Used Soundcore Liberty 4 Pro True Wireless Noise-Cancelling In-Ear Earbuds

The Soundcore Liberty 4 Pro is engineered for listeners who demand audiophile detail and industry-leading noise control in a compact true-wireless package. A dual-driver acoustic layout and Soundcore’s ACAA tuning deliver tight, controlled bass and crystalline highs — while LDAC support and Bluetooth 5.3 preserve high-resolution streams from compatible devices. Adaptive real-time ANC uses a 7-sensor array (six sound sensors plus a barometric sensor) to sample ambient noise and rebalance cancellation multiple times per second, delivering deep attenuation in complex environments such as aircraft cabins, trains and busy commutes. The earbuds pair rapid charging and extended runtime with a charging case that features an integrated display for on-the-fly battery and ANC control, making the Liberty 4 Pro a practical choice for frequent travelers and daily commuters.
