Headset Anker Soundcore Liberty 4 Pro TWS Bluetooth in-ear, branco, para chamadas/música/desporto, peso 61,97 g

Liberty 4 Pro true-wireless earbuds provide active noise cancelling with seven sensors and adaptable settings for uninterrupted listening. The earbuds support LDAC on compatible Android devices and combine a 10.5 mm bass driver, titanium-coated tweeter and ACAA acoustic architecture for detailed Hi‑Fi sound. Fast charging delivers up to 10 hours from a single charge and up to 40 hours with the charging case, while a touch bar and case display let you adjust noise-cancelling levels quickly.

Advantages

Seven sensors (six sound sensors and one barometric pressure sensor) enable precise, 3× stronger noise reduction across varied environments. The system recalibrates noise cancelling every 0.3 seconds for consistent performance. Super fast charging provides 4 hours of playback after a 5‑minute charge. The earbuds include six microphones with AI noise-reduction algorithms and wind-noise suppression for clearer calls. LDAC support on Android allows high-resolution wireless audio.

Recommendations

For optimal noise cancelling, ensure the earbuds form a proper seal in your ear canals and keep the soundcore app updated. Enable LDAC only on compatible Android devices. Use the touch bar for quick adjustments during travel or noisy environments.
