What reviewers say
Distilled from the video reviewers — the score, what they praise, where they push back.?
Reviewers praise
- Active noise cancellation performs at a high level, comparable to earbuds that cost significantly more
- Battery life is exceptional with ten hours from the earbuds and fifty hours total with the case
- Feature set is comprehensive including LDAC support, multi-point connectivity, wireless charging, and extensive customization options in the app
Reviewers push back
- Microphone call quality is inconsistent, with some reviewers reporting colleagues and callers struggled to hear them clearly, particularly with deeper voices
- Transparency mode is weak, suppressing ambient sound too much and requiring users to remove the buds for conversations
- Touch sensor placement requires precise tapping on the stem or it fails to register the command
Reviewers agree the Liberty 4 NC delivers strong active noise cancellation and exceptional battery life at a low price, though microphone quality and transparency mode disappoint.
Microphone performance varied wildly between reviewers—one reported persistent complaints from colleagues and family, while another had no issues except with WhatsApp call routing
