EarFun Air Pro 4 Earphones Review: Affordable Excellence

The budget-priced true wireless earphones market is as competitive as ever these days – and one of my favourite companies in that arena is back with an updated version of their popular Air Pro line.

The EarFun Air Pro 4 earphones take everything that was great about the previous model – and crank it up a notch. The sound quality remains excellent (with some tweaks available for us bass-heads), the Active Noise Cancelling is even better this time around (but don’t expect it to be perfect), and the battery life has been pushed to new heights.

So what’s new? We’ve got more codec options, the return of in-ear detection, and a host of customization features via the app (maybe even a bit too many).

Taking everything into account – are these the right earphones for you – and are they a worthy upgrade to the Air Pro 3? The short answer is yes – for most people. But as always, there are a few caveats. Read on for the full lowdown…

Who Are The EarFun Air Pro 4 For?

Having used EarFun’s earphones for several years now (they’ve been around since 2018), I can safely say they’re still at the top of their game in the mid-range true wireless market – and the new Air Pro 4 is solid proof of that.

The very first EarFun Air Pro model showed promise but was lacking in several areas. Then came the Air Pro 2, which quickly became one of my favourite true wireless models.

The Air Pro 3 built on that success, and now we have the Air Pro 4 – and while this isn’t a revolutionary upgrade, it certainly improves on many aspects that made its predecessors great.

For starters, the sound quality is excellent. Out of the box, it might feel a bit flat for deep bass fans like me, but a quick tweak of the equalizer in the app fixed that.

The Active Noise Cancelling levels are even better than before – great for your daily commute or those noisy open-plan offices (but certainly not perfect).

And as usual, the greatest trick EarFun pulls here is the price – for a suggested retail price of £79.99, which often comes down thanks to discounts, these certainly hit above their weight class.

If you’re after top-notch sound, effective noise cancellation, and a long list of premium features without the premium price tag, the Air Pro 4 might just be your perfect match.

Using The EarFun Air Pro 4

Size And Comfort

The ‘Air’ moniker is still in the name, and the stem-style design reminiscent of Apple’s AirPods remains – but this time around, they’ve managed to look even better, thanks in part to a glossy finish that gives them a more premium feel.

Yes, they’re still predominantly plastic – including the case – but the overall aesthetic has taken a step up.

The earbuds themselves are slightly heavier than the Air Pro 3, but this increase comes with a silver lining: improved battery life.

Despite the minor weight bump, I found the Air Pro 4 to be impressively comfortable. They nestle snugly in the ear, and I’ve had no issues wearing them for several hours at a time.

In the box, you now get five ear tip sizes in total – that’s one more than what came with the Air Pro 3. This extra option should make it even easier for most people to find their perfect fit, and the in-ear seal feels even better this time around, which helps with noise cancellation.

You also get the usual suspects: a USB-C charging cable and the charging case, which continues to support wireless charging for added convenience.

As before, the earphones boast an IPX5 water and sweat resistance rating. This means they’re perfectly suitable for rainy days or sweaty workouts, but you’ll want to avoid submerging them in water.

And, as always, remember that the charging case isn’t water-resistant, so keep it safe and dry when you’re out and about.

Pairing And Controlling The EarFun Air Pro 4

Pairing the Air Pro 4 with your phone (or other devices) is as seamless as ever – they immediately go into pairing mode when you first open the case. This time around, there’s an added bonus for Android users: Google Fast Pair support. This makes the initial setup even quicker, getting you up and running with minimal fuss.

Once paired, reconnecting to the same device is almost instant – something I particularly appreciate when I get incoming phone calls.

Thanks in part to the upgraded Bluetooth 5.4, the Air Pro 4 maintains a rock-solid connection. In my weeks of testing, I never encountered sudden disconnections or Bluetooth hiccups, even in crowded areas that typically wreak havoc on wireless signals.

Controlling the earphones remains intuitive, with the touch surface striking a good balance between responsiveness and avoiding accidental inputs.

The usual array of taps and long-presses are available to control volume, playback, and switch between ANC modes. As before, you can customise these controls via the EarFun app to suit your preferences.

Speaking of the app, it’s a tweaker’s dream come true: you switch ANC modes (more on that below), customise the controls, enable or disable almost every feature and fine-tune the EQ.

It might be overkill for some, but other than for important firmware updates (there have already been two during my time with the earbuds), you don’t HAVE to change anything in the app if you don’t want to mess with things too much.

And – there’s even a ‘Find Your Earphones’ feature on the app – which can make the earbuds beep when they get lost under your sofa cushions.

One welcome return is the in-ear detection feature, which was mysteriously absent on the Air Pro 3. Now, if you pull one (or both) of the earbuds out of your ears, your music automatically pauses. Pop them back in, and the tunes resume. It’s a small touch but one that adds to the overall polished feel of these earphones.

EarFun Air Pro 4 Audio Quality

When it comes to audio codecs, the Air Pro 4 is packed to the gills with options.

There’s support for aptX Lossless, aptX Adaptive, LDAC, AAC, and SBC. Of course, your mileage may vary depending on your device – iPhone users, for instance, will be limited to AAC. But for Android users with compatible phones, these earbuds offer a long list of high-quality audio options.

For testing purposes, I first queued up Toto’s Africa.

This 80s classic gave the Air Pro 4 a real workout, and I was pleasantly surprised by the results. The earphones offered a surprisingly immersive experience with crisp highs and balanced mids that let the iconic melody shine.

The bass provided a solid foundation without overwhelming the track. Overall, it was a solid listening experience that captured the essence of this classic hit.

Jumping to something more contemporary, I gave Nick Jonas’ Close a spin.

The track came alive with vibrant clarity and punchy bass (along with my Bass Boost tweak), with detailed mids highlighting his vocal nuances. The balanced soundstage and excellent noise cancellation ensured an engaging, immersive experience.

Overall, the Air Pro 4 deliver a dynamic and enjoyable listen. Coupled with their comfortable, snug fit, these earbuds are perfect for extended listening sessions – whether you’re powering through your workday or losing yourself in a long playlist.

Active Noise Cancellation

The ANC on the Air Pro 4 is a slight step up from its predecessor, but it still comes with most of the same pluses – and minuses – we saw in the previous model.

It works wonders on masking background and humming noises like those you’d encounter on a train, tube, or aeroplane. However, when the chatterbox next to me on the tube wouldn’t stop yapping on their phone, that audio, unfortunately, still bled through to my ears.

One new addition that’s frankly a bit perplexing is the app’s five ANC modes: Strong ANC, Balanced, AI Environment Adaptive, AI Ear Adaptive (yes, they had to include something that mentions AI) and Wind Noise.

While choice is usually a good thing, I’m not entirely sure who needs all these confusing options. To be honest, I barely noticed any difference when switching between them.

Most users will be fine just sticking with the Strong ANC option or switching to Ambient mode if they want the reverse – to hear things around you more loudly.

Despite this minor quibble, the ANC performance is still impressive for earbuds in this price range. It might not compete with top-tier noise-cancelling headphones, but it’ll certainly help you focus on your music or a Netflix show without being constantly distracted by your surroundings.

When it comes to phone calls, the EarFun Air Pro 4 continues to impress. The earbuds use an enhanced 6-mic system with a machine learning AI algorithm and cVc 8.0 technology to deliver superior call clarity. In practice, this means your voice comes through crisp and clear to the person on the other end, even in less-than-ideal environments.

One thing to note, though, is that those microphones sometimes pick up – and enhance – the “wrong” sounds – so if an ambulance passes you on the street, the person on the other side of the call may get quite startled by the volume.

EarFun Air Pro 4 Battery Times

The Air Pro 3 had impressive battery life, but EarFun has managed to up the ante even further with the Air Pro 4.

You can now use these earbuds for up to 11 hours on a single charge without ANC, and a still-impressive 7.5 hours with ANC on. That’s a noticeable improvement over the 9 and 7 hours of the previous model.

When you factor in the additional juice waiting in the case, you get a total of up to 52 hours without ANC, and 35 hours with ANC on. To put that into perspective, you could theoretically listen to music for more than two full days before needing to plug in the case.

And indeed, I’ve been using these earphones daily for almost three weeks now, and I haven’t had to recharge the case even once yet. That’s some serious staying power, especially for someone like me who tends to have music or podcasts playing for a good chunk of the day.

They’re not the best out there in terms of battery times – but there’s a good balance here between size, weight – and the timings you get.

As always, your mileage may vary depending on volume levels, the audio codec you’re using, and the distance between the earbuds and your device.

The case is charged via USB-C or with a wireless charger (though it’ll be slower that way), and the “Quick Charge” feature is still present. Just 10 minutes in the case will give you 2 hours of listening time – perfect for those moments when you’ve forgotten to charge and need a quick top-up before heading out.

Bottom Line: Are The EarFun Air Pro 4 Earphones Worth It?

EarFun’s been on a roll in recent years – and the Air Pro 4 keep that momentum going. They’ve taken what worked with the Air Pro 3 and tweaked it just enough to make these a solid step up.

The audio quality remains excellent, with support for a wide range of advanced codecs ensuring you get the best possible sound from your device. The Active Noise Cancellation, while not perfect, is impressive for this price point.

Add to that the improved battery life, comfortable fit, and the return of in-ear detection, and you’ve got a compelling package.

Best of all, the Air Pro 4 represent excellent value for money – you’re basically getting almost every feature that wireless earphones can carry these days.

So, if you’re in the market for feature-rich earbuds that punch above their weight in terms of sound quality and battery life, these should be high on your list.

But if you’ve already got the Air Pro 3 and you’re happy with them, don’t feel like you need to rush out for an upgrade. These are great, but they’re not reinventing the wheel.

For everyone else though, you’d be hard-pressed to find better value for money in the true wireless world right now.
