The EarFun Air Pro 4 proves you don't have to spend hundreds of dollars to get premium wireless earbuds. Priced well under flagship models from Apple, Sony, and Bose, the Air Pro 4 packs in features like Active Noise Cancellation (ANC), high-resolution audio support, multipoint Bluetooth, wireless charging, and impressive battery life.
On paper, it's one of the most feature-packed earbuds in its price range. But does its real-world performance live up to the hype? More importantly, is the fit secure enough to enjoy everything these earbuds have to offer?
Let's take a closer look.
Overview
The EarFun Air Pro 4 is one of the best value true wireless earbuds on the market. It combines balanced sound, effective Active Noise Cancellation, long battery life, and premium features at a fraction of the price of many flagship competitors.
In this review, we'll cover its design, comfort, sound quality, ANC performance, battery life, and whether the fit is secure enough for everyday use.
Design and Comfort
The EarFun Air Pro 4 features a sleek stem-style design that feels modern without trying to imitate premium competitors too closely. The earbuds are lightweight and compact, making them comfortable enough for extended listening sessions.
EarFun includes multiple silicone ear tip sizes, allowing most users to find a comfortable fit. Once inserted correctly, the earbuds sit securely for everyday activities like commuting, working, traveling, or relaxing at home.
For light exercise and walking, the Air Pro 4 generally stays in place well. However, users with smaller ears or those participating in higher-impact activities may occasionally need to readjust the earbuds.
As with nearly every in-ear earbud, comfort and stability depend largely on achieving a proper seal.
Sound Quality
One of the Air Pro 4's biggest strengths is its sound quality.
The earbuds deliver a lively, balanced sound signature with punchy bass, detailed mids, and crisp highs that work well across a variety of music genres. Bass has enough impact for pop, hip-hop, and electronic music without overpowering vocals or instruments.
Vocals remain clear and natural, while guitars, keyboards, and percussion retain good separation. Although the Air Pro 4 may not match the expansive soundstage of premium audiophile earbuds, it performs remarkably well for its price point.
Support for high-resolution codecs also gives compatible devices access to improved wireless audio quality, making these earbuds appealing to listeners who want more than basic Bluetooth performance.
Overall, the EarFun Air Pro 4 offers sound quality that competes with earbuds costing significantly more.
Active Noise Cancellation
Active Noise Cancellation is another area where the Air Pro 4 exceeds expectations.
The earbuds do a solid job reducing common background noises like air conditioners, office chatter, traffic, and airplane cabin noise. While they don't completely eliminate distractions, they create a quieter listening environment that makes music and podcasts easier to enjoy.
Transparency Mode is equally useful, allowing outside sounds to pass through naturally when you need to hear announcements or have conversations without removing your earbuds.
For most users, the ANC performance will feel surprisingly capable considering the price.
Battery Life and Features
Battery life is another standout feature.
The EarFun Air Pro 4 offers several hours of playback on a single charge, with the charging case providing multiple additional charges for extended listening throughout the week.
Other premium features include:
- Active Noise Cancellation
- Transparency Mode
- Bluetooth Multipoint
- Wireless Charging
- Fast Charging
- High-Resolution Audio Support
- Wear Detection
- Custom EQ through the EarFun app
- IPX5 Water Resistance
It's a feature list that rivals many earbuds costing considerably more.
The Biggest Question: Is the Fit Secure?
For many buyers, fit is just as important as sound quality.
The Air Pro 4 performs best when it maintains a secure seal inside your ears. A proper fit not only keeps the earbuds comfortably in place but also helps maximize bass response, improve noise isolation, and allow ANC to perform at its best.
For everyday listening, the earbuds generally stay secure during commuting, office work, and casual movement.
However, during running, gym workouts, or higher-impact activities, some users may notice the earbuds gradually loosening. This is common with many stem-style earbuds and often comes down to ear shape rather than the earbuds themselves.
If the seal breaks, you may notice:
- Reduced bass response
- Less effective ANC
- More outside noise
- Audio that sounds less immersive
- Frequent readjustments
Because so much of the Air Pro 4's performance depends on maintaining a proper seal, achieving the right fit can make a noticeable difference in your overall listening experience.
Looking for a More Secure Fit?
If you've tried different ear tip sizes and your EarFun Air Pro 4 still doesn't feel completely secure, the ear tips themselves may be the issue.
Comply Memory Foam Ear Tips are designed to conform to the unique shape of your ear canal, creating a personalized fit that helps improve stability, comfort, and passive noise isolation. Unlike standard silicone tips, memory foam expands to create a more consistent seal, helping your earbuds stay comfortably in place throughout the day.
A secure fit can also improve bass response and allow your ANC to perform more effectively, helping you get the most from your EarFun Air Pro 4.
Should You Buy the EarFun Air Pro 4?
The EarFun Air Pro 4 is one of the easiest wireless earbuds to recommend for buyers looking for premium features without paying a premium price.
You should consider the Air Pro 4 if:
- You want excellent value for your money.
