Anker Soundcore Liberty 4 Pro Wireless Earbuds, Blue

The Anker Soundcore Liberty 4 Pro are true wireless earphones built around 10.5 mm dynamic drivers within a closed-back acoustic system. This configuration supports a frequency response range of 14 Hz to 40,000 Hz. The in-ear, canal-style design is intended to provide passive noise isolation, aided by the inclusion of multiple ear tip sizes for a secure fit. For device pairing, the earphones utilize Bluetooth 5.3 technology and are compatible with standard HFP, A2DP, and AVRCP profiles.

These earphones incorporate an adaptive noise cancellation system that adjusts its performance based on the surrounding environment. Voice communication is handled by a six-microphone array with digital signal processing to reduce background noise. A single charge provides up to 10 hours of continuous audio playback, and the companion charging case recharges via a USB-C port. The construction carries an IPX5 rating, indicating resistance to water splashes from any direction, making them suitable for use during exercise.
