds deliver richer, more detailed sound than their predecessor. While the Air Pro 4 offered solid performance for their price, the Plus model boasts superior bass definition and smoother, more vibrant treble. This enhanced clarity makes them stand out in a crowded market, even revealing flaws in poorly mastered tracks—a testament to their accuracy.
This level of audio fidelity is rare at this price point. Competitors like Samsung’s Galaxy Buds 3 Pro offer slightly better sound but cost twice as much. The Earfun Air Pro 4 Plus effectively bridge the gap between budget-friendly and premium earbuds.
Design and Comfort: Familiar Yet Refined
Visually, the Air Pro 4 Plus closely resemble the Air Pro 4, with a slightly larger profile. The real change is in the charging case: while the Air Pro 4 used a clamshell design, the Plus model features a flip-up, vertical case—a minor but welcome upgrade in convenience. Both cases support wireless charging.
The earbuds themselves remain lightweight at 5.2 grams each and provide a secure, comfortable fit. They also boast an IP55 rating for splash and dust resistance, an improvement over the Air Pro 4. Customizable touch controls and ear-detection sensors add further convenience.
Features and Battery Life: A Robust Package
The Air Pro 4 Plus include a comprehensive feature set, including Bluetooth 6.0, Qualcomm’s QCC3091 SoC, and QuietSmart 3.0 Adaptive Hybrid Active Noise Cancellation (ANC) that reaches up to 50dB. They also support AptX Lossless and LDAC codecs for Android devices, as well as a low-latency gaming mode.
Battery life remains competitive, offering up to 8 hours of playback with ANC enabled and a total of 54 hours with the charging case. This is comparable to Apple’s AirPods Pro and exceeds the battery life of many competitors.
Areas for Improvement: Voice Calling and Software Stability
Despite their strengths, the Air Pro 4 Plus aren’t perfect. Voice-calling performance, while decent in quiet environments, struggles in noisy conditions. Callers reported difficulty hearing clear audio in windy outdoor settings. Additionally, the companion app occasionally disconnects from the earbuds, particularly with iOS devices. While Earfun can likely address these issues through firmware updates, they currently prevent the Air Pro 4 Plus from achieving true perfection.
The Verdict: An Exceptional Value Proposition
The Earfun Air Pro 4 Plus are an outstanding choice for anyone prioritizing sound quality without exceeding a $100 budget. They deliver a compelling combination of premium features, improved audio fidelity, and solid battery life. While voice-calling and software stability could use refinement, these minor shortcomings are easily outweighed by the overall value. For those seeking high-performance earbuds without the exorbitant price tag, the Air Pro 4 Plus are an easy recommendation.
