EarFun Air Pro 4+ 54H noise‑cancelling earbuds

This pair of EarFun wireless earbuds blends adaptive noise cancelling with a hybrid dual-driver layout for attentive listeners who want detailed sound while commuting, working or relaxing. The adaptive ANC and multi-mic call system keep distractions to a minimum, while support for aptX Lossless and LDAC aims to preserve high-resolution audio when paired with compatible devices.

Key Points

The EarFun Air Pro 4+ focuses on balanced, high-resolution playback thanks to a 10 mm dynamic driver combined with an ultra-light FeatherBA balanced armature, tuned with an 11° alignment to reduce high-frequency loss. Qualcomm QCC3091 silicon and certification for Snapdragon Sound support aptX Lossless for clearer, less compressed streaming where available. Adaptive QuietSmart 3.0 active noise cancelling adjusts in real time and can reach up to 50 dB attenuation according to the manufacturer, which helps in noisy environments. Battery life extends to a total of up to 54 hours with the charging case and up to 12 hours on a single earbud charge, with fast charge delivering about three hours' playback from a 10 minute charge.

Advantages

The combination of codecs—aptX Lossless and LDAC—means higher resolution is available when your phone or source supports them. Call performance benefits from the six-microphone array and AI filtering, which tends to reduce background conversation and wind noise during calls. Multipoint pairing is convenient when switching between a laptop and a phone, and Auracast support opens the possibility of listening to public audio streams when they are available.

Usage Recommendations

For the best audio fidelity, pair the earbuds with a device that supports aptX Lossless or LDAC and ensure the latest firmware is applied via the EarFun companion app. Use the adaptive ANC in busy settings such as trains or airports to reduce ambient noise, and switch to ambient/pass-through modes when situational awareness is required. Consider that the maximum ANC figure is according to the manufacturer and actual performance will vary with fit and surroundings. The fast-charge feature is useful for short journeys when a full recharge is not possible.
