Earfun Air Pro 4 Plus: Two-minute review
I’ve tested quite a few pairs of Earfun earbuds before, but before I’d even had a chance to get the new Earfun Air Pro 4 Plus into my shell-likes, I’d already seen countless rave reviews of them from other websites. Suffice to say, the press at large finally discovered Earfun (not just audio-savvy types like me) and their impressions are glowing.
I can’t pretend to have reviewed every Earfun proposition – the budget brand puts out far more products than any one person could hope to review – but I’ve used multiple of its in-ears and over-ears, and some of them have made it into TechRadar’s list of the best cheap headphones we (and I) have tested.
So what about the Earfun Air Pro 4 Plus, so good that Earfun had to name it four times (then add a ‘Plus’ moniker, to make things a bit more confusing)? They’re – drumroll please – absolutely fine. More of the cheap-and-cheerful same that I’ve come to expect from the brand, but with a few rough edges that mean they’re not the best earbuds I’ve ever used. No, not even at this low price.
The ‘Plus’ presumably signifies a more advanced model of the Earfun Air Pro 4 I tested in late 2024, although with more titles than a character from Downton Abbey it’s hard to be sure. Those were decent and cheap headphones with a few too many EQ modes for their own good and a lack of refinement in the audio department, and the Plus has added a few things – but not fixed any of those issues.
As with other buds from the brand, my favorite thing about the Air Pro 4 Plus is the stand-out feature list, which rivals alternatives that’d cost you twice as much. There’s a stellar battery life, a listening test, dual-device connectivity and multiple other options. When you put some Earfuns in, the ball’s in your court.
The things is, loads of features can also become a problem – there are six different ANC modes (counting ‘off’, I’ll admit), one of which has its own slider. How to tell which mode you should be using at any one time is anyone’s guess (unless you want it ‘off’, which is a pretty easy pick).
The buds are nice and lightweight, surviving long listening periods as well as gym workouts and runs well, and the case is pretty svelte too. These are solid picks for your commute or while you’re sitting in the office.
If you’re an audiophile, though, these won’t tick your boxes; they’re not the best buds in terms of sound, even for their price. I’ll get to some better-sounding options below, but the feature set makes a great case for why you should consider buying these anyway.
Earfun Air Pro 4 Plus review: Price and release date
- Released on September 26, 2025
- Costs $99.99 / £89.99 (around AU$280)
- Slight price increase over non-Plus model
The Earfun Air Pro 4 Plus – I’m going to get really sick of writing that whole title out across this review, I can tell – were released on September 26, 2025, and could be bought on that day.
The official price of the earbuds is $99.99 / £89.99 (around AU$180) . Amazon lists those costs as the discounted price, and $119.99 / £109.99 (around AU$220) as the original price, but as far as I can tell they’ve never been sold for that higher price, making it look like a bit of an underhanded method to present the usual price as discounted. On Earfun’s website, the cheaper price is presented as the normal one, and so I’m taking that as my guide price for the purposes of context and comparison.
That price puts them as a hair pricier than the $89.99 / £79.99 (roughly AU$140) Air Pro 4, and roughly the same as the Air Pro 3. They’re among the priciest buds for Earfun but that’s not saying much, as the brand specializes in affordable audio.
At that cost, I’d still call the Air Pro 4 Plus ‘cheap earbuds’, although they’re toeing the border and bumping up against some real heavyweight rivals in the triple-figure-price-tag camp.

Earfun Air Pro 4 Plus review: Features
- 8-hour buds battery, 54-hour with case
- Confusing ANC modes
- Loads of handy features in app
I love a meaty battery life in earbuds, and Earfun clearly concurs. With 54 hours of listening time in the tank, you’re not going to need to worry about powering the buds daily (or even weekly, depending on your listening habits).
That’s the figure for the case, and the buds themselves last 12 hours if you’re listening with ANC turned off or 8 hours if it’s turned on. Both are great figures, slightly better than on the non-Plus model, that’ll assuage any battery anxiety you might have.
You get a few extra features with Earfun Audio, the tie-in smartphone app. You can toggle wear detection, customize the buds’ touch controls, choose which Bluetooth codecs are in use, change some microphone settings, find your headphones if you’ve misplaced them, and set up dual device connection.
I’m always surprised by the number of features Earfun offers in its earbuds, with many premium alternatives having half as many. Sometimes that gets a little overwhelming though, like in the case of noise cancellation. Not counting ‘off’ or a useful Ambient mode, there are four different modes: Ear Adaptive, Environment Adaptive, Wind and Manual Adaptive (which lets you use a slider to choose its intensity).
Even after having read the descriptions multiple times, and having used other Earfun products with these modes, I can’t tell the difference between Ear and Environment, or Environment and Wind, and have no idea how to choose which of these modes to use. Even if I could work out the use case for each mode, there’s no way you’re going to catch me going into the app to change modes every time the wind picks up a little bit.
The app offers an equalizer with myriad presets, a ten-band custom mode or a sound profile test to create a personalized mix. This latter isn’t quite as accurate as rival modes, but generally speaking you have to spend a lot more money on alternatives with listening tests, so it’s a welcome presence in this budget option.
Through the entire testing process, I never once had any Bluetooth drop-out issues with the buds, and it was reliably quick to pair. You can probably thank the use of Bluetooth 6 for this, which is a much more advanced version of wireless connection than most rival buds have.
Earfun Air Pro 4 Plus review: Design
- Understated purple hue
- Lightweight case and buds
- IPX5 rating
It’s in the name: the ‘Air’ part of Earfun Air Pro 4 Plus describes the case. It’s lovely and light, weighing 54g, and the ‘clamshell’ style of opening means it’s easy enough to open and remove the buds. No fiddling involved.
Now onto the buds; they’re nice and lightweight too, hitting the scales at about 6g, although they seem a little bit bigger than the non-Plus models (at least, based on my recollection, and I’m sure a justification will be clear when we get to the sound quality section).
The Earfun Air Pro 4 Plus are stem-style buds, with the earbuds attached to your ear via a tip, and a stem dangling down, just like AirPods.
Each bud has a touch control, which you can trigger by tapping the circle at the top of the stem. I found them easy to press, albeit a little too sensitive when I was readjusting the buds in my ears.
The buds have an IP55 rating, which means they’re protected against limited dust ingress and jets of water. This latter means they’re not suitable for water submersion, so don’t take them for a swim. One of the benefits of a plastic build material ensures that the buds are hardy against drops and knocks.
I took the Earfuns to the gym a few times and they never fell out, and while they felt a little loose when they accompanied me on a run, they never actually did fall out. This was with the default tips, but the box comes with a few alternatives to account for various ear sizes. They were comfy to wear too, and I didn’t face any aches or strains after extended listening periods.
Earfun Air Pro 4 Plus review: Sound quality
- BA driver + 10mm dynamic driver
- Range of codecs supported
- Treble and mids still miss some pizzazz
Perhaps the biggest advances the Earfun Air Pro 4 Plus brings over its siblings – and other cheap buds – is in the audio specs department.
There are two drivers: a 10mm composite dynamic driver which handles the bass and midrange, alongside a balanced armature driver which focuses on providing high-frequency response and high audio detail.
If that wasn’t enough, the Earfun supports a range of audio codecs and features that you’d expect from pricey buds: LDAC, aptX Lossless, aptX Adaptive Snapdragon Sound and Hi-Res Audio Wireless Certification to be precise.
The spec improvements certainly bring some benefits over past Earfun buds I’ve tested, with well-defined bass and a slightly more pronounced sound stage, but the augments don’t do enough to make these sonic equals to some of the other budget buds on the market.
Treble remains somewhat dampened, with vocals missing that sparkly energy and depth that you’d want from a song, and mids still hopelessly lost in the mix. As I mentioned before, the bass improvements ensure it’s tactfully-tuned, and doesn’t drown out other parts of a song as much as in the non-Plus pair, but that also makes these buds less tempting for bass-heads.
Using the equalizer, you can pull out some strings to improve the sound – I liked Vocal Enhancement which added some force to the sung word and expanded the sound stage, but it increased the risk of peaking on certain instruments and made sibilant lines sound tinny. For certain other sounds I went for Bass Boost 1, which doesn’t send the bass into overdrive as you’d expect, but adds clarity and dimension to low-frequency lines. As a bass player myself, it got surprisingly close to replicating the sound of actually playing a bass guitar.
I don’t want to be too down on the Air Pro 4 Plus – it sounds perfectly fine, and I don’t imagine many people will be disappointed by how it sounds. But as someone that’s tested plenty of rivals, I’d be remiss not to point out that it’s not the top dog.
Earfun Air Pro 4 Plus review: Value
- Feature set is great for price
- Audio quality is more what you’d expect
As with its many past earbuds, Earfun has packed a great number of features and some impressive specs into a relatively low-cost set of buds.
Perhaps not all of those features are as fleshed-out as they would be on a pricier pair of buds, but their very presence in the first place is great for people who don’t want to pay more.
My only caveat would be that you could get even more bang for your buck by buying one of Earfun’s other, cheaper options.

How I tested the Earfun Air Pro 4 Plus
- Tested for 2 weeks
- Tested at home, on walks, and the gym and on runss
I used the Earfun Air Pro 4 Plus for about two weeks to write this review, which is about enough time to write that entire name.
During the test process, the buds were mostly paired to my Android smartphone. I used them in a wide variety of environments including at home, at the gym, on walks around my borough, on runs and to the shops. I played games, listened to Spotify, Tidal and Qobuz and watched YouTube videos as the main ways to test, but used them as my daily blowers too, so there are a plethora of other tasks I used them for.
As mentioned in the introduction, I saw quite a bit of coverage on the Earfun before writing my review, however I never read into reviews beyond the positive headlines in order to avoid their biasing my opinions.
Also as mentioned, I’ve used other Earfun earbuds in the past, as well as plenty of other cheap alternatives in my six-plus years testing tech for TechRadar.
