We’ve been testing the EarFun Air Pro 4 earbuds extensively over the past few weeks, and they’ve proven to be a solid option for anyone seeking quality wireless earbuds without breaking the bank. Here is our earfun air pro 4 review 2026:
These earbuds earned CNET’s Editor’s Choice Award, and after using them daily for music, calls, and workouts, we can see why they’ve gained attention in the crowded earbud market.
The adaptive noise canceling does a commendable job blocking out ambient sound during our commutes and gym sessions. We found the QuietSmart 3.0 technology automatically adjusts to our ear canal shape, creating an effective seal that reduces outside noise significantly.
Sound quality impressed us right away. The Qualcomm Snapdragon Sound with aptX Lossless delivers crisp highs and solid bass that holds up well across different music genres. Support for LDAC and other high-fidelity codecs means compatibility with various devices while maintaining audio quality.
Call quality stands out as one of the stronger features. The six built-in microphones with AI algorithms and Qualcomm cVc 8.0 technology make conversations clear even in noisy environments. We took calls while walking on busy streets and in windy conditions, and people on the other end consistently reported good clarity.
Battery life meets expectations with around 11 hours per charge and up to 52 hours total with the charging case. The quick charge feature came in handy when we needed a fast power boost before heading out.
The multipoint connection works smoothly, letting us switch between our laptop and phone without manual reconnecting. Bluetooth 5.4 provides a stable connection with minimal dropouts during our testing period.
We did notice the touch controls can be slightly sensitive at times, occasionally registering unintended commands when adjusting the fit. The companion app offers EQ customization, though it takes some experimentation to find your preferred sound profile.
Bottom Line
The Air Pro 4 earbuds deliver strong performance across noise cancellation, sound quality, and call clarity at a competitive price point.
We found them reliable for daily use whether working out, commuting, or taking calls throughout the day.

Adaptive Hybrid Noise Canceling
The technology on these earbuds impressed us during daily commutes and gym sessions. The Air Pro 4 uses QuietSmart 3.0 to automatically analyze your ear canal shape and adjust the noise cancellation up to 50dB accordingly.
We found this adaptive approach worked well in varied environments. On public transit, the system effectively reduced rumbling engine sounds and passenger chatter. At the gym, we appreciated the wind noise canceling option that several users mentioned as particularly useful during outdoor workouts.
The automatic adjustment means we didn’t need to constantly fiddle with settings when moving between quiet offices and noisy streets. Background noise reduction was consistent without creating that uncomfortable pressure sensation some ANC earbuds produce.
During our testing, the adaptive system did take a few seconds to calibrate when first inserted, but after that initial adjustment, it maintained strong noise isolation throughout extended wear.

Qualcomm Snapdragon Sound and aptX Lossless Audio
The audio quality impressed us right from the first listen. These earbuds use Qualcomm’s QCC3091 chip with aptX Lossless technology, which means they can handle high-resolution audio files without compression when paired with compatible devices.
We noticed the bass had real depth without overwhelming the mids, and the treble stayed clear even at higher volumes. The Air Pro 4 also supports LDAC, LE Audio, and LC3 codecs, giving us flexibility depending on what device we connected to.
The Snapdragon Sound certification isn’t just marketing talk. We tested these with lossless tracks and could hear details in songs that typically get lost with standard Bluetooth earbuds. Vocals came through naturally, and instruments had proper separation in busy mixes.
The main limitation is that you need a device with the right codec support to get the full lossless experience. Standard connections still sound good, but you won’t hit that premium audio quality without compatible hardware.

Crystal-Clear Calls With AI and 6-Microphone ENC
Call quality stood out during our testing, particularly in noisy environments. The Air Pro 4 uses six built-in microphones combined with Qualcomm’s cVc 8.0 technology and AI algorithms to filter out background noise effectively.
We made several calls from busy coffee shops and outdoor settings, and the person on the other end consistently reported clear audio without distracting ambient noise. The system does a solid job isolating vocals while suppressing wind, traffic, and crowd noise.
Key call features:
- 6 microphones working together
- AI-powered noise suppression
- Qualcomm cVc 8.0 enhancement
The technology delivers on its promise for professional calls and casual conversations alike. We found the microphone performance competitive with earbuds priced significantly higher.

Exceptional Battery Life and Fast Charging
We were genuinely impressed by how long the Air Pro 4 lasted between charges during our testing period. The earbuds delivered around 11 hours of continuous playback on a single charge, which easily got us through multiple workdays without needing the case.
The charging case extends total playtime to approximately 52 hours, meaning we only needed to plug in once every week or two depending on usage. What really stood out was the quick charge feature—just 10 minutes in the case provided roughly 2 hours of listening time, which saved us more than once when we forgot to charge overnight.
The case uses USB-C charging and takes about 2 hours for a full charge. We found the battery indicators reliable and appreciated not constantly worrying about running out of power during commutes or long work sessions.

Seamless Multipoint Connection and Bluetooth 5.4
Switching between devices felt effortless during our testing. The Air Pro 4 can connect to two Bluetooth devices at once, which proved incredibly useful when we needed to jump from watching videos on a tablet to taking a call on our phone without manually reconnecting.
The Bluetooth 5.4 technology delivered a stable connection throughout our use. We noticed minimal dropout even when moving around the house with our phone in another room. The power efficiency seems improved compared to older Bluetooth versions we’ve tested.
Android users will appreciate the Google Fast Pair integration, which made initial setup nearly instant. The connection remained solid during our commute and workouts. One minor drawback is that some users report occasional pairing quirks when switching between saved devices, though we didn’t experience this issue during our time with them.

App Integration and Customizable Sound Profiles
The companion EarFun Audio App provides straightforward control over the Air Pro 4’s sound characteristics. We found the Sound Profile feature particularly useful for adjusting the EQ to match different music genres and listening preferences. The interface is clean and responsive, making it easy to tweak settings without frustration.
Key customization options include:
- Custom EQ adjustments through the app
- Touch control configuration
- Firmware updates (note that a reset is required after upgrading)
The app doesn’t overwhelm with unnecessary features, which we appreciated. However, it’s worth mentioning that some users reported needing to reset their earbuds after firmware updates, which adds an extra step to the process. The touch controls can also be customized through the app, giving you flexibility in how you interact with the earbuds during daily use.
Overall, the app integration works well for basic customization needs without being overly complicated.

The companion app provided genuine customization options. We spent time adjusting the EQ settings to match our preferences, which made a noticeable difference in how music sounded across different genres.
Cons

Firmware updates proved somewhat cumbersome. Following the reset instruction after updating added an extra step we found inconvenient, though it only happened occasionally.
While the sound quality delivered good detail, we noticed the bass response sometimes felt slightly overpowering on the default EQ setting. This required manual adjustment through the app to achieve our preferred balance.
Multipoint connection worked as advertised but occasionally required manual intervention when switching between devices. The transition wasn’t always as seamless as we hoped during our testing period.
