Anker Soundcore Liberty 4 NC Wireless Earbuds, Blue

The Anker Soundcore Liberty 4 NC are true wireless earbuds equipped with 11 mm dynamic drivers that support a frequency range of 20 Hz to 40,000 Hz. They feature Adaptive ANC 2.0, a system that adjusts noise cancellation levels in real-time according to the user's surrounding environment. The in-ear canal design, paired with four included sizes of silicone ear tips, is intended to create a secure seal for passive noise isolation and audio delivery. These earbuds establish a wireless connection to devices using Bluetooth 5.3 technology, which supports A2DP, AVRCP, and HFP profiles.

For voice calls, the earbuds integrate a six-microphone array combined with a noise-canceling algorithm to help isolate speech from ambient sounds. The battery provides up to 10 hours of continuous audio playback on a single charge, with the charging case extending the total listening time to 50 hours. The case itself recharges via a USB-C port and supports fast charging for the earbuds. Users can manage playback, calls, and noise cancellation modes through the on-device touch controls. The earbuds have an IPX4 rating, indicating they are resistant to water splashes from any direction.
