Why Choose Liberty 4 NC?
Whether you’re navigating a noisy airport, catching up on work during a long flight, or enjoying music at home, the soundcore Liberty 4 NC delivers exceptional performance across all scenarios. The Adaptive ANC 2.0 system continuously monitors external noise and your ear canal fit, making real-time adjustments to maintain optimal noise cancellation—no manual tweaking required. This means you’ll enjoy consistent quiet whether you’re on a subway, in a busy office, or walking through a park.
The dual-driver system combines an 11mm custom-tuned dynamic driver with a 4.6mm balanced armature to deliver rich bass, crisp highs, and detailed midrange. Paired with Hi-Res wireless audio certification and LDAC codec support, these earbuds reproduce music the way artists intended. For personalized listening, HearID 2.0 analyzes your hearing profile to optimize sound settings specifically for you. You can also fine-tune everything yourself using the companion app’s full EQ control or browse 22 built-in presets designed for different genres and preferences.
Battery life is equally impressive. In normal mode, you get up to 10 hours per charge—extendable to 50 hours with the included charging case. When noise cancellation is active, expect 8 hours of playback (40 hours total with the case). Fast charging gives you an hour of use after just 5 minutes plugged in, making it easy to top off before heading out. And with wireless charging compatibility, you can power up without fumbling cables.
Connectivity is seamless thanks to Bluetooth 5.3, which offers faster pairing, improved stability, and lower latency compared to previous versions. Auto-pause/play activates when you remove an earbud, while multi-point pairing lets you connect to two devices simultaneously—great for switching between your laptop and smartphone. The touch controls are intuitive: tap to play/pause, double-tap to skip tracks, or hold to activate your device’s voice assistant.
Durability matters too. With an IPX4 rating, the Liberty 4 NC stands up to sweat, light rain, and accidental spills—perfect for workouts, commutes, or outdoor adventures. The ergonomic design ensures a secure fit for most ears, and six sets of silicone tips are included to help you find your perfect seal. At just 5g per earbud, they feel lightweight even during extended wear.
