EarFun knows how to deliver an exceptional product for the money, and the Air Pro 4+ wireless earbuds prove it once again. For $99, they punch well above their weight. They deliver on high-end features like advanced codecs and potent active noise cancellation (ANC), and they sound superb with a wide variety of music genres. Some of the app's settings and tools are half-baked, and their Bluetooth LE Audio support isn’t perfect. But that’s really just EarFun struggling to earn extra credit on what’s otherwise a fundamentally excellent product for the money. The Air Pro+ earphones earn our Editors' Choice award for affordable noise-cancelling earbuds, replacing the still-excellent but more expensive Anker Soundcore Liberty 5 ($129.99).
Design: The Changes Are Invisible
EarFun didn’t entirely reinvent its earbuds with the Air Pro 4+. They've changed little outwardly from their predecessors, the Air Pro 4, which in turn hadn’t changed much from the Air Pro 3. The buds weigh just shy of 0.2 ounces apiece, and the charging case weighs 1.5 ounces. The buds offer IP55 protection, so you won’t have to worry much about dust, rain, or sweat—just don’t submerge them in liquid.
A new charging case with a diagonal seam can help avoid the common earbud issue of popping open and ejecting the buds when dropped onto the ground, though they're still not immune when dropped from high enough. It's a bit awkward to get the buds in and out. They don’t just plop into their spots perfectly every time; they can topple over into the lid, making them tricky to extract.

Some competitors have shifted over to pressure-sensitive controls that can be more consistent and harder to accidentally activate, so the Air Pro 4+ earbuds feel a tad behind, though the controls worked reliably in testing. Like the prior model, the buds still have wear sensors that automatically pause and resume playback when you remove or insert them.
Inside is where EarFun makes the most upgrades. Somehow, the company has managed to increase the battery capacity from 54 to 60mAh while squeezing in an extra speaker. The Air Pro 4+ earphones feature a 10mm composite dynamic driver and a secondary balanced armature slightly offset from the first to handle the high-end.
The buds also feature a new Bluetooth chip, bringing them up to Bluetooth 6.0. Otherwise, they still come with the same long list of supported codecs, which have been a highlight of EarFun’s Air Pro line. You’ll get LC3, AAC, LDAC, LHDC, aptX adaptive, and aptX Lossless. With Bluetooth LE Audio, you’ll get Auracast capabilities, which we’re starting to see pop up here and there. The buds also support Google Fast Pair and Bluetooth Multipoint, and they can keep multipoint active even with LDAC enabled (though it’s not recommended).
(Credit: Mark Knapp)One of the perks for Bluetooth LE Audio—on PC anyway—is the ability to use the microphone without sacrificing the audio playback quality. However, the Air Pro 4+ earbuds had trouble with this in my testing. When paired with a laptop that supports Bluetooth LE Audio, the buds would play audio just fine, but the second the laptop called up the mics, the buds would reboot. From there, it was inconsistent whether the buds would reconnect properly. The mics could start if no audio was playing, but that’s not good enough. The issue persisted when used with a second LE Audio-capable laptop as well. I tested a different set of LE Audio-capable headphones that managed the hand-off without this issue, so it appears EarFun’s buds are at fault here.
The Air Pro 4+ buds are rated for 12 hours of playback without ANC, and the case brings the total to 54 hours, a small upgrade over the predecessor. Playback time sinks a lot with ANC enabled, hitting just 8 hours, or 36 including the case. Still, that’s enough to get through the workday on a single charge and most of the week with the case. In my testing, the battery life largely held to that estimate, and when they're completely drained, 10 minutes in the charging case is enough to get 3 hours of listening time.
The case continues to offer both wired and wireless charging, and now features a colored indicator light to show charge and pairing statuses. Inside, it has the same 600mAh extra battery capacity as its predecessor. The case should only take between 80 and 100 minutes to recharge with a standard 5W charger, though none is included in the package. A USB cable and a variety of different-sized eartips are included.
App Experience: Loads of Features
The Air Pro 4+ earphones work with EarFun’s app, which unlocks their full capabilities. You can use them without it, but you’d be missing out on a lot. The app doesn’t require an account to use.

You can toggle game mode to lower latency, though it’ll never go away entirely on wireless. The app provides a bunch of EQ presets and a custom 10-band equalizer from 31.5Hz to 16KHz. It also has a tool to test your hearing and build a custom EQ based on that. I didn’t find its results very compelling; it did help improve the presence and brilliance a bit, but it did so by largely subduing the mids.

The app also lets you customize the on-ear controls and the behavior of in-ear detection. It lets you choose different codecs, enable Multipoint, swap voice prompt languages, toggle LE audio settings, and connect to Auracast broadcasts. There’s a tool to cap the max volume to protect your hearing, though it doesn’t include any helpful data or assessments to guide your selection, as Anker’s app does. A Find Headphones tool can help you locate dropped earbuds by emitting a high-volume beep.
And just as how every new product in 2026 tacks on some AI features, the Air Pro 4+ earphones come with one of their own: an AI-powered live translation tool baked into the EarFun app, similar to what some AirPods offer. It features two-way conversation translation and a longer-form option for one-way translation, and supports many languages.
(Credit: EarFun)The conversational tool is a little tedious to use, as it requires going back and forth, tapping a separate button for each speaker, and waiting for the translation to complete. But for simple sentences to exchange basic ideas, it seems to do the job well. Whenever it completes a translation, it plays it in your selected language through the earbuds. It can even flip the view of one of the translation boxes for easy two-person viewing. The feature tends to interpret brief pauses as the ends of sentences, which can result in some stilted translation. The continuous, one-way translation has a similar issue with breaking up sentences, making it less reliable.
Noise Cancellation: Surprisingly Potent
Great ANC is hard to expect from a cheaper earbud, but EarFun has delivered time and time again, and the Air Pro 4+ earphones don’t disappoint. In busy cafes, they do a solid job of cancelling out the hubbub. Without audio playing, I can still pick up voices faintly, but the sound of the HVAC and kitchen noise is thoroughly subdued. Without ANC, all of those lower noises slip back in, but nearby voices actually end up sounding a little more muffled. The passive isolation is fair, providing the earbuds with a strong foundation for ANC.
The buds support a few different ANC modes. You can opt for manual adjustment, let the buds automatically adjust to your surroundings, or see them adapt to your ear fit. Although the environment adaptive mode will probably be the most useful, I did find one case when switching over to the Ear Adaptive mode canceled out nearby fan noise more effectively. They also feature wind noise cancellation, which aims to provide ANC without letting the mics pick up the sound of the wind and pass it through. This unfortunately doesn’t work alongside the standard ANC modes and is instead a separate, weaker ANC implementation.
The Transparency mode is reasonably clear. It’s not perfect, but it does a good job of presenting my surroundings without having to remove the buds.
Sound Quality: Largely Balanced, With Punchy Bass
EarFun has proven over several device generations that it can deliver strong audio that goes well beyond what you’d expect for the price, and the Air Pro 4+ earphones carry on that legacy. The buds are more than capable of extreme depth, hitting the deep sub-bass notes in Kendrick Lamar’s “Loyalty” with ease. The bass doesn’t muddy up the track either. The drums hit hard, the Bruno Mars sample is crisp throughout, and Kendrick and Rihanna’s vocals are perfectly clear.
That strength in the bass plays out nicely in The Knife’s “Silent Shout.” The track’s intro consists of bass triplets and deeper sub-bass quarter notes that the Air Pro 4+ earbuds punch out with ease. Even as the track shifts its attention to the synth melody, the buds keep the bass clear while offering a bright, energetic sound for that synth. The vocal harmonies are also presented well, letting the stylized phasing between the voices come through clearly. There’s room for a little extra brilliance at the high end, but the buds don’t feel terribly lacking there.
In Bill Callahan’s “Drover,” the acoustic rhythm guitar is nice and warm, but the strings don’t have all the sparkle they could. The hi-hat hits also just lack a hint of bite. The electric guitar plays nicely in the midrange, where it gets a clear sound. Callahan’s baritone vocals are loud and focused, benefiting from the solid upper bass. The track’s many subtleties also come through well. As the song builds to its climax, the drums verge on thunderous, with the bass pushing a hair too hard, but it still doesn’t drown out the rest of the mix.
With strong frequency response, the Air Pro 4+ earbuds work well for symphonic music as well. In John Adams’ The Gospel According to the Other Mary, the buds happily reproduce the breadth of instruments included. The lead vocals come through clean without being drowned out. The deepest instruments hit with force, giving the sound plenty of weight. It can feel bottom-heavy at times from the buds’ boosted bass, and the slight shortcoming in brilliance shows with the brass, which lacks some of its bite. But all in all, the buds prove a solid platform for listening to just about any genre.
The mics on the earbuds pick up my voice loud and clear. I sound only a little distant, like I’m on speakerphone, but not so far off that it’s hard to hear. They don’t appear to cancel out much background noise, with plenty of it slipping into a test recording.
