Review

The Anker Soundcore Liberty 4 Pro is a true wireless earbud focusing on advanced noise cancellation and intuitive controls. It features Ultra Noise Cancelling 3.5, utilizing seven sensors to detect environmental noise 180 times per minute for scene-specific optimization [S1]. For audio quality, the A.C.A.A 4.0 system employs two upgraded drivers—one for lows and one for mids/highs—to pursue clear sound with minimal distortion [S1]. Notably, the device offers versatile controls via pressure and swipe sensors on the earbuds, as well as a touch bar and screen on the charging case, allowing mode adjustments without needing an app [S1]. Battery life reaches up to 10 hours per charge and 40 hours total with the case in normal mode, including a quick-charge feature providing roughly 4 hours of playback from a 5-minute charge [S1]. Please note that specific IPX waterproof ratings and a full list of supported codecs are not verified in the provided documentation.
