EarFun Air Pro 4+ Adaptive Noise Cancelling Wireless Earbuds Review

Wireless earbuds have become an essential everyday accessory, and the market is crowded with options that promise great sound, reliable connectivity, and effective noise cancellation. The EarFun Air Pro 4+ aims to stand out by combining a hybrid dual-driver design with a comprehensive feature set that extends well beyond basic listening. With support for high-resolution audio codecs, adaptive noise cancellation, and even real-time translation, these earbuds are positioned as a versatile option for users who want more from their audio gear. This review takes a closer look at what the EarFun Air Pro 4+ offers based on the product specifications and stated features.

Design & Build Quality

The EarFun Air Pro 4+ is built around a hybrid driver system housed in a true wireless in-ear form factor. The emphasis on comfort is clearly stated, with the product noting that the design is engineered for comfort, which is an important consideration for earbuds that are likely to be worn for extended listening sessions or calls. The earbuds also carry an IP55 waterproof rating, indicating a level of protection against water and dust that should make them suitable for workouts, commutes in the rain, and other active scenarios where exposure to moisture is a possibility.

One of the more interesting design details is the 11-degree angle alignment used in the driver configuration. According to the product information, this alignment is intended to minimize high-frequency attenuation, which in practical terms means the earbuds are designed to deliver a clear and accurate soundstage without losing detail in the upper frequencies. This is a thoughtful engineering choice that suggests attention to how the drivers interact with the ear canal, rather than simply placing components inside the housing without consideration for acoustic behavior.

The charging case extends the total listening time significantly, and the compact nature of the true wireless format means the entire package is designed for portability. While the exact dimensions and weight of the case are not provided, the stated battery figures give a clear picture of what to expect in terms of endurance between charges.

Features & Technology

The EarFun Air Pro 4+ is packed with technology, and the centerpiece is the dual-driver synergy system. This combines a 10mm composite dynamic driver with an ultra-light FeatherBA balanced armature. The idea behind a hybrid driver setup is that each driver handles a specific portion of the frequency range, with the dynamic driver typically responsible for bass and the balanced armature handling mids and highs. The stated result is robust bass, articulate mids, and sparkling treble, which is the kind of sound signature that aims to satisfy listeners who want detail across the entire spectrum.

Under the hood, the earbuds are powered by the Qualcomm QCC3091 system-on-chip. This chipset enables Snapdragon Sound certification with aptX Lossless support, which is significant for Android users who want to stream high-quality audio over Bluetooth. The earbuds also support LDAC, LC3, and LE Audio codecs, providing extensive compatibility with a range of devices and ensuring that the listening experience can take advantage of high-resolution audio sources when available.

The adaptive hybrid active noise cancellation is another headline feature. Using EarFun QuietSmart 3.0 technology, the earbuds are stated to detect external noises and intelligently adjust the ANC in real time, cancelling ambient noise up to 50dB. This adaptive approach means the noise cancellation is not static but rather responds to changing environments, which can be useful when moving from a quiet room to a noisy street or busy office.

For calls, the EarFun Air Pro 4+ employs a 6-mic array with AI beamforming. The system is designed to focus on your voice while Qualcomm cVc 8.0 technology suppresses background noise. This combination is aimed at ensuring clear calls even in noisy environments, which is a practical consideration for anyone who takes calls on the go or works from varied locations.

Performance & Everyday Experience

Battery life is a critical factor for wireless earbuds, and the EarFun Air Pro 4+ delivers impressive numbers on paper. With ANC disabled, the earbuds are stated to provide up to 12 hours of playtime on a single charge, extending to 54 hours with the charging case. With ANC enabled, those figures drop to 8 hours and 36 hours respectively. The quick charge feature is also worth noting: a 10-minute charge provides 3 hours of playtime, which is convenient for those moments when you need a quick boost before heading out.

It is important to note that these battery figures are sourced from EarFun Laboratory testing based on ANC disabled and 50% volume. The product information itself acknowledges that actual battery life may vary depending on volume, audio content, and whether LDAC is in use. This is a realistic caveat, as high-resolution codecs and higher volume levels typically consume more power.

Bluetooth 6.0 connectivity brings multipoint support, allowing the earbuds to connect to two devices simultaneously. This is a practical feature for users who want to switch between a laptop and a phone without manually disconnecting and reconnecting. The earbuds also support Auracast, which enables audio sharing and the ability to tune into public audio broadcasts. This is a newer Bluetooth feature that could become more useful as public venues begin to adopt Auracast-compatible systems.

In-ear detection is included, but with an important caveat: the product information notes that this feature is disabled by default in the latest firmware version. Users who want the earbuds to automatically pause playback when removed from the ears will need to enable this feature in the EarFun Audio App. This is a minor setup step but worth knowing about before purchase.

App Integration & Special Features

The EarFun Audio App plays a central role in the overall experience. Beyond enabling in-ear detection, the app is required for the real-time AI translation feature. This feature supports translation across 100+ languages and offers both real-time and face-to-face translation modes. The product information notes that the app must be updated to the latest version for this feature to work correctly, and it is reasonable to expect that translation quality will depend on the app’s implementation and the clarity of the spoken input.

The app also provides access to firmware updates, which the product recommends for the best experience. Low latency mode is another stated feature, which can be beneficial for watching videos or gaming where audio sync with visuals matters. The multipoint connection and Auracast features may also be configured or managed through the app, though the product information does not specify the exact extent of app control for each feature.

Who Is This Product Best For?

Based on the supplied information, the EarFun Air Pro 4+ appears well-suited for several types of users. The extensive codec support and dual-driver design make these earbuds a strong candidate for audio enthusiasts who prioritize sound quality and want to take advantage of high-resolution audio streaming from compatible devices. The adaptive ANC and long battery life make them practical for commuters, frequent travelers, and anyone who spends long hours in noisy environments.

The 6-mic array with AI beamforming and cVc 8.0 noise suppression suggests these earbuds are also aimed at professionals who take frequent calls and need clear voice transmission in less-than-ideal acoustic conditions. The real-time translation feature could appeal to travelers or those who communicate across language barriers, though it is worth remembering that this feature depends on the app and may require a stable connection to work effectively.

Finally, the IP55 rating and comfortable design make these earbuds suitable for active users who want to use them during workouts or outdoor activities without worrying about sweat or light rain. The multipoint connection is a bonus for those who juggle multiple devices throughout the day.

Final Verdict

The EarFun Air Pro 4+ wireless earbuds bring together a compelling combination of audio technology, noise cancellation, and connectivity features. The hybrid dual-driver system with aptX Lossless and LDAC support positions these earbuds for listeners who care about sound quality, while the adaptive ANC and long battery life address the practical needs of daily use. The addition of multipoint connection, Auracast compatibility, and real-time translation makes these earbuds more than just a simple audio accessory.

There are some caveats to keep in mind. The in-ear detection feature requires manual enabling through the app, and battery life figures are based on specific lab conditions that may not reflect real-world usage. The translation feature depends on the EarFun Audio App being up to date. However, these are minor considerations in the context of the overall feature set. For users seeking a feature-rich pair of true wireless earbuds with strong audio credentials and versatile connectivity, the EarFun Air Pro 4+ presents a well-rounded option worth considering.
