The Anker Soundcore Liberty 4 NC earbuds are equipped with 11 mm dynamic drivers and a closed-back acoustic system, supporting a frequency response from 20 Hz to 40,000 Hz. These true wireless earbuds connect via Bluetooth 5.3 and support the LDAC codec for high-resolution audio streaming from compatible devices. The in-ear canal design is intended to provide a secure fit for passive noise isolation during extended use. Audio output can be modified using a companion application with EQ presets and customization settings.
