The Soundcore Liberty 4 is a true wireless (TWS) ANC earbud with coaxial 9.2 mm + 6 mm dual dynamic drivers, LDAC, a heart-rate sensor and head-tracked spatial audio. Rated for up to 9 hours per charge (28 with the case), it suits listeners, especially on Android, who want one pair for music, calls and workouts.
Who the Soundcore Liberty 4 is for
Android phone owners: LDAC support lets compatible Android phones stream higher-resolution Bluetooth audio, with AAC and SBC as fallbacks.
Workouts and fitness tracking: A heart-rate sensor in the right earbud feeds readings to the soundcore app, and the buds are rated IPX4 against splashes.
Movies and video: Spatial audio offers music and movie modes, and a built-in gyroscope follows head movement so the sound stays anchored around you.
Commuters: HearID personalized noise cancelling runs up to 7 hours per charge with ANC on, or 24 hours with the case.
Laptop-and-phone multitaskers: Multipoint keeps two devices connected at once (LDAC is unavailable while it is on), and six microphones with a noise-reduction algorithm handle calls.
Skip it if: you're on an iPhone and buying mainly for LDAC: iPhones can't send LDAC, so these would connect over AAC instead.

Soundcore Liberty 4 vs similar options
vs Soundcore Liberty 4 NC: One 11 mm driver instead of coaxial dual drivers, but longer battery: 10 h per charge, 50 h with case. Pick it for endurance; the Liberty 4 for heart-rate sensing and spatial audio.
vs CMF Buds Pro 2: Also runs dual drivers (11 mm + 6 mm) and is rated for 50 dB hybrid ANC; choose the Liberty 4 instead if heart-rate tracking and head-tracked spatial audio matter to you.
