Anker Soundcore Liberty 4 NC Wireless Earbuds, Black

The Anker Soundcore Liberty 4 NC are true wireless earbuds equipped with 11 mm dynamic drivers. They are designed to support high-resolution audio, with a frequency response of 20 Hz to 40,000 Hz and compatibility with the LDAC codec for enhanced streaming quality. The in-ear form factor provides a secure fit and a degree of passive sound isolation from ambient noise. Connection to source devices is established via Bluetooth 5.3, which offers a wireless range of up to 20 meters.

These earbuds integrate Adaptive ANC 2.0, a system that automatically adjusts the level of noise cancellation to match the user's surroundings. For voice calls, a six-microphone array with a noise-reduction algorithm is utilized to improve vocal clarity. The earbuds provide up to 10 hours of continuous playback on a single charge, and the included charging case extends the total operational time to 50 hours. An IPX4 rating signifies resistance to water splashes, and on-device touch controls manage playback, calls, and noise control modes.
