EarFun Air Pro 4 Review – Big Features at a Smaller Price
If you’re hunting for true wireless earbuds that punch above their weight in features without breaking the bank, the EarFun Air Pro 4 are very compelling. With support for hi-res codecs (LDAC, aptX), the latest Bluetooth standard (5.4), robust multipoint connectivity, and serious active noise cancellation (ANC), they make a strong case for both everyday listeners and tech-aware users. I’ve spent the past week juggling phone calls, streaming, commuting noise and editing–here’s how they hold up in real-world use.

Design, Fit & Build
Visually the Air Pro 4 follow a stemmed TWS design, similar to many others, but with “premium-budget” finishes and good ergonomics. According to reviews, they weigh about 5.5 g per earbud and include multiple tip-sizes to optimise fit. (headphonecheck.com)
Fit is solid for most sessions including walks or light workouts, though a few reviewers noted that the ear tip shape and insertion depth may take adjustment. (Scarbir)
Build quality is again strong for the price point: the case supports wireless charging, the earbuds have decent splash resistance (IPX5 in some tests) and the tactile feel is good. (headphonecheck.com)
Verdict on build/fit: Very good in context. If you want ultra-rugged field gear, there are more premium choices — but for everyday carry this is excellent.
Active Noise Cancellation & Connectivity
One of the standout features of the Air Pro 4 is their ANC system. According to Major HiFi and other reviewers, the buds use a series of microphones and AI-driven noise reduction to deliver very strong (for their class) isolation. (Major HiFi)
For example, HeadphoneCheck reports multiple ANC modes (strong, balanced, adaptive) and claims up to ~6 hours earbuds alone with ANC on in certain tests. (headphonecheck.com)
On the connectivity front: Bluetooth 5.4, LE Audio support/LC3 in compatible devices, full support for LDAC & aptX (including Lossless in some contexts) and multipoint are all present. (headphonecheck.com)
For smart-home/connected device usage, this means you can switch between laptop and phone without re-pairing, enjoy higher codec fidelity (if your source supports it), and future-proof a bit.
Verdict on ANC & connectivity: Excellent value. If you depend on seamless switching between devices or high-res streams, this is a place where the Air Pro 4 really shine in their tier.

Audio Quality & Codec Support
Here the Air Pro 4 also deliver strong results. SoundGuys calls them “worthy purchase for pretty much anyone seeking budget earbuds.” (SoundGuys)
In listening tests:
- Bass: They deliver satisfying punch and energy. Several reviewers highlight a more bass-forward signature but still good separation. (Aaron x Loud and Wireless)
- Mids & vocals: Clear, though some note that in very dense mixes the soundstage isn’t as wide or “airy” as ultra-premium models.
- Highs & detail: Good clarity. With LDAC enabled and good seal you’ll hear more micro-details than typical budget buds.
Codec support: LDAC (Hi-Res), aptX Adaptive/Lossless, AAC/SBC — rare in this price band. However: enabling LDAC sometimes limits multipoint or other features (typical trade-off) as many reviewers point out. (Aaron x Loud and Wireless)
Verdict on audio: Very strong for the price. For audiophile purists there are better options, but for the majority of listeners this delivers excellent value and sound.
Battery Life & Smart Features
According to tests from HeadphoneCheck: around 11 hours earbud playback (with ANC off) in some conditions, about 6 hours with ANC on; total with case up to ~35 hours in ANC mode. (headphonecheck.com)
Other sources report even higher numbers (~52 hours total) depending on settings. (Android Central)
Smart features: companion app allows parametric EQ, many presets, touch control customisation, game mode (lower latency) and multipoint switching. (Major HiFi)
Verdict on battery / features: Strong. Not quite at ultra-flagship endurance, but absolutely competitive given the price. The app and codec features give them an edge in the “smart earbuds” segment.

What Could Be Better
- Multipoint + hi-res codec trade-off: some users note you cannot have LDAC + multipoint simultaneously. (Aaron x Loud and Wireless)
- Transparency/ambient mode: one reviewer noted the passthrough experience was less seamless until a firmware update. (Aaron x Loud and Wireless)
- Fit & ear tip comfort: for users with non-standard ear shapes, the larger tip set may cause fatigue after long sessions. (Scarbir)
- IP rating is good (IPX5) but not up to full “rugged/outdoor” extreme weather standards.
Final Verdict
As someone focused on ecosystem integration and smart features, I can say the EarFun Air Pro 4 hit a sweet spot: they bring flagship-adjacent features (hi-res codecs, ANC, multipoint) at a budget tier. If you’re using them with an Android device that supports LDAC and need top-tier connectivity between phone and laptop, these make a lot of sense.
