The EarFun Air Pro 4+ are budget-friendly noise cancelling earbuds with an unusually feature-packed design for their price. They support extras like LDAC and LC3 codecs, adjustable ANC, a customizable companion app, dual-device pairing, and even an AI translation feature, which helps them stand out from a lot of cheaper truly wireless options.
Our Verdict
The EarFun Air Pro 4 Plus are very good for sports and fitness. They're very light, portable, and mostly stay in your ears when you move around. With an IP55 rating, they'll also survive a run in the rain. That said, they can come loose over time and don't have ear-hooks, so they're best suited to more casual workouts. They also may not suit people with very small ears, who might find it hard to get a snug seal.
Excellent at blocking out office and street noise.
Feature-rich app.
Wide Bluetooth codec support.
Fit can loosen over time, compromising ANC and sound.
Case lid and hinge feel a bit weak.
The EarFun Air Pro 4 Plus are very good for travel. Their ANC system does an impressive job blocking out noise, and performs especially well isolating you from real-world noise like the sounds of a busy street or bus. They're comfortable enough for day-to-day commuting, and also come with a protective case that's small enough to slip easily into a pocket or bag. That said, their battery life is roughly 4.5 hours with ANC on, so they're not a good choice for longer travel like flights.

The EarFun Air Pro 4+ earbuds are decent for office work. They block out office chatter very well, and they don't leak much audio, so coworkers nearby should only hear a thin version of your audio, even at louder volumes. They also have a warm, versatile sound profile that suits most kinds of audio content, as well as a light in-ear fit. However, their mic makes your voice sound dull and thin.

The EarFun Air Pro 4 Plus aren't a good choice for wireless gaming as they do not have a wireless dongle. Even via their lowest latency Bluetooth connection, latency is also too high for serious gaming.
The EarFun Air Pro 4 Plus can't be used wired.
The EarFun Air Pro 4 Plus have good audio reproduction accuracy. Their default sound is warm, with extra bass that adds thump and punch to kick drums, while the mid-range stays remarkably accurate, so vocals and instruments sound natural and detailed. Their response doesn't deviate much from this warm sound signature, apart from a few peaks and dips in the treble range that are hard to hear. They have very impressively well-matched left and right drivers, so you can generally expect objects to be accurately located in the stereo field.
The EarFun Air Pro 4+ ANC have impressive noise isolation. Their ANC is most effective against mid-range sounds like nearby conversations, and they do an especially good job with real-world office and street noise once the system has adjusted to the environment. They aren't as good at blocking out sounds like bass-heavy engine rumble, though. On the plus side, they also leak very little sound, and the companion app includes a wind reduction mode to help in breezy conditions.
The EarFun Air Pro 4 Plus have an unremarkable microphone. If you're taking a call from a quiet room, your voice stays understandable because the mid-range is reproduced reasonably well, but you'll sound a bit dull and thin. That said, the mic system doesn't fare well in noisier environments. These earbuds are fine for occasional calls in quieter places, but they aren't a strong choice if you regularly take calls while out and about in the world.
The EarFun Air Pro 4 Plus have fantastic frequency response consistency. If you get a good seal with the included silicone tips, they should sound very consistent from one wear to the next. However, it's worth noting that the fit could loosen over time, so it's worth taking a moment to seat them properly each time you insert them.

Popular Headphones Comparisons
The EarFun Air Pro 4+ are one of the more fully featured product in EarFun's Air Pro lineup to date. Unlike older entries like the original EarFun Air Pro and EarFun Air Pro 2, which lacked proper app-based sound customization, the Pro 4+ mimic the EarFun Air Pro 3 in offering a companion app with an EQ, along with support for a wide variety of Bluetooth codecs. The main improvement of the Pro 4+ over the Pro 3 is the sound profile, which is much more controlled and easier to EQ.
That said, when looking at the broader market of affordable wireless earbuds, the Anker Soundcore Space A40 Truly Wireless are still the safest pick for most people because of their superior battery life and ANC performance. And if you prefer a stem design or want affordable earbuds you can use for calls, the CMF Buds Pro 2 are the way to go. The Pro 4+ make the most sense if you specifically want a stemmed budget earbud with a broad suite of Bluetooth codecs. Otherwise, the EarFun fall a little short of the competition.

The EarFun Air Pro 4+ and the Anker Soundcore Liberty 4 NC Truly Wireless are both feature-rich budget ANC earbuds that share a stemmed design. In truth, they're neck and neck in almost all performance metrics bar one: battery life. The Anker last about twice as long as the EarFun on a single charge, so they're the obvious pick for most people. We'd only recommend the EarFun over the Anker if you know you want access to Bluetooth codecs like aptX adaptive.
The EarFun Air Pro 4+ and SoundPeats H3 are Bluetooth earbuds that trade blows in many performance metrics. The SoundPeats have better ANC and noise isolation, but their battery lasts for less time (3.5 hours vs. the EarFun's 4.75). The EarFun's app is more polished, with fewer bugs and connection issues, though their mic system isn't as good at isolating your voice from noise compared to the SoundPeats. Both earbuds are also targeted towards a similar price segment, so the winner will come down to which checks more boxes for you.
The EarFun Air Pro 4+ and the Nothing Ear are similarly priced noise cancelling earbuds with stemmed designs, but they suit slightly different priorities. The EarFun are the better pick if you care most about ANC performance, especially for day-to-day street and office noise, and they also offer a broader Bluetooth codec selection, including LC3 and aptX Adaptive. That said, the Nothing Ear come out ahead in a few important everyday areas. They have a noticeably longer continuous battery life and a better microphone system for calls in noisy places.
The EarFun Air Pro 4+ and the CMF Buds Pro 2 are both feature-packed budget ANC earbuds, but they have different strengths. The EarFun have a more balanced sound out of the box, and they also offer support for a wider range of Bluetooth codecs. On the other hand, the CMF have a longer battery life and a slightly better microphone. Both isolate noise well, so the choice mostly comes down to whether you'd rather have the EarFun's more versatile stock tuning and Bluetooth feature set or the CMF's longer-lasting battery with a superior mic.
