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
