EarFun Air Pro 4 are adaptive hybrid active‑noise‑canceling earbuds that claim up to 50 dB of ANC, using QuietSmart 3.0 technology that adapts to the shape of each ear canal. The earbuds are built around Qualcomm’s QCC3091 SoC and support Snapdragon Sound with aptX Lossless, LDAC, LE Audio and LC3 codecs, delivering bass, mids and treble as described by the manufacturer. CNET has named the Air Pro 4 an Editor’s Choice, noting the “surprisingly good performance and a robust feature set for an affordable budget” at a listed price of $53.
According to the specifications, the earbuds provide up to 11 hours of playback on a single charge and, together with the USB‑C case, a total of 52 hours of use; a 10‑minute quick charge adds roughly 2 hours of listening. Bluetooth 5.4 with multipoint connection lets the earbuds pair with two devices simultaneously, and the integrated Google Fast Pair streamlines setup on Android. Six built‑in microphones, AI algorithms and Qualcomm cVc 8.0 aim to reduce background noise for clearer calls, while the companion EarFun app offers customizable EQ profiles.
