PRODUCT DESCRIPTION
Adaptive ANC 2.0 with Real-Time Calibration (98.5% Noise Reduction)
The Soundcore Liberty 4 NC operates on Anker’s precise Adaptive ANC 2.0 technology. It employs highly sensitive sound sensors placed inside the ear, as well as external microphones, to monitor environmental frequency levels and even the acoustics of your ear canal in real-time in order to correct noise suppression filters in microseconds. As a result, certified noise cancellation performance reaches 98.5%, eliminating sounds from the aircraft cabin, metropolitan traffic, or even the buzzing atmosphere of an open office.
High-Resolution Wireless Audio and HearID 2.0 Sound Modification
The Liberty 4 NC boasts a set of advanced 11mm dynamic driver units manufactured from high-stretch, resilient liquid crystal polymer (LCP). The drivers produce an excellent sound quality with strong bass response, clear mid-frequency sounds, and bright treble tones. Thanks to the integration of the Sony LDAC codec, the Liberty 4 NC achieves the ability to send three times more data than standard Bluetooth protocols so that you can enjoy Hi-Res Audio Wireless certified experience. Moreover, the Soundcore app introduces users to HearID 2.0.
Battery Life at 50 hours, Multiple microphones with AI support and Wireless Charging Capability
