EarFun Air Pro 4 Plus

Name: EarFun Air Pro 4 Plus
Brand: EarFun
SKU: 51927

Manufacturer: EarFun

The EarFun Air Pro 4 Plus are true wireless in-ear earbuds designed for everyday wireless listening. Rated IP55 for water and dust resistance, they fit securely without neckbands or wingtips, and come with a carrying case included in the box. Active noise cancellation is supported alongside a passive noise isolation design, giving listeners control over how much of their environment they hear through a dedicated ambient sound mode.

On the connectivity side, the EarFun Air Pro 4 Plus supports Bluetooth 6 with a broad codec range that includes LDAC, aptX Adaptive, aptX Lossless, LE Audio, AAC, and Auracast, with a quoted audio latency of 50 ms. The earbuds pair with up to two devices simultaneously via multipoint connection and offer fast pairing support. Battery life reaches 12 hours per charge, or 8 hours with ANC enabled, and the charging case extends total playback to 42 hours; wireless charging and fast charging are both available. A six-microphone array with noise cancellation handles calls and voice input, while onboard controls, voice prompts, in-ear detection, and a built-in translator round out the feature set. The warranty period is 1.5 years.

Pros

Supports a wide range of high-quality audio codecs including LDAC, aptX Adaptive, and aptX Lossless, covering most high-resolution wireless audio scenarios
Multipoint connection allows simultaneous pairing with two devices, useful for switching between a phone and a laptop without re-pairing
Both wireless charging and fast charging are supported, adding flexibility to how the earbuds are powered up
The six-microphone array with noise cancellation is well-suited for calls in noisy environments
IP55 rating provides meaningful protection against dust and water splashing, making the earbuds usable during workouts or light rain
A built-in translator and ambient sound mode add practical utility beyond standard audio playback

Cons

Maximum Bluetooth range of 10 m is relatively short, limiting freedom of movement from a paired device
Spatial audio, Dolby Atmos, and Dirac Virtuo are all absent, which reduces immersive listening options
Battery life drops from 12 hours to 8 hours with ANC enabled, which may require more frequent charging for heavy ANC users
No NFC pairing support, meaning device connections must be set up manually through Bluetooth settings
Wingtips are not included, which may affect fit stability during high-movement activities for some users

Who is this for?

These earbuds are well matched for commuters and frequent travelers who want reliable active noise cancellation combined with the flexibility of an ambient sound mode to stay aware of their surroundings when needed. The IP55 rating and true wireless design make them a practical choice for gym use and outdoor activity in variable weather. Users who move between multiple devices throughout the day will benefit from multipoint pairing, and those invested in high-resolution audio will find broad codec support — including LDAC and aptX Lossless — a meaningful advantage. The six-microphone noise-canceling setup also suits people who rely on their earbuds for frequent voice calls or remote work.

Who is this NOT for?

Users who prioritize spatial audio or immersive surround formats will find these earbuds limiting, as Dolby Atmos, Dirac Virtuo, and spatial audio are all absent. Those who engage in high-intensity sports requiring a very secure fit may find the lack of wingtips a drawback, since there is no option to anchor the earbuds more firmly in the ear. The 10 m Bluetooth range is also a constraint for anyone who needs reliable connectivity while moving freely around a larger space, such as a home or studio environment. Additionally, listeners who prefer a fully hands-free setup without any manual pairing steps may be put off by the absence of NFC pairing support.

Final Verdict

The EarFun Air Pro 4 Plus present a well-rounded set of specifications for a true wireless earbud aimed at everyday listeners who value both audio quality and practical versatility. The combination of active noise cancellation, IP55 protection, and a broad high-resolution codec lineup — spanning LDAC, aptX Adaptive, and aptX Lossless — gives the earbuds a strong technical foundation that goes beyond what entry-level wireless options typically offer. While the absence of spatial audio formats and the modest 10 m Bluetooth range reflect certain trade-offs, these are unlikely to be dealbreakers for the primary audience this product is built for. For commuters, remote workers, and active users who want reliable noise cancellation, flexible multi-device pairing, and capable call quality in a compact wireless package, the EarFun Air Pro 4 Plus represent a technically solid choice.
