The EarFun Air Pro 4+ are wireless earbuds aimed at listeners who want more than the usual combination of music playback and noise cancellation. They bring together a hybrid dual-driver setup, Qualcomm aptX Lossless, LDAC, Snapdragon Sound, adaptive ANC, Bluetooth 6.0 and real-time AI translation.
At $79.99 in the US, they sit in a price range where buyers can expect a noticeable step up from basic wireless earbuds. EarFun has also added several practical features, including multipoint connectivity, Auracast, fast charging and a companion app with extensive EQ customization.
After testing the earbuds, the overall experience is quite positive. The charging case works well, the earbuds are lightweight, the microphones and speakers deliver solid performance, and the noise cancellation is particularly impressive. There are a few compromises, including average battery performance with ANC enabled and a fit that may need some adjustment for certain users.
EarFun Air Pro 4+ Features
Hybrid Dual-Driver System
One of the biggest differences between the Air Pro 4+ and many conventional wireless earbuds is the dual-driver design.
Each earbud combines a 10mm composite dynamic driver with an ultra-light FeatherBA balanced armature. The dynamic driver handles the lower frequencies, while the balanced armature is designed to reproduce higher-frequency details.
EarFun has positioned the two drivers at an 11-degree angle to help reduce high-frequency attenuation. The goal is to create a cleaner and more detailed soundstage without allowing bass to overpower vocals and treble.
In everyday listening, the dual-driver configuration gives the Air Pro 4+ a well-rounded approach to audio. They have enough bass for modern music while retaining clarity in the middle and upper frequencies.
Hi-Res Audio, aptX Lossless and LDAC
The earbuds use Qualcomm’s QCC3091 chipset and are certified for Snapdragon Sound with aptX Lossless support.
They also support LDAC, LC3 and LE Audio, giving compatible smartphones and other devices several options for higher-quality wireless audio.
aptX Lossless can preserve more audio detail than conventional Bluetooth compression when the source and playback device support it. LDAC provides another high-quality option for compatible Android devices.
The Air Pro 4+ are therefore particularly interesting for listeners who pay attention to Bluetooth codecs rather than simply choosing earbuds based on basic specifications.

Adaptive Hybrid ANC
EarFun’s QuietSmart 3.0 technology powers the adaptive hybrid active noise cancellation. The earbuds can detect surrounding sounds and adjust the ANC level in real time, with up to 50dB of claimed noise reduction.
The ANC performed very well during testing. It is particularly useful in environments where there is continuous background noise, helping create a quieter listening experience.
As with any ANC earbuds, actual performance depends on the ear seal, surroundings and type of noise. Finding the right ear-tip size can make a significant difference because passive isolation and active noise cancellation work together.
Real-Time AI Translation
The Air Pro 4+ add an unusual feature for this category: real-time AI translation.
Through the EarFun Audio App, the earbuds support translation across 100+ languages, with Real-Time and Face-to-Face translation modes.
This could be useful when travelling or communicating with someone who speaks another language. However, translation performance depends on the app, software and supported languages, so this feature should be viewed as an added convenience rather than the primary reason to buy the earbuds.
EarFun recommends keeping the Audio App updated to the latest version for the translation function.
6-Microphone AI Call System
For calls, the Air Pro 4+ use six microphones with AI beamforming voice enhancement.
The system is designed to focus on the user’s voice while reducing unwanted background noise. Qualcomm cVc 8.0 technology is also included to help improve vocal clarity.
The microphone quality is solid, and the earbuds work well for everyday calls and voice communication. The six-microphone setup gives the AI processing more information to work with when separating speech from surrounding sounds.
Bluetooth 6.0, Multipoint and Auracast
Bluetooth 6.0 provides the wireless connection, while multipoint connectivity allows the earbuds to remain connected to two devices at the same time.
This is convenient when using a smartphone and computer together. You can move between devices without repeatedly going through the pairing process.
Auracast is another forward-looking feature. Compatible devices can use it to share audio or connect to public audio broadcasts.
Not every user will immediately need Auracast, but its inclusion gives the Air Pro 4+ support for newer Bluetooth audio capabilities.
Battery Life and Fast Charging
Battery life is rated at up to 12 hours on a single charge in normal mode, with the charging case increasing total playback to as much as 54 hours.
With ANC enabled, the figures drop to around 8 hours for the earbuds and 36 hours including the case.
A 10-minute quick charge can provide up to three hours of playback.
These figures are based on EarFun’s laboratory testing with ANC disabled and volume at 50 percent. Actual battery life can vary depending on volume, audio content, ANC, LDAC and other settings.
In practical use, battery performance feels more average when compared with the best long-lasting earbuds, but the quick charging feature helps make up for that.
EarFun Audio App and Controls
The EarFun Audio App is one of the better parts of the overall experience. It provides multiple EQ profiles and lets users adjust the earbuds according to their preferred sound.
The controls are also responsive and can be managed through the app. Firmware updates are available through the application as well.
One detail worth knowing is that in-ear detection is disabled by default in the latest firmware version. Users who want this function need to enable it manually through the EarFun Audio App.

EarFun Air Pro 4+ Price in the US
The EarFun Air Pro 4+ are priced at $79.99 in the US and are available on Amazon.
At this price, they compete with several established wireless earbuds, but the Air Pro 4+ differentiate themselves through their dual-driver system, aptX Lossless, LDAC, adaptive ANC and AI translation.
EarFun Air Pro 4+ Review
The Air Pro 4+ make a good first impression because they are lightweight and easy to carry. The charging case works reliably and USB-C charging makes topping it up simple.
The fit is comfortable for me during normal use. However, when lying down, the earbuds can slowly move out of the ears. This isn’t necessarily a problem for everyone, but switching to a different size of the included ear tips may provide a more secure fit.
The sound quality is one of the stronger aspects of these earbuds. The combination of the 10mm dynamic driver and FeatherBA balanced armature gives the Air Pro 4+ a balanced presentation with plenty of detail.
Bass has a good presence without completely taking over the rest of the frequency range. Vocals remain clear, while higher frequencies have enough energy to make instruments and other details easier to distinguish.
The multiple EQ profiles in the app are also useful. If the default sound isn’t exactly what you prefer, there are several ways to change the presentation.
Noise cancellation is another highlight. The adaptive ANC worked very well during testing and helped reduce surrounding noise without requiring the volume to be pushed excessively high.
Call quality is also solid. The six microphones and AI beamforming system do a good job focusing on speech, making the Air Pro 4+ suitable for regular phone calls and online conversations.
The battery case performs reliably, although battery life feels more average compared with some models that focus heavily on endurance. The quick-charge feature is useful, though. A short 10-minute charge can add several hours of listening time.
The app deserves credit as well. It provides plenty of control without feeling unnecessarily complicated. EQ profiles, firmware updates and other settings are accessible from one place.
The earbuds are also a good choice for people who occasionally use wireless earbuds or carry them in situations where losing an expensive pair would be frustrating. At $79.99, they aren’t the cheapest option, but they avoid the much higher cost associated with some premium earbuds.
For someone whose only priority is getting the absolute best music experience, larger headphones can still provide advantages in areas such as soundstage and overall audio presentation. But as compact everyday earbuds, the Air Pro 4+ provide a strong combination of sound, ANC and convenience.
