Product details
Soundcore Liberty 4 Pro combines dual-driver sound with adaptive noise cancellation and a charging case that has its own display and touch bar. The in-ear design uses replaceable ear tips, with different sizes provided to help you find a secure fit. Choose between the supplied Black, Blue, White, Green and glossy finishes while retaining the same core audio features.
Each earbud uses 10.5mm and 4.6mm dynamic drivers. Soundcore’s ACAA system combines a bass driver, titanium-coated tweeter and digital crossover. The supported Bluetooth codecs are SBC, AAC and LDAC. LDAC requires a compatible device and app settings; it uses more power and can reduce playtime. The manual states that LDAC cannot operate with dual connections or Spatial Audio simultaneously.
Adaptive ANC 3.0 uses six sound sensors and a barometric pressure sensor, with adjustments described at 0.3-second intervals. Ambient sound controls allow a different listening balance when surrounding sound is needed. Fit affects both bass and noise reduction, so use the app’s fit guidance and suitable tips. Noise cancellation should not be treated as complete isolation from every environment.
Bluetooth 5.3 supports compatible wireless audio devices, with dual connections available for two paired devices. Six microphones and Soundcore’s noise-reduction processing support calls. Stem squeeze and slide controls handle supported actions, while the case touch bar adjusts selected functions. The soundcore app provides HearID sound, equaliser options, Spatial Audio settings, firmware updates and case control configuration.
With ANC off, the official guide quotes up to 10 hours from the earbuds and 40 hours total including case charging. With ANC on, those figures become up to 7.5 hours and 30 hours total. Volume, codec, calls and settings affect actual use. A five-minute earbud charge provides up to four hours under the stated conditions. The guide lists earbud charging up to 40 minutes, and the empty case charging in approximately 2.5 hours by cable or 3.5 hours wirelessly.
The earbuds carry an IP55 rating in the model-specific guide; this does not establish the same protection for the case. Dry the earbuds and USB-C port before charging. The set includes earbuds, charging case, replaceable tips and the provided USB-C charging cable. Follow the supplied instructions for fitting, pairing and care.
