EarFun Air Pro 4 sits in the feature-heavy value segment of true-wireless earbuds. The useful way to review it is not by counting logos on the box, but by checking which features your phone actually supports and whether the fit works for your ears.
Focus on five things: secure seal, ANC behavior, Bluetooth stability, codec compatibility and battery life in the modes you use. A codec or ANC label alone does not predict how the earbuds will sound to you.
What to Check on Air Pro 4
| Area | Why it matters | How to evaluate |
|---|---|---|
| Fit and seal | Affects bass, isolation and ANC | Try multiple tip sizes and confirm both earbuds seal consistently |
| ANC | Most useful against steady travel and HVAC noise | Compare with ANC off in the same environment |
| Bluetooth/codecs | Features vary by phone and operating system | Confirm what your source device supports before prioritizing a codec |
| Battery | ANC, volume and codecs change runtime | Compare manufacturer test conditions with your typical use |
Feature Lists Need Device Context
Modern EarFun models support a broad set of wireless features, but Android and iPhone users do not always get the same codec options. Multipoint, low-latency modes and app settings can also interact. Before buying for a specific feature, check EarFun's current Air Pro 4 product page and your phone's Bluetooth capabilities.
Fit Comes Before Tuning
A poor seal can make bass sound weak and reduce passive isolation, which also makes ANC seem less effective. If one ear sounds different from the other, reseat the earbud and try another tip size before changing EQ.
Call Quality Depends on the Room
Microphone arrays and noise reduction can improve calls, but wind, traffic and keyboard noise are difficult conditions. If calls are a priority, compare samples recorded in the type of environment you use rather than relying on microphone count.

Frequently Asked Questions
Is EarFun Air Pro 4 only for Android?
No. It works with supported Bluetooth devices, but some advanced codec options depend on the source platform.
Does better codec support guarantee better sound?
No. Driver tuning, fit, recording quality, volume and your hearing matter as well. Codec support is one part of the chain.
How should I judge battery life?
Compare the manufacturer's test mode with your real use. ANC, higher volume, calls and some processing features can shorten runtime.
