soundcore Liberty 4 NC 50H battery earbuds
Product description
The Liberty 4 NC are wireless noise cancelling earbuds from soundcore by Anker that aim to make noisy commutes and busy days quieter while keeping music detailed and natural. They combine adaptive ANC, Hi‑Res wireless audio with LDAC and a long battery life to suit travel and daily listening.
Key points
Adaptive ANC adjusts in real time to your ear canals and surroundings to reduce background noise according to the manufacturer, with an in‑ear sensor and a noise isolation chamber that claims up to 98.5% noise reduction. Battery life is practical for long days, offering about 10 hours per charge in normal mode and up to 50 hours with the charging case, or 8 hours with ANC on and up to 40 hours with the case. Sound is delivered through 11mm custom‑tuned drivers and Hi‑Res LDAC support for richer wireless audio. The buds also offer IPX4 water resistance and features such as auto play and pause, multi‑point Bluetooth 5.3, wireless charging and HearID 2.0 customisation.

Benefits
These earbuds balance strong noise suppression with a focus on clarity, which helps when you need quiet to concentrate or to hear music with more detail. The HearID 2.0 profile and adjustable EQ let you shape the sound without fuss, and LDAC support transfers more audio data over Bluetooth for better fidelity when your device supports it. A modest caveat is that advanced codecs and top Hi‑Res results depend on compatible devices.
Usage tips
It’s a good fit if you commute, travel or work in shared spaces and want substantial noise reduction without bulky over‑ears. Try different ear tips and run the HearID 2.0 test to optimise the fit and sound. For longer journeys switch to the case between uses to extend total listening time, and enable multi‑point to keep two devices connected smoothly.
