The Air Pro 4 is a pair of true wireless earbuds built around a Qualcomm QCC3091 chip with Bluetooth 5.4. They use 10 mm composite dynamic drivers and support the aptX Adaptive, LDAC, SBC and LC3 codecs, and carry Snapdragon Sound and Hi-Res Audio certifications. The QuietSmart 3.0 noise cancellation adjusts automatically to ambient noise and fit, or can be set manually to high, normal or low, and an ambient sound mode lets outside sound through.
Calls use a six-microphone array with an AI algorithm and cVc 8.0 noise suppression. Other features include in-ear detection that pauses playback when an earbud is removed, dual-device connection, Google Fast Pair on Android, a low-latency mode under 50 ms and IPX5 sweat and water resistance. The EarFun Audio app for iOS and Android provides a 10-band EQ, sound modes and sound personalization, and lets the user switch the voice prompts to the EarFun Tones set. Auracast and LE Audio are available through a firmware update.
The case charges over USB-C or wirelessly. With ANC off the earbuds run up to 11 hours, or 52 hours including the case; with ANC on, up to 7.5 hours and 35 hours in total.
