EarFun Air Pro 4+ TW700B Adaptive ANC Dual Driver Bluetooth 6.0 50dB 12h Black

Hybrid dual-driver earbuds for critical listening

The EarFun Air Pro 4+ combines a 10mm composite dynamic driver with a FeatherBA balanced armature set at an 11-degree angle. This hybrid architecture targets accurate reproduction across a 5Hz-40KHz response range with 32-ohm impedance. Qualcomm QCC3091 silicon enables Snapdragon Sound aptX Lossless plus LDAC and LC3 codec support. Built for listeners who prioritise resolution over convenience features.

Adaptive ANC sustains up to 50dB reduction

QuietSmart 3.0 analyses ambient sound in real time and adjusts cancellation depth continuously rather than relying on a fixed profile. The 12-hour single-charge endurance holds with ANC active, while a 10-minute top-up returns useful playback time. Bluetooth 6.0 maintains a stable link during extended sessions. Buyers who need all-day battery without a case recharge should look elsewhere.

In-ear fit and app-dependent translation

Three ear-tip sizes are included to seal the 53-gram housings securely in each ear. The EarFun Audio app handles firmware updates, EQ presets and the 100-language AI translation modes; translation will not work without the latest app version. Touch controls cover playback, calls and ANC toggles. Users who dislike in-ear pressure or prefer physical buttons may find the fit fatiguing.
