TechRadar praises the Air Pro 4's upgraded Bluetooth 5.4, LDAC support and lightweight 5 g design, noting solid high-resolution sound despite the smaller driver, while SoundGuys highlights the comfortable fit, IPX5 durability and improved ANC, though both acknowledge the sound can become tinny at high volumes and that the ANC is not flagship-class.
Everyday users appreciate the stable 15 m range, intuitive touch controls, effective ANC for commuting and gym use, long battery life, and the app's fit test that improves seal and sound. Common complaints revolve around occasional connectivity drops, reduced ANC when the fit is loose, tinny highs at loud volumes, and inconsistent wireless charging of the case.
Professional reviewers describe the Truefree B1 as a compelling budget option for fitness enthusiasts who need lightweight, open-ear earbuds with solid mids, reliable Bluetooth 5.4 multipoint connectivity, and long battery life. While the spatial audio and low-latency performance are praised, the limited bass depth and lower overall volume keep it from competing with higher-priced models.
Everyday users appreciate the B1's feather-light comfort, secure clip-on fit, and long battery life, especially for outdoor workouts and commuting. Common praise centers on situational awareness, clear call quality, and the ability to switch between devices. Recurring complaints focus on thin bass, lower maximum volume, and occasional discomfort during extended wear.
Choose Air Pro 4 for newer Bluetooth features and better ANC; stick with Air Pro 3 if you prefer the slightly larger driver and can forego LDAC.
