Soundcore Liberty 4 NC True‑Wireless Earbuds | A3947H21

The Soundcore Liberty 4 NC (A3947H21) in white are high-performance true-wireless earbuds featuring Adaptive ANC 2.0, which dynamically adjusts the noise cancellation to both your ear canal and surrounding environment. These earbuds can reduce up to 98.5% of ambient noise, giving you quiet for travel, work, or focus. Sound is driven by 11 mm custom-tuned drivers and supports Hi-Res wireless audio via LDAC, so you get very detailed, rich sound.

You get up to 10 hours of playback per charge (with ANC off) and a total of 50 hours when including the charging case. For quick boosts, 10 minutes of charging gives ~4 hours of playtime. Connectivity is via Bluetooth 5.3 with multipoint support (you can connect to two devices at once). Call quality is enhanced through 6 microphones and an AI algorithm to reduce background noise while preserving your voice. The earbuds are rated IPX4 for water resistance, making them resilient to light splashes. Through the Soundcore app, you can customize your sound using HearID 2.0 and an adjustable EQ, plus toggle ANC / ambient modes.
