The Earfun Air Pro 4 are true wireless in-ear earbuds designed for everyday use without the hassle of cables. Weighing just 10 grams per earbud, they carry an IPX5 water resistance rating and come with a travel bag included. Active noise cancellation is built in alongside a passive noise isolation design, giving listeners control over how much of their environment they let in through an ambient sound mode.

On the connectivity side, the Earfun Air Pro 4 support Bluetooth 5.4 with a maximum range of 15 meters and are compatible with LDAC, aptX Adaptive, aptX Lossless, and Bluetooth LE Audio, including Auracast broadcast audio. Audio latency sits at 50 ms, and AAC is also supported. The earbuds deliver up to 11 hours of playback on a single charge, extending to 20.5 hours with the 600 mAh charging case, with ANC reducing that figure to around 7.5 hours. Wireless charging is supported, and fast charging is available with a full charge taking approximately one hour. Six microphones handle call and voice pickup, backed by noise-canceling mic technology and a sensitivity rating of -38dBV/Pa. Multipoint connection allows pairing with up to two devices simultaneously.

Pros

Supports a wide range of high-quality audio codecs including LDAC, aptX Adaptive, aptX Lossless, and Bluetooth LE Audio with Auracast
Six noise-canceling microphones with a broad frequency pickup range make for capable call handling
Multipoint connection allows simultaneous pairing with two devices, useful for switching between a phone and laptop
Wireless charging is supported alongside fast charging, with a full charge completed in approximately one hour

Cons

Battery life drops noticeably from 11 hours to 7.5 hours when ANC is enabled
Spatial audio, Dolby Atmos, and Dirac Virtuo are all absent, limiting immersive audio options
No NFC pairing support, which can make the initial connection process less convenient on compatible devices
Wingtips are not included, which may affect how securely the earbuds fit during physical activity
Notification readout is not supported, reducing hands-free convenience for some users

Who is this for?

The Earfun Air Pro 4 are well suited to commuters and daily users who want effective active noise cancellation paired with broad codec support for high-resolution wireless audio. The IPX5 water resistance and lightweight 10-gram build make them a practical choice for workouts and outdoor use, while multipoint connectivity and a capable six-microphone system cater to people who regularly switch between devices or take frequent calls throughout the day. Those who value wireless convenience will also appreciate the support for both wireless and fast charging.

Who is this NOT for?

Users who prioritize spatial or immersive audio experiences will find the lack of Dolby Atmos, Dirac Virtuo, and spatial audio support a meaningful limitation. The ANC-on battery life of 7.5 hours may also fall short for travelers or long-haul users who need full noise cancellation throughout extended sessions without access to a charging case. Additionally, those who require a very secure fit during intense physical activity may find the absence of wingtip stabilizers a drawback, as the earbuds rely solely on the in-ear fit for retention.
