EarFun Air Pro 4 review — Easy listening

EarFun has been in the audio market for a while, and they’ve now brought forward a new edition of their EarFun Air line of wireless earbuds with the EarFun Air Pro 4. Touting higher resolution audio than the Air 3s, evolution on their QuietSmart noise canceling modes and more, let’s see how these wireless earbuds fare.

Opening up the box, I was greeted by some instructional pamphlets, and just below that were the earbuds nestled in their charging case accompanied by a few accessories. These were four pairs of swappable ear tips of varying sizes, a USB-C charging cable and a small swab for cleaning the earbuds. After flipping through the instruction booklet, pairing the earbuds to my phone was as easy as opening the charging case, pressing the button on the inside to activate pairing mode, and selecting the device on my phone. 

A big plus with the Air Pro 4s is that you can pair them to two devices at once, meaning I could be listening to music on my phone, and then seamlessly transition to listening to audio on my computer without needing to open any menus or change settings. This feature does get disabled when using the LDAC audio setting, but I didn’t notice that big of an audial difference to warrant using LDAC over having the ease of having multipoint connection. This is one of the selling points as to being “pro”, but if you’re using these earbuds for Spotify or YouTube, it just isn’t that important. And if you’re using these on an Apple product, you can’t use this feature anyways, as LDAC isn’t supported on those devices.

 

Also included in the instructions are diagrams explaining all of the touch functionalities present on the earbuds. These are usually simple taps on the side of the earbuds, which perform different functions depending on how many times you tap. These can be reconfigured in the EarFun app, but the default settings will have you tap once to raise/lower volume, tap twice to pause/play and tap three times to play the next/previous track. Inputs are also reliant on which side you tap, with the “forward” inputs being on the right, and the “back” inputs on the left. While this took some learning on my part to memorize what each tap would do, after a few days it almost became second nature.

Audio is certainly one of the pillars of wireless earbuds, and thankfully the sound here is good. Compared to the traditional wired earbuds that I’ve been using for a few years, the sound is much richer and feels fuller. Sure, it won’t be the loudest bass you might get from studio headphones, but it certainly is decent quality for wireless earbuds. The equalizer found in the EarFun app also lets you tweak the audio settings, but I didn’t really see a huge difference in their preset listening options. Using these for other things like taking phone calls is easy and clear as well, with people on the other line being able to hear me without issue.

Something you’ll always want to keep in mind when looking for a good wireless product is the battery life, and the Earfun Air Pro 4s sport a pretty charge. The earbuds themselves lasted about seven hours, and can be quickly recharged in about an hour in the case. This means that if you’re topping off the charge in between listening sessions you’ll easily be able to listen for multiple days before you need to plug the case in. And even then you only need to leave the charging case plugged in for two to three hours to reach full charge again, meaning there isn’t a ton of downtime regardless. 

Comfort is another important factor when using earbuds, and while these aren’t the pinnacle of comfort, they’re still a pretty good fit. They never really came loose when going about my day, and didn’t feel too obtuse when putting them on. I really only noticed fatigue after long listening sessions, but the swappable ear tips really helped me find a fit for my ears to ease this up a bit. Even so, I did find myself needing to adjust them every so often as my ears started to feel mild discomfort when wearing them. 

 

Other features include varying levels of noise canceling depending on how much ambient sound you want to pass through, as well as in-ear detection, which will pause or play audio depending on whether or not you are currently wearing the earbuds. The noise canceling mode doesn’t exactly block out much though, I can still hear a lot of noise unless the audio I’m playing is very loud, which sort of defeats the purpose. Sure it might dampen white noise, but I can still clearly hear close sounds like the keys clicking on my keyboard when using it, which is a pretty low bar to fail. 

The EarFun Air Pro 4s do a lot well, but still have their fair share of things that they miss the mark on. For common use though, I think these perform well enough to be a good pair of everyday earbuds, but they don’t exactly offer what I would consider to be a “pro” experience.
