Score: 73/100Rankings

The EarFun Air Pro 3 offers hybrid ANC, aptX Adaptive, wireless charging and a solid 45 h total battery life. Its ANC isn't flagship-class and wireless charging may be flaky. Best for budget-conscious commuters and gym users who want ANC without a premium price tag.

The Truefree B1 are ultra-light open-ear clip-on earbuds offering 10.8 mm drivers, spatial audio and up to 25 hours of total playback with multipoint connectivity. They sacrifice deep bass and maximum volume for lightweight comfort and situational awareness. Perfect for fitness enthusiasts and commuters who need long battery life and a secure fit.

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.
