After spending several weeks with the Soundcore Liberty 4 NC earbuds (model numbers: A3947, A3947H31, A3947Z31, A3947G31), I’m ready to share my in-depth review. These earbuds promise impressive noise cancellation, exceptional sound quality, and a remarkably long battery life. Let’s dive into whether they deliver on these bold claims.

Key Features

The Liberty 4 NC earbuds pack a punch in terms of features. The standout feature is undoubtedly the advertised 98.5% noise cancellation. Beyond that, we have Hi-Res audio support via LDAC codec, a comfortable fit thanks to multiple ear tip sizes, and a claimed 50-hour total battery life with the charging case. The inclusion of wireless charging is also a welcome addition for convenient power management. Bluetooth 5.3 ensures a stable and efficient connection.

Performance & Sound Quality

The noise cancellation on the Liberty 4 NC is genuinely impressive. I tested them on commutes, busy streets, and even during a flight. While not reaching the full 98.5% advertised, they effectively muted a significant portion of background noise, leaving me with a peaceful listening experience. The adaptive ANC 2.0 does an admirable job adjusting to different environments. Sound quality is crisp and detailed. The 11mm drivers deliver rich bass, clear mids, and well-defined highs. The Hi-Res audio capability is noticeable, offering a richer and more nuanced listening experience compared to standard Bluetooth codecs. Battery life also lived up to expectations; I consistently achieved around 8 hours of playtime on a single charge, and the charging case easily extended that to the advertised 50 hours.

One small area for improvement might be the call quality. While calls were generally clear, I experienced some slight background noise bleed-through in louder environments. This wasn’t a major issue, but it’s worth noting.

Pros & Cons

• Pros: Excellent noise cancellation, impressive sound quality, very long battery life, comfortable fit, wireless charging, Hi-Res Audio support.
• Cons: Minor background noise bleed-through during calls in noisy environments, slightly bulky charging case.

Final Verdict

The Soundcore Liberty 4 NC earbuds offer a compelling package of features and performance. The exceptional noise cancellation, superb sound quality, and incredibly long battery life make them a strong contender in the crowded wireless earbuds market. While minor improvements could be made to call quality and perhaps the charging case’s size, these are small shortcomings overshadowed by the overall excellent experience. I highly recommend the Liberty 4 NC earbuds to anyone seeking a high-quality, feature-rich pair of wireless earbuds.
