Liberty 4 NC Wireless Noise Cancelling Earbuds - Adaptive ANC, Hi-Res

Our review finds the Liberty 4 NC earbuds are best for commuters and frequent travelers who want powerful noise reduction without bulky over-ear headphones. In this review the standout is the adaptive noise cancelling system that actively tailors suppression to your ear canals and surroundings, delivering notably quieter cabins, trains and busy streets. Combined with 11mm drivers and LDAC Hi-Res support, these buds aim to balance deep noise suppression with clear, detailed audio, while long battery life and wireless charging make them a practical daily companion.

Key Features

• Up to 98.5% noise reduction: A high sensitivity in-ear sound sensor and noise isolation chamber work together to cancel a very high proportion of external noise for calmer listening.
• Adaptive ANC 2.0: The system adjusts in real time to your ear canals and environment so noise cancellation stays effective in changing situations.
• Hi-Res sound with LDAC: 11mm custom-tuned drivers and LDAC wireless transfer deliver more audio data than standard Bluetooth for clearer, more detailed playback.
• Personalized sound profile: HearID 2.0 generates a tailored EQ and you can choose from 22 presets or fully adjust the EQ to suit tastes.
• Long battery life: Up to 10 hours per charge in normal mode (8 hours with ANC on) and up to 50 hours total with the charging case.
• Clear calls and water resistance: Six beamforming mics with AI voice enhancement improve call clarity and the IPX4 rating protects against splashes.

Who It's For

The Liberty 4 NC is ideal for daily commuters, frequent flyers and anyone who wants aggressive noise cancelling in a compact in-ear package. If you stream high-resolution music or use Android devices that support LDAC, you will benefit from noticeably richer wireless audio and the customizable HearID 2.0 options.

These earbuds may not be the right choice if you need fully waterproof buds for swimming or rigorous workouts, or if you prefer a simpler, ultra-basic pair with no app-based tuning. Users who experience intermittent connectivity glitches should weigh those reports against the strong ANC and sound quality.
