EarFun is a relatively young company. Founded by industrial designers and acoustic engineers, their goal is to bring the cutting-edge in wireless audio technology to the masses. With the Air Pro 4+, they aimed to take what they'd built into their award-winning Air Pro 4 and continue to push the boundaries. What we've gotten is an excellent set of earbuds that won't shatter your piggy bank.

Music drives our emotions, helps us cope, and motivates us. Podcasting and audiobooks keep our minds engaged in conversation, world events, or the fantastical while our bodies operate on the mundane. EarFun's Air Pro 4+ earbuds ensure we get to enjoy those experiences in comfort with the high clarity.
First, let's discuss the case. While it'll comfortably fit in the palm of your hand, it carries a weight that begs you to consider its technical prowess and value. I like it, but the larger case might be a little too much for you to carry in your pocket. Though the housing is just matte plastic, its smooth, beveled edges and vibrant front-panel LED display, which changes color based on battery charge and connection status, imply there was attention to detail and comfort taken into consideration. Folding the lid back reveals two sleek, tall earbuds nestled safely in their housing, held firm by batteries that beckon them to their place of rest. A rechargeable battery, accessible via USB-C port on the bottom of the case, is housed behind the earbuds' stasis chambers.
Taking the earbuds from the case and waking them from their cryogenic slumber, they'll either quickly sync up with your phone (or other linked device) or give you the opportunity to do so. Re-syncing, if needed, can be done by holding a small button next to the USB-C port. Once the earbuds are synced, you'll be ready to enjoy high quality audio.

The listening experience with the Air Pro 4+ is great. EarFun packs as much high-end tech into these earbuds as possible for the best user experience. I spent much of the past week indulging in the soundtrack for one of my favorite games: Clair Obscur: Expedition 33. With the Air Pro 4+ I felt like, if I were to close my eyes, I could have told you where each musician was sitting with respect to the listener. The Air Pro 4+ houses several key technologies to make this happen.
The Air Pro 4+ utilizes their FeatherBA armature with a 10mm dynamic driver. This makes sure you can enjoy those deep, reverberating bass moments and clean, crisp high notes. The earbuds feature Qualcomm's QCC3091 SoC (System on a Chip) for high fidelity audio as well as baked-in Bluetooth 6.0 for the highest quality signal. Pair that with Qualcomm's aptX Lossless, which helps deliver the purest signal with no data loss, and you're set up for a rich listening experience with audio as close to the source as you can get.
EarFun's Air Pro 4+ earbuds also feature adaptive hybrid noise cancellation up to 50 decibels to ensure you can enjoy listening without the outside world interrupting. It uses a 6-microphone array to detect the audio in the world around you, adjusting multiple times each second to give you the best listening experience with as little distraction as possible.
TLDR - EarFun packs a lot of tech in these bad boys so you can listen to the best audio with as little to distract you as possible.

For those who want more control over their experience than just throwing them in and hitting the road, EarFun offers phone apps for both Android and Apple devices. This is where a lot of the earbuds' features can be adjusted and tweaked to your own personal preference. The app has your run-of-the-mill information, like case and earbud battery power, of course, but the options it provides goes so much deeper than that.
From the app, you can adjust your listening mode: Normal, Ambient Sound, and Noise Canceling. Say you're going for a run and you want to know about environmental hazards like traffic; Ambient Sound mode may be a good choice, where getting in the zone for a long study session would warrant the Noise Cancelling [sic] mode. If you're a gamer who enjoys using your earbuds, you can activate Game Mode to reduce latency (though, admittedly, you risk your connection's quality).
The EarFun app will also let you pick from different Equalization settings. Plan on listening to some rock and roll for a while? You can flip the equalizer over for the best Rock experience. The same can be done for Pop, Country, EDM, and several more. If none of those meet your needs, you can create your own equalization to suit your tastes.
There's a lot more control the app gives you. You can adjust various touch controls on each earbud, connect to multiple devices at once, or even target an earbud to make noise in case you misplaced it and need to find it. It really is a pretty slick set of tools.

There's one thing I think feels a little bizarre to me. EarFun claims the Air Pro 4+ has AI language translation built into it. When my wife and I tried it, what we discovered was that the app has translation software like Google's own translation solution. There's one difference, in that what others say is piped into your earbuds while your translation is delivered through your phone's speaker. Their advertising may not technically be incorrect, but it feels like a bit disingenuous for the experience I was expecting.
With regards to a set of earbuds, I'd be remiss if I didn't mention battery life. EarFun claims the Air Pro 4+ will get you 8 hours of listening per charge with noise cancellation turned on or 12 hours with it off. Given the recharge capacity of the case, their claim is that a fully charged set of earbuds and case can ultimately deliver ~54 hours of listening. My own personal experience put that around ~45-50 hours between full charges, which seems pretty close to their claim, but your mileage may vary.

I'm pretty happy with the Air Pro 4+. Whether podcasts, audiobooks, YouTube videos, or music (go listen to the Clair Obscur soundtrack!), the audio quality is fantastic. I never experienced any issues, and the depth, clarity, and performance power was excellent. The battery life will give you plenty of listening time between charges, and the app puts plenty of tools in your hands to customize your experience. They're also IP55 water-resistant, so you shouldn't need to worry about a malfunction when you're sweating. Combine all that with a reasonable $100 price, and you've got a great piece of kit that you'll use every day.
